-/******************************************************************************
-** This file is an amalgamation of many separate C source files from SQLite
-** version 3.35.0. By combining all the individual C code files into this
-** single large file, the entire code can be compiled as a single translation
-** unit. This allows many compilers to do optimizations that would not be
-** possible if the files were compiled separately. Performance improvements
-** of 5% or more are commonly seen when SQLite is compiled as a single
-** translation unit.
-**
-** This file is all you need to compile SQLite. To use SQLite in other
-** programs, you need this file and the "sqlite3.h" header file that defines
-** the programming interface to the SQLite library. (If you do not have
-** the "sqlite3.h" header file at hand, you will find a copy embedded within
-** the text of this file. Search for "Begin file sqlite3.h" to find the start
-** of the embedded sqlite3.h header file.) Additional code files may be needed
-** if you want a wrapper to interface SQLite with your choice of programming
-** language. The code for the "sqlite3" command-line shell is also in a
-** separate file. This file contains only code for the core SQLite library.

-** ^The sqlite3_threadsafe() function returns zero if and only if

-**
-** SQLite can be compiled with or without mutexes. When

-** are enabled and SQLite is threadsafe. When the

-** the mutexes are omitted. Without the mutexes, it is not safe
-** to use SQLite concurrently from more than one thread.
-**
-** Enabling mutexes incurs a measurable performance penalty.
-** So if speed is of utmost importance, it makes sense to disable
-** the mutexes. But for maximum safety, mutexes should be enabled.
-** ^The default behavior is for mutexes to be enabled.
-**
-** This interface can be used by an application to make sure that the
-** version of SQLite that it is linking against was compiled with
-** the desired setting of the [SQLITE_THREADSAFE] macro.
-**
-** This interface only reports on the compile-time mutex setting

-** that allows an application to run multiple statements of SQL
-** without having to use a lot of C code.

-** ^The sqlite3_exec() interface runs zero or more UTF-8 encoded,

-** coming out of the evaluated SQL statements. ^The 4th argument to
-** sqlite3_exec() is relayed through to the 1st argument of each
-** callback invocation. ^If the callback pointer to sqlite3_exec()
-** is NULL, then no callback is ever invoked and result rows are
-** ignored.
-**
-** ^If an error occurs while evaluating the SQL statements passed into

-** subsequent statements are skipped. ^If the 5th parameter to sqlite3_exec()
-** is not NULL then any error message is written into memory obtained
-** from [sqlite3_malloc()] and passed back through the 5th parameter.
-** To avoid memory leaks, the application should invoke [sqlite3_free()]
-** on error message strings returned through the 5th parameter of
-** sqlite3_exec() after the error message string is no longer needed.
-** ^If the 5th parameter to sqlite3_exec() is not NULL and no errors
-** occur, then sqlite3_exec() sets the pointer in its 5th parameter to
-** NULL before returning.
-**
-** ^If an sqlite3_exec() callback returns non-zero, the sqlite3_exec()
-** routine returns SQLITE_ABORT without invoking the callback again and
-** without running any subsequent SQL statements.
-**
-** ^The 2nd argument to the sqlite3_exec() callback function is the
-** number of columns in the result. ^The 3rd argument to the sqlite3_exec()
-** callback is an array of pointers to strings obtained as if from
-** [sqlite3_column_text()], one for each column. ^If an element of a
-** result row is NULL then the corresponding string pointer for the
-** sqlite3_exec() callback is a NULL pointer. ^The 4th argument to the
-** sqlite3_exec() callback is an array of pointers to strings where each

-**

-** CAPI3REF: OS Interface File Virtual Methods Object
-**
-** Every file opened by the [sqlite3_vfs.xOpen] method populates an
-** [sqlite3_file] object (or, more commonly, a subclass of the
-** [sqlite3_file] object) with a pointer to an instance of this object.
-** This object defines the methods used to perform various operations
-** against the open file represented by the [sqlite3_file] object.
-**
-** If the [sqlite3_vfs.xOpen] method sets the sqlite3_file.pMethods element
-** to a non-NULL pointer, then the sqlite3_io_methods.xClose method
-** may be invoked even if the [sqlite3_vfs.xOpen] reported that it failed. The
-** only way to prevent a call to xClose following a failed [sqlite3_vfs.xOpen]
-** is for the [sqlite3_vfs.xOpen] to set the sqlite3_file.pMethods element
-** to NULL.
-**
-** The flags argument to xSync may be one of [SQLITE_SYNC_NORMAL] or
-** [SQLITE_SYNC_FULL]. The first choice is the normal fsync().
-** The second choice is a Mac OS X style fullsync. The [SQLITE_SYNC_DATAONLY]
-** flag may be ORed in to indicate that only the data of the file
-** and not its inode needs to be synced.
-**
-** The integer values to xLock() and xUnlock() are one of
-**
-** - [SQLITE_LOCK_NONE],
-**
- [SQLITE_LOCK_SHARED],
-**
- [SQLITE_LOCK_RESERVED],
-**
- [SQLITE_LOCK_PENDING], or
-**
- [SQLITE_LOCK_EXCLUSIVE].
-**
-** xLock() increases the lock. xUnlock() decreases the lock.
-** The xCheckReservedLock() method checks whether any database connection,
-** either in this process or in some other process, is holding a RESERVED,
-** PENDING, or EXCLUSIVE lock on the file. It returns true
-** if such a lock exists and false otherwise.
-**
-** The xFileControl() method is a generic interface that allows custom
-** VFS implementations to directly control an open file using the
-** [sqlite3_file_control()] interface. The second "op" argument is an
-** integer opcode. The third argument is a generic pointer intended to
-** point to a structure that may contain arguments or space in which to
-** write return values. Potential uses for xFileControl() might be
-** functions to enable blocking locks with timeouts, to change the
-** locking strategy (for example to use dot-file locks), to inquire
-** about the status of a lock, or to break stale locks. The SQLite
-** core reserves all opcodes less than 100 for its own use.
-** A [file control opcodes | list of opcodes] less than 100 is available.
-** Applications that define a custom xFileControl method should use opcodes
-** greater than 100 to avoid conflicts. VFS implementations should
-** return [SQLITE_NOTFOUND] for file control opcodes that they do not
-** recognize.
-**
-** The xSectorSize() method returns the sector size of the
-** device that underlies the file. The sector size is the
-** minimum write that can be performed without disturbing
-** other bytes in the file. The xDeviceCharacteristics()
-** method returns a bit vector describing behaviors of the
-** underlying device:

-**
- [SQLITE_IOCAP_POWERSAFE_OVERWRITE]
-**
- [SQLITE_IOCAP_IMMUTABLE]
-**
- [SQLITE_IOCAP_BATCH_ATOMIC]
-**
-**
-** The SQLITE_IOCAP_ATOMIC property means that all writes of
-** any size are atomic. The SQLITE_IOCAP_ATOMICnnn values
-** mean that writes of blocks that are nnn bytes in size and
-** are aligned to an address which is an integer multiple of
-** nnn are atomic. The SQLITE_IOCAP_SAFE_APPEND value means
-** that when data is appended to a file, the data is appended
-** first then the size of the file is extended, never the other
-** way around. The SQLITE_IOCAP_SEQUENTIAL property means that
-** information is written to disk in the same order as calls
-** to xWrite().
-**
-** If xRead() returns SQLITE_IOERR_SHORT_READ it must also fill
-** in the unread portions of the buffer with zeros. A VFS that
-** fails to zero-fill short reads might seem to work. However,
-** failure to zero-fill short reads will eventually lead to
-** database corruption.

-** CAPI3REF: Standard File Control Opcodes
-** KEYWORDS: {file control opcodes} {file control opcode}
-**
-** These integer constants are opcodes for the xFileControl method
-** of the [sqlite3_io_methods] object and for the [sqlite3_file_control()]
-** interface.
-**
-**
-** - [[SQLITE_FCNTL_LOCKSTATE]]
-** The [SQLITE_FCNTL_LOCKSTATE] opcode is used for debugging. This
-** opcode causes the xFileControl method to write the current state of
-** the lock (one of [SQLITE_LOCK_NONE], [SQLITE_LOCK_SHARED],
-** [SQLITE_LOCK_RESERVED], [SQLITE_LOCK_PENDING], or [SQLITE_LOCK_EXCLUSIVE])
-** into an integer that the pArg argument points to. This capability
-** is used during testing and is only available when the SQLITE_TEST
-** compile-time option is used.
-**
-**
- [[SQLITE_FCNTL_SIZE_HINT]]
-** The [SQLITE_FCNTL_SIZE_HINT] opcode is used by SQLite to give the VFS
-** layer a hint of how large the database file will grow to be during the
-** current transaction. This hint is not guaranteed to be accurate but it
-** is often close. The underlying VFS might choose to preallocate database
-** file space based on this hint in order to help writes to the database
-** file run faster.
-**
-**
- [[SQLITE_FCNTL_SIZE_LIMIT]]
-** The [SQLITE_FCNTL_SIZE_LIMIT] opcode is used by in-memory VFS that
-** implements [sqlite3_deserialize()] to set an upper bound on the size
-** of the in-memory database. The argument is a pointer to a [sqlite3_int64].
-** If the integer pointed to is negative, then it is filled in with the
-** current limit. Otherwise the limit is set to the larger of the value
-** of the integer pointed to and the current database size. The integer
-** pointed to is set to the new limit.
-**
-**
- [[SQLITE_FCNTL_CHUNK_SIZE]]
-** The [SQLITE_FCNTL_CHUNK_SIZE] opcode is used to request that the VFS
-** extends and truncates the database file in chunks of a size specified
-** by the user. The fourth argument to [sqlite3_file_control()] should
-** point to an integer (type int) containing the new chunk-size to use
-** for the nominated database. Allocating database file space in large
-** chunks (say 1MB at a time), may reduce file-system fragmentation and
-** improve performance on some systems.
-**
-**
- [[SQLITE_FCNTL_FILE_POINTER]]
-** The [SQLITE_FCNTL_FILE_POINTER] opcode is used to obtain a pointer
-** to the [sqlite3_file] object associated with a particular database
-** connection. See also [SQLITE_FCNTL_JOURNAL_POINTER].
-**
-**
- [[SQLITE_FCNTL_JOURNAL_POINTER]]
-** The [SQLITE_FCNTL_JOURNAL_POINTER] opcode is used to obtain a pointer
-** to the [sqlite3_file] object associated with the journal file (either
-** the [rollback journal] or the [write-ahead log]) for a particular database
-** connection. See also [SQLITE_FCNTL_FILE_POINTER].
-**
-**
- [[SQLITE_FCNTL_SYNC_OMITTED]]
-** No longer in use.
-**
-**
- [[SQLITE_FCNTL_SYNC]]
-** The [SQLITE_FCNTL_SYNC] opcode is generated internally by SQLite and
-** sent to the VFS immediately before the xSync method is invoked on a
-** database file descriptor. Or, if the xSync method is not invoked
-** because the user has configured SQLite with
-** [PRAGMA synchronous | PRAGMA synchronous=OFF] it is invoked in place
-** of the xSync method. In most cases, the pointer argument passed with
-** this file-control is NULL. However, if the database file is being synced
-** as part of a multi-database commit, the argument points to a nul-terminated
-** string containing the transactions super-journal file name. VFSes that
-** do not need this signal should silently ignore this opcode. Applications
-** should not call [sqlite3_file_control()] with this opcode as doing so may
-** disrupt the operation of the specialized VFSes that do require it.
-**
-**
- [[SQLITE_FCNTL_COMMIT_PHASETWO]]
-** The [SQLITE_FCNTL_COMMIT_PHASETWO] opcode is generated internally by SQLite
-** and sent to the VFS after a transaction has been committed immediately
-** but before the database is unlocked. VFSes that do not need this signal
-** should silently ignore this opcode. Applications should not call
-** [sqlite3_file_control()] with this opcode as doing so may disrupt the
-** operation of the specialized VFSes that do require it.
-**
-**
- [[SQLITE_FCNTL_WIN32_AV_RETRY]]
-** ^The [SQLITE_FCNTL_WIN32_AV_RETRY] opcode is used to configure automatic
-** retry counts and intervals for certain disk I/O operations for the
-** windows [VFS] in order to provide robustness in the presence of
-** anti-virus programs. By default, the windows VFS will retry file read,
-** file write, and file delete operations up to 10 times, with a delay
-** of 25 milliseconds before the first retry and with the delay increasing
-** by an additional 25 milliseconds with each subsequent retry. This
-** opcode allows these two values (10 retries and 25 milliseconds of delay)
-** to be adjusted. The values are changed for all database connections
-** within the same process. The argument is a pointer to an array of two
-** integers where the first integer is the new retry count and the second
-** integer is the delay. If either integer is negative, then the setting
-** is not changed but instead the prior value of that setting is written
-** into the array entry, allowing the current retry settings to be
-** interrogated. The zDbName parameter is ignored.
-**
-**
- [[SQLITE_FCNTL_PERSIST_WAL]]
-** ^The [SQLITE_FCNTL_PERSIST_WAL] opcode is used to set or query the
-** persistent [WAL | Write Ahead Log] setting. By default, the auxiliary
-** write ahead log ([WAL file]) and shared memory
-** files used for transaction control
-** are automatically deleted when the latest connection to the database
-** closes. Setting persistent WAL mode causes those files to persist after
-** close. Persisting the files is useful when other processes that do not
-** have write permission on the directory containing the database file want
-** to read the database file, as the WAL and shared memory files must exist
-** in order for the database to be readable. The fourth parameter to
-** [sqlite3_file_control()] for this opcode should be a pointer to an integer.
-** That integer is 0 to disable persistent WAL mode or 1 to enable persistent
-** WAL mode. If the integer is -1, then it is overwritten with the current
-** WAL persistence setting.
-**
-**
- [[SQLITE_FCNTL_POWERSAFE_OVERWRITE]]
-** ^The [SQLITE_FCNTL_POWERSAFE_OVERWRITE] opcode is used to set or query the
-** persistent "powersafe-overwrite" or "PSOW" setting. The PSOW setting
-** determines the [SQLITE_IOCAP_POWERSAFE_OVERWRITE] bit of the
-** xDeviceCharacteristics methods. The fourth parameter to
-** [sqlite3_file_control()] for this opcode should be a pointer to an integer.
-** That integer is 0 to disable zero-damage mode or 1 to enable zero-damage
-** mode. If the integer is -1, then it is overwritten with the current
-** zero-damage mode setting.
-**
-**
- [[SQLITE_FCNTL_OVERWRITE]]
-** ^The [SQLITE_FCNTL_OVERWRITE] opcode is invoked by SQLite after opening
-** a write transaction to indicate that, unless it is rolled back for some
-** reason, the entire database file will be overwritten by the current
-** transaction. This is used by VACUUM operations.
-**
-**
- [[SQLITE_FCNTL_VFSNAME]]
-** ^The [SQLITE_FCNTL_VFSNAME] opcode can be used to obtain the names of
-** all [VFSes] in the VFS stack. The names are of all VFS shims and the
-** final bottom-level VFS are written into memory obtained from
-** [sqlite3_malloc()] and the result is stored in the char* variable
-** that the fourth parameter of [sqlite3_file_control()] points to.
-** The caller is responsible for freeing the memory when done. As with
-** all file-control actions, there is no guarantee that this will actually
-** do anything. Callers should initialize the char* variable to a NULL
-** pointer in case this file-control is not implemented. This file-control
-** is intended for diagnostic use only.
-**
-**
- [[SQLITE_FCNTL_VFS_POINTER]]
-** ^The [SQLITE_FCNTL_VFS_POINTER] opcode finds a pointer to the top-level
-** [VFSes] currently in use. ^(The argument X in
-** sqlite3_file_control(db,SQLITE_FCNTL_VFS_POINTER,X) must be
-** of type "[sqlite3_vfs] **". This opcodes will set *X
-** to a pointer to the top-level VFS.)^
-** ^When there are multiple VFS shims in the stack, this opcode finds the
-** upper-most shim only.
-**
-**
- [[SQLITE_FCNTL_PRAGMA]]
-** ^Whenever a [PRAGMA] statement is parsed, an [SQLITE_FCNTL_PRAGMA]
-** file control is sent to the open [sqlite3_file] object corresponding
-** to the database file to which the pragma statement refers. ^The argument
-** to the [SQLITE_FCNTL_PRAGMA] file control is an array of
-** pointers to strings (char**) in which the second element of the array
-** is the name of the pragma and the third element is the argument to the
-** pragma or NULL if the pragma has no argument. ^The handler for an
-** [SQLITE_FCNTL_PRAGMA] file control can optionally make the first element
-** of the char** argument point to a string obtained from [sqlite3_mprintf()]
-** or the equivalent and that string will become the result of the pragma or
-** the error message if the pragma fails. ^If the
-** [SQLITE_FCNTL_PRAGMA] file control returns [SQLITE_NOTFOUND], then normal
-** [PRAGMA] processing continues. ^If the [SQLITE_FCNTL_PRAGMA]
-** file control returns [SQLITE_OK], then the parser assumes that the
-** VFS has handled the PRAGMA itself and the parser generates a no-op
-** prepared statement if result string is NULL, or that returns a copy
-** of the result string if the string is non-NULL.
-** ^If the [SQLITE_FCNTL_PRAGMA] file control returns
-** any result code other than [SQLITE_OK] or [SQLITE_NOTFOUND], that means
-** that the VFS encountered an error while handling the [PRAGMA] and the
-** compilation of the PRAGMA fails with an error. ^The [SQLITE_FCNTL_PRAGMA]
-** file control occurs at the beginning of pragma statement analysis and so
-** it is able to override built-in [PRAGMA] statements.
-**
-**
- [[SQLITE_FCNTL_BUSYHANDLER]]
-** ^The [SQLITE_FCNTL_BUSYHANDLER]
-** file-control may be invoked by SQLite on the database file handle
-** shortly after it is opened in order to provide a custom VFS with access
-** to the connection's busy-handler callback. The argument is of type (void**)
-** - an array of two (void *) values. The first (void *) actually points
-** to a function of type (int (*)(void *)). In order to invoke the connection's
-** busy-handler, this function should be invoked with the second (void *) in
-** the array as the only argument. If it returns non-zero, then the operation
-** should be retried. If it returns zero, the custom VFS should abandon the
-** current operation.
-**
-**
- [[SQLITE_FCNTL_TEMPFILENAME]]
-** ^Applications can invoke the [SQLITE_FCNTL_TEMPFILENAME] file-control
-** to have SQLite generate a
-** temporary filename using the same algorithm that is followed to generate
-** temporary filenames for TEMP tables and other internal uses. The
-** argument should be a char** which will be filled with the filename
-** written into memory obtained from [sqlite3_malloc()]. The caller should
-** invoke [sqlite3_free()] on the result to avoid a memory leak.
-**
-**
- [[SQLITE_FCNTL_MMAP_SIZE]]
-** The [SQLITE_FCNTL_MMAP_SIZE] file control is used to query or set the
-** maximum number of bytes that will be used for memory-mapped I/O.
-** The argument is a pointer to a value of type sqlite3_int64 that
-** is an advisory maximum number of bytes in the file to memory map. The
-** pointer is overwritten with the old value. The limit is not changed if
-** the value originally pointed to is negative, and so the current limit
-** can be queried by passing in a pointer to a negative number. This
-** file-control is used internally to implement [PRAGMA mmap_size].
-**
-**
- [[SQLITE_FCNTL_TRACE]]
-** The [SQLITE_FCNTL_TRACE] file control provides advisory information
-** to the VFS about what the higher layers of the SQLite stack are doing.
-** This file control is used by some VFS activity tracing [shims].
-** The argument is a zero-terminated string. Higher layers in the
-** SQLite stack may generate instances of this file control if
-** the [SQLITE_USE_FCNTL_TRACE] compile-time option is enabled.
-**
-**
- [[SQLITE_FCNTL_HAS_MOVED]]
-** The [SQLITE_FCNTL_HAS_MOVED] file control interprets its argument as a
-** pointer to an integer and it writes a boolean into that integer depending
-** on whether or not the file has been renamed, moved, or deleted since it
-** was first opened.
-**
-**
- [[SQLITE_FCNTL_WIN32_GET_HANDLE]]
-** The [SQLITE_FCNTL_WIN32_GET_HANDLE] opcode can be used to obtain the
-** underlying native file handle associated with a file handle. This file
-** control interprets its argument as a pointer to a native file handle and
-** writes the resulting value there.
-**
-**
- [[SQLITE_FCNTL_WIN32_SET_HANDLE]]
-** The [SQLITE_FCNTL_WIN32_SET_HANDLE] opcode is used for debugging. This
-** opcode causes the xFileControl method to swap the file handle with the one
-** pointed to by the pArg argument. This capability is used during testing
-** and only needs to be supported when SQLITE_TEST is defined.
-**
-**
- [[SQLITE_FCNTL_WAL_BLOCK]]
-** The [SQLITE_FCNTL_WAL_BLOCK] is a signal to the VFS layer that it might
-** be advantageous to block on the next WAL lock if the lock is not immediately
-** available. The WAL subsystem issues this signal during rare
-** circumstances in order to fix a problem with priority inversion.
-** Applications should not use this file-control.
-**
-**
- [[SQLITE_FCNTL_ZIPVFS]]
-** The [SQLITE_FCNTL_ZIPVFS] opcode is implemented by zipvfs only. All other
-** VFS should return SQLITE_NOTFOUND for this opcode.
-**
-**
- [[SQLITE_FCNTL_RBU]]
-** The [SQLITE_FCNTL_RBU] opcode is implemented by the special VFS used by
-** the RBU extension only. All other VFS should return SQLITE_NOTFOUND for
-** this opcode.
-**
-**
- [[SQLITE_FCNTL_BEGIN_ATOMIC_WRITE]]
-** If the [SQLITE_FCNTL_BEGIN_ATOMIC_WRITE] opcode returns SQLITE_OK, then
-** the file descriptor is placed in "batch write mode", which
-** means all subsequent write operations will be deferred and done
-** atomically at the next [SQLITE_FCNTL_COMMIT_ATOMIC_WRITE]. Systems
-** that do not support batch atomic writes will return SQLITE_NOTFOUND.
-** ^Following a successful SQLITE_FCNTL_BEGIN_ATOMIC_WRITE and prior to
-** the closing [SQLITE_FCNTL_COMMIT_ATOMIC_WRITE] or
-** [SQLITE_FCNTL_ROLLBACK_ATOMIC_WRITE], SQLite will make
-** no VFS interface calls on the same [sqlite3_file] file descriptor
-** except for calls to the xWrite method and the xFileControl method
-** with [SQLITE_FCNTL_SIZE_HINT].
-**
-**
- [[SQLITE_FCNTL_COMMIT_ATOMIC_WRITE]]
-** The [SQLITE_FCNTL_COMMIT_ATOMIC_WRITE] opcode causes all write
-** operations since the previous successful call to
-** [SQLITE_FCNTL_BEGIN_ATOMIC_WRITE] to be performed atomically.
-** This file control returns [SQLITE_OK] if and only if the writes were
-** all performed successfully and have been committed to persistent storage.
-** ^Regardless of whether or not it is successful, this file control takes
-** the file descriptor out of batch write mode so that all subsequent
-** write operations are independent.
-** ^SQLite will never invoke SQLITE_FCNTL_COMMIT_ATOMIC_WRITE without
-** a prior successful call to [SQLITE_FCNTL_BEGIN_ATOMIC_WRITE].
-**
-**
- [[SQLITE_FCNTL_ROLLBACK_ATOMIC_WRITE]]
-** The [SQLITE_FCNTL_ROLLBACK_ATOMIC_WRITE] opcode causes all write
-** operations since the previous successful call to
-** [SQLITE_FCNTL_BEGIN_ATOMIC_WRITE] to be rolled back.
-** ^This file control takes the file descriptor out of batch write mode
-** so that all subsequent write operations are independent.
-** ^SQLite will never invoke SQLITE_FCNTL_ROLLBACK_ATOMIC_WRITE without
-** a prior successful call to [SQLITE_FCNTL_BEGIN_ATOMIC_WRITE].
-**
-**
- [[SQLITE_FCNTL_LOCK_TIMEOUT]]
-** The [SQLITE_FCNTL_LOCK_TIMEOUT] opcode is used to configure a VFS
-** to block for up to M milliseconds before failing when attempting to
-** obtain a file lock using the xLock or xShmLock methods of the VFS.
-** The parameter is a pointer to a 32-bit signed integer that contains
-** the value that M is to be set to. Before returning, the 32-bit signed
-** integer is overwritten with the previous value of M.
-**
-**
- [[SQLITE_FCNTL_DATA_VERSION]]
-** The [SQLITE_FCNTL_DATA_VERSION] opcode is used to detect changes to
-** a database file. The argument is a pointer to a 32-bit unsigned integer.
-** The "data version" for the pager is written into the pointer. The
-** "data version" changes whenever any change occurs to the corresponding
-** database file, either through SQL statements on the same database
-** connection or through transactions committed by separate database
-** connections possibly in other processes. The [sqlite3_total_changes()]
-** interface can be used to find if any database on the connection has changed,
-** but that interface responds to changes on TEMP as well as MAIN and does
-** not provide a mechanism to detect changes to MAIN only. Also, the
-** [sqlite3_total_changes()] interface responds to internal changes only and
-** omits changes made by other database connections. The
-** [PRAGMA data_version] command provides a mechanism to detect changes to
-** a single attached database that occur due to other database connections,
-** but omits changes implemented by the database connection on which it is
-** called. This file control is the only mechanism to detect changes that
-** happen either internally or externally and that are associated with
-** a particular attached database.
-**
-**
- [[SQLITE_FCNTL_CKPT_START]]
-** The [SQLITE_FCNTL_CKPT_START] opcode is invoked from within a checkpoint
-** in wal mode before the client starts to copy pages from the wal
-** file to the database file.
-**
-**
- [[SQLITE_FCNTL_CKPT_DONE]]
-** The [SQLITE_FCNTL_CKPT_DONE] opcode is invoked from within a checkpoint
-** in wal mode after the client has finished copying pages from the wal
-** file to the database file, but before the *-shm file is updated to
-** record the fact that the pages have been checkpointed.

-** CAPI3REF: OS Interface Object
-**
-** An instance of the sqlite3_vfs object defines the interface between
-** the SQLite core and the underlying operating system. The "vfs"
-** in the name of the object stands for "virtual file system". See
-** the [VFS | VFS documentation] for further information.
-**
-** The VFS interface is sometimes extended by adding new methods onto
-** the end. Each time such an extension occurs, the iVersion field
-** is incremented. The iVersion value started out as 1 in
-** SQLite [version 3.5.0] on [dateof:3.5.0], then increased to 2
-** with SQLite [version 3.7.0] on [dateof:3.7.0], and then increased
-** to 3 with SQLite [version 3.7.6] on [dateof:3.7.6]. Additional fields
-** may be appended to the sqlite3_vfs object and the iVersion value
-** may increase again in future versions of SQLite.
-** Note that due to an oversight, the structure
-** of the sqlite3_vfs object changed in the transition from
-** SQLite [version 3.5.9] to [version 3.6.0] on [dateof:3.6.0]
-** and yet the iVersion field was not increased.
-**
-** The szOsFile field is the size of the subclassed [sqlite3_file]
-** structure used by this VFS. mxPathname is the maximum length of
-** a pathname in this VFS.
-**
-** Registered sqlite3_vfs objects are kept on a linked list formed by
-** the pNext pointer. The [sqlite3_vfs_register()]
-** and [sqlite3_vfs_unregister()] interfaces manage this list
-** in a thread-safe way. The [sqlite3_vfs_find()] interface
-** searches the list. Neither the application code nor the VFS
-** implementation should use the pNext pointer.
-**
-** The pNext field is the only field in the sqlite3_vfs
-** structure that SQLite will ever modify. SQLite will only access
-** or modify this field while holding a particular static mutex.
-** The application should never modify anything within the sqlite3_vfs
-** object once the object has been registered.
-**
-** The zName field holds the name of the VFS module. The name must
-** be unique across all VFS modules.
-**
-** [[sqlite3_vfs.xOpen]]
-** ^SQLite guarantees that the zFilename parameter to xOpen
-** is either a NULL pointer or string obtained
-** from xFullPathname() with an optional suffix added.
-** ^If a suffix is added to the zFilename parameter, it will
-** consist of a single "-" character followed by no more than
-** 11 alphanumeric and/or "-" characters.
-** ^SQLite further guarantees that
-** the string will be valid and unchanged until xClose() is
-** called. Because of the previous sentence,
-** the [sqlite3_file] can safely store a pointer to the
-** filename if it needs to remember the filename for some reason.
-** If the zFilename parameter to xOpen is a NULL pointer then xOpen
-** must invent its own temporary name for the file. ^Whenever the
-** xFilename parameter is NULL it will also be the case that the
-** flags parameter will include [SQLITE_OPEN_DELETEONCLOSE].
-**
-** The flags argument to xOpen() includes all bits set in
-** the flags argument to [sqlite3_open_v2()]. Or if [sqlite3_open()]
-** or [sqlite3_open16()] is used, then flags includes at least
-** [SQLITE_OPEN_READWRITE] | [SQLITE_OPEN_CREATE].
-** If xOpen() opens a file read-only then it sets *pOutFlags to
-** include [SQLITE_OPEN_READONLY]. Other bits in *pOutFlags may be set.
-**
-** ^(SQLite will also add one of the following flags to the xOpen()
-** call, depending on the object being opened:
-**
-**
-** - [SQLITE_OPEN_MAIN_DB]
-**
- [SQLITE_OPEN_MAIN_JOURNAL]
-**
- [SQLITE_OPEN_TEMP_DB]
-**
- [SQLITE_OPEN_TEMP_JOURNAL]
-**
- [SQLITE_OPEN_TRANSIENT_DB]
-**
- [SQLITE_OPEN_SUBJOURNAL]
-**
- [SQLITE_OPEN_SUPER_JOURNAL]
-**
- [SQLITE_OPEN_WAL]
-**
)^
-**
-** The file I/O implementation can use the object type flags to
-** change the way it deals with files. For example, an application
-** that does not care about crash recovery or rollback might make
-** the open of a journal file a no-op. Writes to this journal would
-** also be no-ops, and any attempt to read the journal would return
-** SQLITE_IOERR. Or the implementation might recognize that a database
-** file will be doing page-aligned sector reads and writes in a random
-** order and set up its I/O subsystem accordingly.
-**
-** SQLite might also add one of the following flags to the xOpen method:
-**
-**
-** - [SQLITE_OPEN_DELETEONCLOSE]
-**
- [SQLITE_OPEN_EXCLUSIVE]
-**
-**
-** The [SQLITE_OPEN_DELETEONCLOSE] flag means the file should be
-** deleted when it is closed. ^The [SQLITE_OPEN_DELETEONCLOSE]
-** will be set for TEMP databases and their journals, transient
-** databases, and subjournals.
-**
-** ^The [SQLITE_OPEN_EXCLUSIVE] flag is always used in conjunction
-** with the [SQLITE_OPEN_CREATE] flag, which are both directly
-** analogous to the O_EXCL and O_CREAT flags of the POSIX open()
-** API. The SQLITE_OPEN_EXCLUSIVE flag, when paired with the
-** SQLITE_OPEN_CREATE, is used to indicate that file should always
-** be created, and that it is an error if it already exists.
-** It is not used to indicate the file should be opened
-** for exclusive access.
-**
-** ^At least szOsFile bytes of memory are allocated by SQLite
-** to hold the [sqlite3_file] structure passed as the third
-** argument to xOpen. The xOpen method does not have to
-** allocate the structure; it should just fill it in. Note that
-** the xOpen method must set the sqlite3_file.pMethods to either
-** a valid [sqlite3_io_methods] object or to NULL. xOpen must do
-** this even if the open fails. SQLite expects that the sqlite3_file.pMethods
-** element will be valid after xOpen returns regardless of the success
-** or failure of the xOpen call.
-**
-** [[sqlite3_vfs.xAccess]]
-** ^The flags argument to xAccess() may be [SQLITE_ACCESS_EXISTS]
-** to test for the existence of a file, or [SQLITE_ACCESS_READWRITE] to
-** test whether a file is readable and writable, or [SQLITE_ACCESS_READ]
-** to test whether a file is at least readable. The SQLITE_ACCESS_READ
-** flag is never actually used and is not implemented in the built-in
-** VFSes of SQLite. The file is named by the second argument and can be a
-** directory. The xAccess method returns [SQLITE_OK] on success or some
-** non-zero error code if there is an I/O error or if the name of
-** the file given in the second argument is illegal. If SQLITE_OK
-** is returned, then non-zero or zero is written into *pResOut to indicate
-** whether or not the file is accessible.
-**
-** ^SQLite will always allocate at least mxPathname+1 bytes for the
-** output buffer xFullPathname. The exact size of the output buffer
-** is also passed as a parameter to both methods. If the output buffer
-** is not large enough, [SQLITE_CANTOPEN] should be returned. Since this is
-** handled as a fatal error by SQLite, vfs implementations should endeavor
-** to prevent this by setting mxPathname to a sufficiently large value.
-**
-** The xRandomness(), xSleep(), xCurrentTime(), and xCurrentTimeInt64()
-** interfaces are not strictly a part of the filesystem, but they are
-** included in the VFS structure for completeness.
-** The xRandomness() function attempts to return nBytes bytes
-** of good-quality randomness into zOut. The return value is
-** the actual number of bytes of randomness obtained.
-** The xSleep() method causes the calling thread to sleep for at
-** least the number of microseconds given. ^The xCurrentTime()
-** method returns a Julian Day Number for the current date and time as
-** a floating point value.
-** ^The xCurrentTimeInt64() method returns, as an integer, the Julian
-** Day Number multiplied by 86400000 (the number of milliseconds in
-** a 24-hour day).
-** ^SQLite will use the xCurrentTimeInt64() method to get the current
-** date and time if that method is available (if iVersion is 2 or
-** greater and the function pointer is not NULL) and will fall back
-** to xCurrentTime() if xCurrentTimeInt64() is unavailable.
-**
-** ^The xSetSystemCall(), xGetSystemCall(), and xNestSystemCall() interfaces
-** are not used by the SQLite core. These optional interfaces are provided
-** by some VFSes to facilitate testing of the VFS code. By overriding
-** system calls with functions under its control, a test program can
-** simulate faults and error conditions that would otherwise be difficult
-** or impossible to induce. The set of system calls that can be overridden
-** varies from one VFS to another, and from one version of the same VFS to the
-** next. Applications that use these interfaces must be prepared for any
-** or all of these interfaces to be NULL or for their behavior to change
-** from one release to the next. Applications must not attempt to access
-** any of these methods if the iVersion of the VFS is less than 3.

-** These routines are designed to aid in process initialization and

-**
-** A call to sqlite3_initialize() is an "effective" call if it is

-** All other valid calls to sqlite3_shutdown() are harmless no-ops.)^
-**
-** The sqlite3_initialize() interface is threadsafe, but sqlite3_shutdown()
-** is not. The sqlite3_shutdown() interface must only be called from a
-** single thread. All open [database connections] must be closed and all
-** other SQLite resources must be deallocated prior to invoking
-** sqlite3_shutdown().
-**
-** Among other things, ^sqlite3_initialize() will invoke
-** sqlite3_os_init(). Similarly, ^sqlite3_shutdown()
-** will invoke sqlite3_os_end().
-**
-** ^The sqlite3_initialize() routine returns [SQLITE_OK] on success.
-** ^If for some reason, sqlite3_initialize() is unable to initialize
-** the library (perhaps it is unable to allocate a needed resource such
-** as a mutex) it returns an [error code] other than [SQLITE_OK].
-**
-** ^The sqlite3_initialize() routine is called internally by many other
-** SQLite interfaces so that an application usually does not need to
-** invoke sqlite3_initialize() directly. For example, [sqlite3_open()]
-** calls sqlite3_initialize() so the SQLite library will be automatically
-** initialized when [sqlite3_open()] is called if it has not be initialized
-** already. ^However, if SQLite is compiled with the [SQLITE_OMIT_AUTOINIT]
-** compile-time option, then the automatic calls to sqlite3_initialize()
-** are omitted and the application must call sqlite3_initialize() directly
-** prior to using any other SQLite interface. For maximum portability,
-** it is recommended that applications always invoke sqlite3_initialize()
-** directly prior to using any other SQLite interface. Future releases
-** of SQLite may require this. In other words, the behavior exhibited
-** when SQLite is compiled with [SQLITE_OMIT_AUTOINIT] might become the
-** default behavior in some future release of SQLite.
-**
-** The sqlite3_os_init() routine does operating-system specific
-** initialization of the SQLite library. The sqlite3_os_end()
-** routine undoes the effect of sqlite3_os_init(). Typical tasks
-** performed by these routines include allocation or deallocation
-** of static resources, initialization of global variables,

-** A pointer to an instance of this object is the argument to
-** [sqlite3_config()] when the configuration option is

-** By creating an instance of this object
-** and passing it to [sqlite3_config]([SQLITE_CONFIG_MALLOC])
-** during configuration, an application can specify an alternative
-** memory allocation subsystem for SQLite to use for all of its
-** dynamic memory needs.
-**
-** Note that SQLite comes with several [built-in memory allocators]
-** that are perfectly adequate for the overwhelming majority of applications
-** and that this object is only useful to a tiny minority of applications
-** with specialized memory allocation requirements. This object is
-** also used during testing of SQLite in order to specify an alternative
-** memory allocator that simulates memory out-of-memory conditions in
-** order to verify that SQLite recovers gracefully from such
-** conditions.
-**
-** The xMalloc, xRealloc, and xFree methods must work like the
-** malloc(), realloc() and free() functions from the standard C library.
-** ^SQLite guarantees that the second argument to
-** xRealloc is always a value returned by a prior call to xRoundup.
-**
-** xSize should return the allocated size of a memory allocation
-** previously obtained from xMalloc or xRealloc. The allocated size
-** is always at least as big as the requested size but may be larger.
-**
-** The xRoundup method returns what would be the allocated size of
-** a memory allocation given a particular requested size. Most memory
-** allocators round up memory allocations at least to the next multiple
-** of 8. Some allocators round up to a larger multiple or to a power of 2.
-** Every memory allocation request coming in through [sqlite3_malloc()]
-** or [sqlite3_realloc()] first calls xRoundup. If xRoundup returns 0,
-** that causes the corresponding memory allocation to fail.
-**
-** The xInit method initializes the memory allocator. For example,
-** it might allocate any required mutexes or initialize internal data
-** structures. The xShutdown method is invoked (indirectly) by
-** [sqlite3_shutdown()] and should deallocate any resources acquired
-** by xInit. The pAppData pointer is used as the only parameter to

-**
-** [[SQLITE_CONFIG_MALLOC]] - SQLITE_CONFIG_MALLOC
-** - ^(The SQLITE_CONFIG_MALLOC option takes a single argument which is
-** a pointer to an instance of the [sqlite3_mem_methods] structure.
-** The argument specifies

-**
-** [[SQLITE_CONFIG_SMALL_MALLOC]] - SQLITE_CONFIG_SMALL_MALLOC
-** - ^The SQLITE_CONFIG_SMALL_MALLOC option takes single argument of
-** type int, interpreted as a boolean, which if true provides a hint to

-** - The SQLITE_CONFIG_SCRATCH option is no longer used.
-**
-**
-** [[SQLITE_CONFIG_PAGECACHE]] - SQLITE_CONFIG_PAGECACHE
-** - ^The SQLITE_CONFIG_PAGECACHE option specifies a memory pool
-** that SQLite can use for the database page cache with the default page
-** cache implementation.
-** This configuration option is a no-op if an application-defined page
-** cache implementation is loaded using the [SQLITE_CONFIG_PCACHE2].
-** ^There are three arguments to SQLITE_CONFIG_PAGECACHE: A pointer to
-** 8-byte aligned memory (pMem), the size of each page cache line (sz),
-** and the number of cache lines (N).
-** The sz argument should be the size of the largest database page
-** (a power of two between 512 and 65536) plus some extra bytes for each
-** page header. ^The number of extra bytes needed by the page header
-** can be determined using [SQLITE_CONFIG_PCACHE_HDRSZ].
-** ^It is harmless, apart from the wasted memory,
-** for the sz parameter to be larger than necessary. The pMem
-** argument must be either a NULL pointer or a pointer to an 8-byte
-** aligned block of memory of at least sz*N bytes, otherwise
-** subsequent behavior is undefined.
-** ^When pMem is not NULL, SQLite will strive to use the memory provided
-** to satisfy page cache needs, falling back to [sqlite3_malloc()] if
-** a page cache line is larger than sz bytes or if all of the pMem buffer
-** is exhausted.
-** ^If pMem is NULL and N is non-zero, then each database connection

-** ^The SQLITE_CONFIG_HEAP option is only available if SQLite is compiled
-** with either [SQLITE_ENABLE_MEMSYS3] or [SQLITE_ENABLE_MEMSYS5] and returns
-** [SQLITE_ERROR] if invoked otherwise.
-** ^There are three arguments to SQLITE_CONFIG_HEAP:
-** An 8-byte aligned pointer to the memory,
-** the number of bytes in the memory buffer, and the minimum allocation size.
-** ^If the first pointer (the memory pointer) is NULL, then SQLite reverts
-** to using its default memory allocator (the system malloc() implementation),
-** undoing any prior invocation of [SQLITE_CONFIG_MALLOC]. ^If the
-** memory pointer is not NULL then the alternative memory
-** allocator is engaged to handle all of SQLites memory allocation needs.
-** The first pointer (the memory pointer) must be aligned to an 8-byte

-**
-** [[SQLITE_CONFIG_COVERING_INDEX_SCAN]]
- SQLITE_CONFIG_COVERING_INDEX_SCAN
-**
- ^The SQLITE_CONFIG_COVERING_INDEX_SCAN option takes a single integer
-** argument which is interpreted as a boolean in order to enable or disable
-** the use of covering indices for full table scans in the query optimizer.
-** ^The default setting is determined
-** by the [SQLITE_ALLOW_COVERING_INDEX_SCAN] compile-time option, or is "on"
-** if that compile-time option is omitted.
-** The ability to disable the use of covering indices for full table scans
-** is because some incorrectly coded legacy applications might malfunction

-**
-** [[SQLITE_CONFIG_PCACHE]] [[SQLITE_CONFIG_GETPCACHE]]
-**
- SQLITE_CONFIG_PCACHE and SQLITE_CONFIG_GETPCACHE

-**
-** [[SQLITE_CONFIG_SQLLOG]]
-** - SQLITE_CONFIG_SQLLOG
-**
- This option is only available if sqlite is compiled with the
-** [SQLITE_ENABLE_SQLLOG] pre-processor macro defined. The first argument should
-** be a pointer to a function of type void(*)(void*,sqlite3*,const char*, int).
-** The second should be of type (void*). The callback is invoked by the library
-** in three separate circumstances, identified by the value passed as the
-** fourth parameter. If the fourth parameter is 0, then the database connection
-** passed as the second argument has just been opened. The third argument
-** points to a buffer containing the name of the main database file. If the
-** fourth parameter is 1, then the SQL statement that the third parameter
-** points to has just been executed. Or, if the fourth parameter is 2, then
-** the connection being passed as the second parameter is being closed. The
-** third parameter is passed NULL In this case. An example of using this

-**
-** [[SQLITE_CONFIG_MMAP_SIZE]]
-** - SQLITE_CONFIG_MMAP_SIZE
-**
- ^SQLITE_CONFIG_MMAP_SIZE takes two 64-bit integer (sqlite3_int64) values
-** that are the default mmap size limit (the default setting for
-** [PRAGMA mmap_size]) and the maximum allowed mmap size limit.
-** ^The default setting can be overridden by each database connection using
-** either the [PRAGMA mmap_size] command, or by using the

-** [[SQLITE_CONFIG_WIN32_HEAPSIZE]]
-**
- SQLITE_CONFIG_WIN32_HEAPSIZE
-**
- ^The SQLITE_CONFIG_WIN32_HEAPSIZE option is only available if SQLite is
-** compiled for Windows with the [SQLITE_WIN32_MALLOC] pre-processor macro
-** defined. ^SQLITE_CONFIG_WIN32_HEAPSIZE takes a 32-bit unsigned integer value

-**
-** [[SQLITE_CONFIG_PCACHE_HDRSZ]]
-**
- SQLITE_CONFIG_PCACHE_HDRSZ
-**
- ^The SQLITE_CONFIG_PCACHE_HDRSZ option takes a single parameter which
-** is a pointer to an integer and writes into that integer the number of extra

-** The amount of extra space required can change depending on the compiler,
-** target platform, and SQLite version.
-**
-** [[SQLITE_CONFIG_PMASZ]]
-**
- SQLITE_CONFIG_PMASZ
-**
- ^The SQLITE_CONFIG_PMASZ option takes a single parameter which
-** is an unsigned integer and sets the "Minimum PMA Size" for the multithreaded
-** sorter to that integer. The default minimum PMA Size is set by the
-** [SQLITE_SORTER_PMASZ] compile-time option. New threads are launched
-** to help with sort operations when multithreaded sorting
-** is enabled (using the [PRAGMA threads] command) and the amount of content
-** to be sorted exceeds the page size times the minimum of the
-** [PRAGMA cache_size] setting and this value.
-**
-** [[SQLITE_CONFIG_STMTJRNL_SPILL]]
-**
- SQLITE_CONFIG_STMTJRNL_SPILL
-**
- ^The SQLITE_CONFIG_STMTJRNL_SPILL option takes a single parameter which
-** becomes the [statement journal] spill-to-disk threshold.
-** [Statement journals] are held in memory until their size (in bytes)
-** exceeds this threshold, at which point they are written to disk.
-** Or if the threshold is -1, statement journals are always held
-** exclusively in memory.
-** Since many statement journals never become large, setting the spill
-** threshold to a value such as 64KiB can greatly reduce the amount of
-** I/O required to support statement rollback.
-** The default value for this setting is controlled by the
-** [SQLITE_STMTJRNL_SPILL] compile-time option.
-**
-** [[SQLITE_CONFIG_SORTERREF_SIZE]]
-**
- SQLITE_CONFIG_SORTERREF_SIZE
-**
- The SQLITE_CONFIG_SORTERREF_SIZE option accepts a single parameter
-** of type (int) - the new value of the sorter-reference size threshold.
-** Usually, when SQLite uses an external sort to order records according
-** to an ORDER BY clause, all fields required by the caller are present in the
-** sorted records. However, if SQLite determines based on the declared type
-** of a table column that its values are likely to be very large - larger
-** than the configured sorter-reference size threshold - then a reference
-** is stored in each sorted record and the required column values loaded
-** from the database as records are returned in sorted order. The default
-** value for this option is to never use this optimization. Specifying a
-** negative value for this option restores the default behaviour.
-** This option is only available if SQLite is compiled with the
-** [SQLITE_ENABLE_SORTER_REFERENCES] compile-time option.
-**
-** [[SQLITE_CONFIG_MEMDB_MAXSIZE]]
-**
- SQLITE_CONFIG_MEMDB_MAXSIZE
-**
- The SQLITE_CONFIG_MEMDB_MAXSIZE option accepts a single parameter
-** [sqlite3_int64] parameter which is the default maximum size for an in-memory
-** database created using [sqlite3_deserialize()]. This default maximum
-** size can be adjusted up or down for individual databases using the
-** [SQLITE_FCNTL_SIZE_LIMIT] [sqlite3_file_control|file-control]. If this
-** configuration setting is never used, then the default maximum is determined
-** by the [SQLITE_MEMDB_DEFAULT_MAXSIZE] compile-time option. If that
-** compile-time option is not set, then the default maximum is 1073741824.

-**
-** [[SQLITE_DBCONFIG_NO_CKPT_ON_CLOSE]]
-** - SQLITE_DBCONFIG_NO_CKPT_ON_CLOSE
-** - Usually, when a database in wal mode is closed or detached from a
-** database handle, SQLite checks if this will mean that there are now no
-** connections at all to the database. If so, it performs a checkpoint
-** operation before closing the connection. This option may be used to

-**
-**
-** [[SQLITE_DBCONFIG_TRIGGER_EQP]] - SQLITE_DBCONFIG_TRIGGER_EQP
-** - By default, the output of EXPLAIN QUERY PLAN commands does not
-** include output for any operations performed by trigger programs. This
-** option is used to set or clear (the default) a flag that governs this
-** behavior. The first parameter passed to this operation is an integer -
-** positive to enable output for trigger programs, or zero to disable it,
-** or negative to leave the setting unchanged.
-** The second parameter is a pointer to an integer into which is written
-** 0 or 1 to indicate whether output-for-triggers has been disabled - 0 if
-** it is not disabled, 1 if it is.
-**
-**
-** [[SQLITE_DBCONFIG_RESET_DATABASE]] - SQLITE_DBCONFIG_RESET_DATABASE
-** - Set the SQLITE_DBCONFIG_RESET_DATABASE flag and then run
-** [VACUUM] in order to reset a database back to an empty database
-** with no schema and no content. The following process works even for
-** a badly corrupted database file:
-**
-** - If the database connection is newly opened, make sure it has read the
-** database schema by preparing then discarding some query against the
-** database, or calling sqlite3_table_column_metadata(), ignoring any
-** errors. This step is only necessary if the application desires to keep
-** the database in WAL mode after the reset if it was in WAL mode before
-** the reset.
-**
- sqlite3_db_config(db, SQLITE_DBCONFIG_RESET_DATABASE, 1, 0);
-**
- [sqlite3_exec](db, "[VACUUM]", 0, 0, 0);
-**
- sqlite3_db_config(db, SQLITE_DBCONFIG_RESET_DATABASE, 0, 0);
-**
-** Because resetting a database is destructive and irreversible, the
-** process requires the use of this obscure API and multiple steps to help
-** ensure that it does not happen by accident.
-**
-** [[SQLITE_DBCONFIG_DEFENSIVE]] - SQLITE_DBCONFIG_DEFENSIVE
-** - The SQLITE_DBCONFIG_DEFENSIVE option activates or deactivates the
-** "defensive" flag for a database connection. When the defensive
-** flag is enabled, language features that allow ordinary SQL to
-** deliberately corrupt the database file are disabled. The disabled
-** features include but are not limited to the following:
-**
-** - The [PRAGMA writable_schema=ON] statement.
-**
- The [PRAGMA journal_mode=OFF] statement.
-**
- Writes to the [sqlite_dbpage] virtual table.
-**
- Direct writes to [shadow tables].
-**
-**
-**
-** [[SQLITE_DBCONFIG_WRITABLE_SCHEMA]] - SQLITE_DBCONFIG_WRITABLE_SCHEMA
-** - The SQLITE_DBCONFIG_WRITABLE_SCHEMA option activates or deactivates the
-** "writable_schema" flag. This has the same effect and is logically equivalent
-** to setting [PRAGMA writable_schema=ON] or [PRAGMA writable_schema=OFF].
-** The first argument to this setting is an integer which is 0 to disable
-** the writable_schema, positive to enable writable_schema, or negative to
-** leave the setting unchanged. The second parameter is a pointer to an
-** integer into which is written 0 or 1 to indicate whether the writable_schema
-** is enabled or disabled following this call.
-**
-**
-** [[SQLITE_DBCONFIG_LEGACY_ALTER_TABLE]]
-** - SQLITE_DBCONFIG_LEGACY_ALTER_TABLE
-** - The SQLITE_DBCONFIG_LEGACY_ALTER_TABLE option activates or deactivates
-** the legacy behavior of the [ALTER TABLE RENAME] command such it
-** behaves as it did prior to [version 3.24.0] (2018-06-04). See the
-** "Compatibility Notice" on the [ALTER TABLE RENAME documentation] for
-** additional information. This feature can also be turned on and off
-** using the [PRAGMA legacy_alter_table] statement.
-**
-**
-** [[SQLITE_DBCONFIG_DQS_DML]]
-** - SQLITE_DBCONFIG_DQS_DML
-**
- The SQLITE_DBCONFIG_DQS_DML option activates or deactivates
-** the legacy [double-quoted string literal] misfeature for DML statements
-** only, that is DELETE, INSERT, SELECT, and UPDATE statements. The
-** default value of this setting is determined by the [-DSQLITE_DQS]
-** compile-time option.
-**
-**
-** [[SQLITE_DBCONFIG_DQS_DDL]]
-** - SQLITE_DBCONFIG_DQS_DDL
-**
- The SQLITE_DBCONFIG_DQS option activates or deactivates
-** the legacy [double-quoted string literal] misfeature for DDL statements,
-** such as CREATE TABLE and CREATE INDEX. The
-** default value of this setting is determined by the [-DSQLITE_DQS]
-** compile-time option.
-**
-**
-** [[SQLITE_DBCONFIG_TRUSTED_SCHEMA]]
-** - SQLITE_DBCONFIG_TRUSTED_SCHEMA
-**
- The SQLITE_DBCONFIG_TRUSTED_SCHEMA option tells SQLite to
-** assume that database schemas are untainted by malicious content.
-** When the SQLITE_DBCONFIG_TRUSTED_SCHEMA option is disabled, SQLite
-** takes additional defensive steps to protect the application from harm
-** including:
-**
-** - Prohibit the use of SQL functions inside triggers, views,
-** CHECK constraints, DEFAULT clauses, expression indexes,
-** partial indexes, or generated columns
-** unless those functions are tagged with [SQLITE_INNOCUOUS].
-**
- Prohibit the use of virtual tables inside of triggers or views
-** unless those virtual tables are tagged with [SQLITE_VTAB_INNOCUOUS].
-**
-** This setting defaults to "on" for legacy compatibility, however
-** all applications are advised to turn it off if possible. This setting
-** can also be controlled using the [PRAGMA trusted_schema] statement.
-**
-**
-** [[SQLITE_DBCONFIG_LEGACY_FILE_FORMAT]]
-** - SQLITE_DBCONFIG_LEGACY_FILE_FORMAT
-**
- The SQLITE_DBCONFIG_LEGACY_FILE_FORMAT option activates or deactivates
-** the legacy file format flag. When activated, this flag causes all newly
-** created database file to have a schema format version number (the 4-byte
-** integer found at offset 44 into the database header) of 1. This in turn
-** means that the resulting database file will be readable and writable by
-** any SQLite version back to 3.0.0 ([dateof:3.0.0]). Without this setting,
-** newly created databases are generally not understandable by SQLite versions
-** prior to 3.3.0 ([dateof:3.3.0]). As these words are written, there
-** is now scarcely any need to generated database files that are compatible
-** all the way back to version 3.0.0, and so this setting is of little
-** practical use, but is provided so that SQLite can continue to claim the
-** ability to generate new database files that are compatible with version
-** 3.0.0.
-**
Note that when the SQLITE_DBCONFIG_LEGACY_FILE_FORMAT setting is on,
-** the [VACUUM] command will fail with an obscure error when attempting to
-** process a table with generated columns and a descending index. This is
-** not considered a bug since SQLite versions 3.3.0 and earlier do not support
-** either generated columns or decending indexes.

-** CAPI3REF: Convenience Routines For Running Queries
-** METHOD: sqlite3
-**
-** This is a legacy interface that is preserved for backwards compatibility.
-** Use of this interface is not recommended.
-**
-** Definition: A result table is memory data structure created by the
-** [sqlite3_get_table()] interface. A result table records the
-** complete query results from one or more queries.
-**
-** The table conceptually has a number of rows and columns. But
-** these numbers are not part of the result table itself. These
-** numbers are obtained separately. Let N be the number of rows
-** and M be the number of columns.
-**
-** A result table is an array of pointers to zero-terminated UTF-8 strings.
-** There are (N+1)*M elements in the array. The first M pointers point
-** to zero-terminated strings that contain the names of the columns.
-** The remaining entries all point to query results. NULL values result
-** in NULL pointers. All other values are in their UTF-8 zero-terminated
-** string representation as returned by [sqlite3_column_text()].
-**
-** A result table might consist of one or more memory allocations.
-** It is not safe to pass a result table directly to [sqlite3_free()].
-** A result table should be deallocated using [sqlite3_free_table()].
-**
-** ^(As an example of the result table format, suppose a query result
-** is as follows:
-**
-**
-** Name | Age
-** -----------------------
-** Alice | 43
-** Bob | 28
-** Cindy | 21
-**
-**
-** There are two columns (M==2) and three rows (N==3). Thus the
-** result table has 8 entries. Suppose the result table is stored
-** in an array named azResult. Then azResult holds this content:
-**
-**
-** azResult[0] = "Name";
-** azResult[1] = "Age";
-** azResult[2] = "Alice";
-** azResult[3] = "43";
-** azResult[4] = "Bob";
-** azResult[5] = "28";
-** azResult[6] = "Cindy";
-** azResult[7] = "21";
-** )^
-**
-** ^The sqlite3_get_table() function evaluates one or more
-** semicolon-separated SQL statements in the zero-terminated UTF-8
-** string of its 2nd parameter and returns a result table to the
-** pointer given in its 3rd parameter.
-**
-** After the application has finished with the result from sqlite3_get_table(),
-** it must pass the result table pointer to sqlite3_free_table() in order to
-** release the memory that was malloced. Because of the way the
-** [sqlite3_malloc()] happens within sqlite3_get_table(), the calling
-** function must not try to call [sqlite3_free()] directly. Only
-** [sqlite3_free_table()] is able to release the memory properly and safely.
-**
-** The sqlite3_get_table() interface is implemented as a wrapper around

-** CAPI3REF: Memory Allocation Subsystem
-**
-** The SQLite core uses these three routines for all of its own
-** internal memory allocation needs. "Core" in the previous sentence
-** does not include operating-system specific [VFS] implementation. The
-** Windows VFS uses native malloc() and free() for some operations.
-**
-** ^The sqlite3_malloc() routine returns a pointer to a block
-** of memory at least N bytes in length, where N is the parameter.
-** ^If sqlite3_malloc() is unable to obtain sufficient free
-** memory, it returns a NULL pointer. ^If the parameter N to
-** sqlite3_malloc() is zero or negative then sqlite3_malloc() returns
-** a NULL pointer.
-**
-** ^The sqlite3_malloc64(N) routine works just like
-** sqlite3_malloc(N) except that N is an unsigned 64-bit integer instead
-** of a signed 32-bit integer.
-**
-** ^Calling sqlite3_free() with a pointer previously returned
-** by sqlite3_malloc() or sqlite3_realloc() releases that memory so
-** that it might be reused. ^The sqlite3_free() routine is
-** a no-op if is called with a NULL pointer. Passing a NULL pointer
-** to sqlite3_free() is harmless. After being freed, memory
-** should neither be read nor written. Even reading previously freed
-** memory might result in a segmentation fault or other severe error.
-** Memory corruption, a segmentation fault, or other severe error
-** might result if sqlite3_free() is called with a non-NULL pointer that
-** was not obtained from sqlite3_malloc() or sqlite3_realloc().
-**
-** ^The sqlite3_realloc(X,N) interface attempts to resize a
-** prior memory allocation X to be at least N bytes.
-** ^If the X parameter to sqlite3_realloc(X,N)
-** is a NULL pointer then its behavior is identical to calling
-** sqlite3_malloc(N).
-** ^If the N parameter to sqlite3_realloc(X,N) is zero or
-** negative then the behavior is exactly the same as calling
-** sqlite3_free(X).
-** ^sqlite3_realloc(X,N) returns a pointer to a memory allocation
-** of at least N bytes in size or NULL if insufficient memory is available.
-** ^If M is the size of the prior allocation, then min(N,M) bytes
-** of the prior allocation are copied into the beginning of buffer returned
-** by sqlite3_realloc(X,N) and the prior allocation is freed.
-** ^If sqlite3_realloc(X,N) returns NULL and N is positive, then the
-** prior allocation is not freed.
-**
-** ^The sqlite3_realloc64(X,N) interfaces works the same as
-** sqlite3_realloc(X,N) except that N is a 64-bit unsigned integer instead
-** of a 32-bit signed integer.
-**
-** ^If X is a memory allocation previously obtained from sqlite3_malloc(),
-** sqlite3_malloc64(), sqlite3_realloc(), or sqlite3_realloc64(), then
-** sqlite3_msize(X) returns the size of that memory allocation in bytes.
-** ^The value returned by sqlite3_msize(X) might be larger than the number
-** of bytes requested when X was allocated. ^If X is a NULL pointer then
-** sqlite3_msize(X) returns zero. If X points to something that is not
-** the beginning of memory allocation, or if it points to a formerly
-** valid memory allocation that has now been freed, then the behavior
-** of sqlite3_msize(X) is undefined and possibly harmful.
-**
-** ^The memory returned by sqlite3_malloc(), sqlite3_realloc(),
-** sqlite3_malloc64(), and sqlite3_realloc64()
-** is always aligned to at least an 8 byte boundary, or to a
-** 4 byte boundary if the [SQLITE_4_BYTE_ALIGNED_MALLOC] compile-time
-** option is used.
-**
-** The pointer arguments to [sqlite3_free()] and [sqlite3_realloc()]

-** METHOD: sqlite3
-** KEYWORDS: {authorizer callback}
-**
-** ^This routine registers an authorizer callback with a particular
-** [database connection], supplied in the first argument.
-** ^The authorizer callback is invoked as SQL statements are being compiled
-** by [sqlite3_prepare()] or its variants [sqlite3_prepare_v2()],
-** [sqlite3_prepare_v3()], [sqlite3_prepare16()], [sqlite3_prepare16_v2()],
-** and [sqlite3_prepare16_v3()]. ^At various
-** points during the compilation process, as logic is being created
-** to perform various actions, the authorizer callback is invoked to
-** see if those actions are allowed. ^The authorizer callback should
-** return [SQLITE_OK] to allow the action, [SQLITE_IGNORE] to disallow the
-** specific action but allow the SQL statement to continue to be
-** compiled, or [SQLITE_DENY] to cause the entire SQL statement to be
-** rejected with an error. ^If the authorizer callback returns
-** any value other than [SQLITE_IGNORE], [SQLITE_OK], or [SQLITE_DENY]
-** then the [sqlite3_prepare_v2()] or equivalent call that triggered
-** the authorizer will fail with an error message.
-**
-** When the callback returns [SQLITE_OK], that means the operation
-** requested is ok. ^When the callback returns [SQLITE_DENY], the
-** [sqlite3_prepare_v2()] or equivalent call that triggered the
-** authorizer will fail with an error message explaining that
-** access is denied.
-**
-** ^The first parameter to the authorizer callback is a copy of the third
-** parameter to the sqlite3_set_authorizer() interface. ^The second parameter
-** to the callback is an integer [SQLITE_COPY | action code] that specifies
-** the particular action to be authorized. ^The third through sixth parameters
-** to the callback are either NULL pointers or zero-terminated strings
-** that contain additional details about the action to be authorized.
-** Applications must always be prepared to encounter a NULL pointer in any
-** of the third through the sixth parameters of the authorization callback.
-**
-** ^If the action code is [SQLITE_READ]
-** and the callback returns [SQLITE_IGNORE] then the
-** [prepared statement] statement is constructed to substitute
-** a NULL value in place of the table column that would have
-** been read if [SQLITE_OK] had been returned. The [SQLITE_IGNORE]
-** return can be used to deny an untrusted user access to individual
-** columns of a table.
-** ^When a table is referenced by a [SELECT] but no column values are
-** extracted from that table (for example in a query like
-** "SELECT count(*) FROM tab") then the [SQLITE_READ] authorizer callback
-** is invoked once for that table with a column name that is an empty string.
-** ^If the action code is [SQLITE_DELETE] and the callback returns
-** [SQLITE_IGNORE] then the [DELETE] operation proceeds but the
-** [truncate optimization] is disabled and all rows are deleted individually.
-**
-** An authorizer is used when [sqlite3_prepare | preparing]
-** SQL statements from an untrusted source, to ensure that the SQL statements
-** do not try to access data they are not allowed to see, or that they do not
-** try to execute malicious statements that damage the database. For
-** example, an application may allow a user to enter arbitrary
-** SQL queries for evaluation by a database. But the application does
-** not want the user to be able to make arbitrary changes to the
-** database. An authorizer could then be put in place while the
-** user-entered SQL is being [sqlite3_prepare | prepared] that
-** disallows everything except [SELECT] statements.
-**
-** Applications that need to process SQL from untrusted sources
-** might also consider lowering resource limits using [sqlite3_limit()]
-** and limiting database size using the [max_page_count] [PRAGMA]
-** in addition to using an authorizer.
-**
-** ^(Only a single authorizer can be in place on a database connection
-** at a time. Each call to sqlite3_set_authorizer overrides the
-** previous call.)^ ^Disable the authorizer by installing a NULL callback.
-** The authorizer is disabled by default.

-** statement might be re-prepared during [sqlite3_step()] due to a
-** schema change. Hence, the application should ensure that the
-** correct authorizer callback remains in place during the [sqlite3_step()].
-**
-** ^Note that the authorizer callback is invoked only during
-** [sqlite3_prepare()] or its variants. Authorization is not
-** performed during statement evaluation in [sqlite3_step()], unless

-** [[URI filenames in sqlite3_open()]] URI Filenames
-**
-** ^If [URI filename] interpretation is enabled, and the filename argument

-** filename interpretation is enabled if the [SQLITE_OPEN_URI] flag is
-** set in the third argument to sqlite3_open_v2(), or if it has
-** been enabled globally using the [SQLITE_CONFIG_URI] option with the
-** [sqlite3_config()] method or by the [SQLITE_USE_URI] compile-time option.
-** URI filename interpretation is turned off
-** by default, but future releases of SQLite might enable URI filename
-** interpretation by default. See "[URI filenames]" for additional
-** information.
-**
-** URI filenames are parsed according to RFC 3986. ^If the URI contains an
-** authority, then it must be either an empty string or the string
-** "localhost". ^If the authority is not an empty string or "localhost", an
-** error is returned to the caller. ^The fragment component of a URI, if
-** present, is ignored.
-**
-** ^SQLite uses the path component of the URI as the name of the disk file
-** which contains the database. ^If the path begins with a '/' character,
-** then it is interpreted as an absolute path. ^If the path does not begin
-** with a '/' (meaning that the authority section is omitted from the URI)
-** then the path is interpreted as a relative path.
-** ^(On windows, the first component of an absolute path
-** is a drive specification (e.g. "C:").)^
-**
-** [[core URI query parameters]]
-** The query component of a URI may contain parameters that are interpreted
-** either by SQLite itself, or by a [VFS | custom VFS implementation].
-** SQLite and its built-in [VFSes] interpret the
-** following query parameters:
-**
-**
-** - vfs: ^The "vfs" parameter may be used to specify the name of
-** a VFS object that provides the operating system interface that should
-** be used to access the database file on disk. ^If this option is set to
-** an empty string the default VFS object is used. ^Specifying an unknown
-** VFS is an error. ^If sqlite3_open_v2() is used and the vfs option is
-** present, then the VFS specified by the option takes precedence over
-** the value passed as the fourth parameter to sqlite3_open_v2().
-**
-**
- mode: ^(The mode parameter may be set to either "ro", "rw",
-** "rwc", or "memory". Attempting to set it to any other value is
-** an error)^.
-** ^If "ro" is specified, then the database is opened for read-only
-** access, just as if the [SQLITE_OPEN_READONLY] flag had been set in the
-** third argument to sqlite3_open_v2(). ^If the mode option is set to
-** "rw", then the database is opened for read-write (but not create)
-** access, as if SQLITE_OPEN_READWRITE (but not SQLITE_OPEN_CREATE) had
-** been set. ^Value "rwc" is equivalent to setting both
-** SQLITE_OPEN_READWRITE and SQLITE_OPEN_CREATE. ^If the mode option is
-** set to "memory" then a pure [in-memory database] that never reads
-** or writes from disk is used. ^It is an error to specify a value for
-** the mode parameter that is less restrictive than that specified by
-** the flags passed in the third parameter to sqlite3_open_v2().
-**
-**
- cache: ^The cache parameter may be set to either "shared" or
-** "private". ^Setting it to "shared" is equivalent to setting the
-** SQLITE_OPEN_SHAREDCACHE bit in the flags argument passed to
-** sqlite3_open_v2(). ^Setting the cache parameter to "private" is
-** equivalent to setting the SQLITE_OPEN_PRIVATECACHE bit.
-** ^If sqlite3_open_v2() is used and the "cache" parameter is present in
-** a URI filename, its value overrides any behavior requested by setting
-** SQLITE_OPEN_PRIVATECACHE or SQLITE_OPEN_SHAREDCACHE flag.
-**
-**
- psow: ^The psow parameter indicates whether or not the
-** [powersafe overwrite] property does or does not apply to the
-** storage media on which the database file resides.
-**
-**
- nolock: ^The nolock parameter is a boolean query parameter
-** which if set disables file locking in rollback journal modes. This
-** is useful for accessing a database on a filesystem that does not
-** support locking. Caution: Database corruption might result if two
-** or more processes write to the same database and any one of those
-** processes uses nolock=1.
-**
-**
- immutable: ^The immutable parameter is a boolean query
-** parameter that indicates that the database file is stored on
-** read-only media. ^When immutable is set, SQLite assumes that the
-** database file cannot be changed, even by a process with higher
-** privilege, and so the database is opened read-only and all locking
-** and change detection is disabled. Caution: Setting the immutable
-** property on a database file that does in fact change can result
-** in incorrect query results and/or [SQLITE_CORRUPT] errors.
-** See also: [SQLITE_IOCAP_IMMUTABLE].
-**
-**
-**
-** ^Specifying an unknown parameter in the query component of a URI is not an
-** error. Future versions of SQLite might understand additional query
-** parameters. See "[query parameters with special meaning to SQLite]" for
-** additional information.

-** CAPI3REF: Obtain Values For URI Parameters
-**
-** These are utility routines, useful to [VFS|custom VFS implementations],
-** that check if a database file was a URI that contained a specific query
-** parameter, and if so obtains the value of that query parameter.
-**
-** The first parameter to these interfaces (hereafter referred to
-** as F) must be one of:
-**
-** - A database filename pointer created by the SQLite core and
-** passed into the xOpen() method of a VFS implemention, or
-**
- A filename obtained from [sqlite3_db_filename()], or
-**
- A new filename constructed using [sqlite3_create_filename()].
-**
-** If the F parameter is not one of the above, then the behavior is
-** undefined and probably undesirable. Older versions of SQLite were
-** more tolerant of invalid F parameters than newer versions.
-**
-** If F is a suitable filename (as described in the previous paragraph)
-** and if P is the name of the query parameter, then
-** sqlite3_uri_parameter(F,P) returns the value of the P
-** parameter if it exists or a NULL pointer if P does not appear as a
-** query parameter on F. If P is a query parameter of F and it
-** has no explicit value, then sqlite3_uri_parameter(F,P) returns
-** a pointer to an empty string.
-**
-** The sqlite3_uri_boolean(F,P,B) routine assumes that P is a boolean
-** parameter and returns true (1) or false (0) according to the value
-** of P. The sqlite3_uri_boolean(F,P,B) routine returns true (1) if the
-** value of query parameter P is one of "yes", "true", or "on" in any
-** case or if the value begins with a non-zero number. The
-** sqlite3_uri_boolean(F,P,B) routines returns false (0) if the value of
-** query parameter P is one of "no", "false", or "off" in any case or
-** if the value begins with a numeric zero. If P is not a query
-** parameter on F or if the value of P does not match any of the
-** above, then sqlite3_uri_boolean(F,P,B) returns (B!=0).
-**
-** The sqlite3_uri_int64(F,P,D) routine converts the value of P into a
-** 64-bit signed integer and returns that integer, or D if P does not
-** exist. If the value of P is something other than an integer, then
-** zero is returned.
-**
-** The sqlite3_uri_key(F,N) returns a pointer to the name (not
-** the value) of the N-th query parameter for filename F, or a NULL
-** pointer if N is less than zero or greater than the number of query
-** parameters minus 1. The N value is zero-based so N should be 0 to obtain
-** the name of the first query parameter, 1 for the second parameter, and
-** so forth.
-**
-** If F is a NULL pointer, then sqlite3_uri_parameter(F,P) returns NULL and
-** sqlite3_uri_boolean(F,P,B) returns B. If F is not a NULL pointer and
-** is not a database file pathname pointer that the SQLite core passed
-** into the xOpen VFS method, then the behavior of this routine is undefined
-** and probably undesirable.
-**
-** Beginning with SQLite [version 3.31.0] ([dateof:3.31.0]) the input F
-** parameter can also be the name of a rollback journal file or WAL file
-** in addition to the main database file. Prior to version 3.31.0, these
-** routines would only work if F was the name of the main database file.
-** When the F parameter is the name of the rollback journal or WAL file,
-** it has access to all the same query parameters as were found on the
-** main database file.

-** CAPI3REF: Compiling An SQL Statement
-** KEYWORDS: {SQL statement compiler}
-** METHOD: sqlite3
-** CONSTRUCTOR: sqlite3_stmt
-**
-** To execute an SQL statement, it must first be compiled into a byte-code
-** program using one of these routines. Or, in other words, these routines
-** are constructors for the [prepared statement] object.
-**
-** The preferred routine to use is [sqlite3_prepare_v2()]. The
-** [sqlite3_prepare()] interface is legacy and should be avoided.
-** [sqlite3_prepare_v3()] has an extra "prepFlags" option that is used
-** for special purposes.
-**
-** The use of the UTF-8 interfaces is preferred, as SQLite currently
-** does all parsing using UTF-8. The UTF-16 interfaces are provided
-** as a convenience. The UTF-16 interfaces work by converting the
-** input text into UTF-8, then invoking the corresponding UTF-8 interface.
-**
-** The first argument, "db", is a [database connection] obtained from a
-** prior successful call to [sqlite3_open()], [sqlite3_open_v2()] or
-** [sqlite3_open16()]. The database connection must not have been closed.
-**
-** The second argument, "zSql", is the statement to be compiled, encoded
-** as either UTF-8 or UTF-16. The sqlite3_prepare(), sqlite3_prepare_v2(),
-** and sqlite3_prepare_v3()
-** interfaces use UTF-8, and sqlite3_prepare16(), sqlite3_prepare16_v2(),
-** and sqlite3_prepare16_v3() use UTF-16.
-**
-** ^If the nByte argument is negative, then zSql is read up to the
-** first zero terminator. ^If nByte is positive, then it is the
-** number of bytes read from zSql. ^If nByte is zero, then no prepared
-** statement is generated.
-** If the caller knows that the supplied string is nul-terminated, then
-** there is a small performance advantage to passing an nByte parameter that
-** is the number of bytes in the input string including
-** the nul-terminator.
-**
-** ^If pzTail is not NULL then *pzTail is made to point to the first byte
-** past the end of the first SQL statement in zSql. These routines only
-** compile the first statement in zSql, so *pzTail is left pointing to
-** what remains uncompiled.
-**
-** ^*ppStmt is left pointing to a compiled [prepared statement] that can be
-** executed using [sqlite3_step()]. ^If there is an error, *ppStmt is set
-** to NULL. ^If the input text contains no SQL (if the input is an empty
-** string or a comment) then *ppStmt is set to NULL.
-** The calling procedure is responsible for deleting the compiled
-** SQL statement using [sqlite3_finalize()] after it has finished with it.
-** ppStmt may not be NULL.
-**
-** ^On success, the sqlite3_prepare() family of routines return [SQLITE_OK];
-** otherwise an [error code] is returned.
-**
-** The sqlite3_prepare_v2(), sqlite3_prepare_v3(), sqlite3_prepare16_v2(),
-** and sqlite3_prepare16_v3() interfaces are recommended for all new programs.
-** The older interfaces (sqlite3_prepare() and sqlite3_prepare16())
-** are retained for backwards compatibility, but their use is discouraged.
-** ^In the "vX" interfaces, the prepared statement
-** that is returned (the [sqlite3_stmt] object) contains a copy of the
-** original SQL text. This causes the [sqlite3_step()] interface to
-** behave differently in three ways:
-**
-**
-** -
-** ^If the database schema changes, instead of returning [SQLITE_SCHEMA] as it
-** always used to do, [sqlite3_step()] will automatically recompile the SQL
-** statement and try to run it again. As many as [SQLITE_MAX_SCHEMA_RETRY]
-** retries will occur before sqlite3_step() gives up and returns an error.
-**
-**
-** -
-** ^When an error occurs, [sqlite3_step()] will return one of the detailed
-** [error codes] or [extended error codes]. ^The legacy behavior was that
-** [sqlite3_step()] would only return a generic [SQLITE_ERROR] result code
-** and the application would have to make a second call to [sqlite3_reset()]
-** in order to find the underlying cause of the problem. With the "v2" prepare
-** interfaces, the underlying reason for the error is returned immediately.
-**
-**
-** -
-** ^If the specific value bound to a [parameter | host parameter] in the
-** WHERE clause might influence the choice of query plan for a statement,
-** then the statement will be automatically recompiled, as if there had been
-** a schema change, on the first [sqlite3_step()] call following any change
-** to the [sqlite3_bind_text | bindings] of that [parameter].
-** ^The specific value of a WHERE-clause [parameter] might influence the
-** choice of query plan if the parameter is the left-hand side of a [LIKE]
-** or [GLOB] operator or if the parameter is compared to an indexed column
-** and the [SQLITE_ENABLE_STAT4] compile-time option is enabled.
-**
-**
-**
-** ^sqlite3_prepare_v3() differs from sqlite3_prepare_v2() only in having
-** the extra prepFlags parameter, which is a bit array consisting of zero or
-** more of the [SQLITE_PREPARE_PERSISTENT|SQLITE_PREPARE_*] flags. ^The
-** sqlite3_prepare_v2() interface works exactly the same as
-** sqlite3_prepare_v3() with a zero prepFlags parameter.

-** [sqlite3_prepare_v3()], [sqlite3_prepare_v2()], [sqlite3_prepare16_v3()],

-** interfaces [sqlite3_prepare()] and [sqlite3_prepare16()]. The use of the

-**
-** ^In the legacy interface, the return value will be either [SQLITE_BUSY],
-** [SQLITE_DONE], [SQLITE_ROW], [SQLITE_ERROR], or [SQLITE_MISUSE].
-** ^With the "v2" interface, any of the other [result codes] or
-** [extended result codes] might be returned as well.
-**
-** ^[SQLITE_BUSY] means that the database engine was unable to acquire the
-** database locks it needs to do its job. ^If the statement is a [COMMIT]
-** or occurs outside of an explicit transaction, then you can retry the
-** statement. If the statement is not a [COMMIT] and occurs within an
-** explicit transaction then you should rollback the transaction before
-** continuing.
-**
-** ^[SQLITE_DONE] means that the statement has finished executing
-** successfully. sqlite3_step() should not be called again on this virtual
-** machine without first calling [sqlite3_reset()] to reset the virtual
-** machine back to its initial state.
-**
-** ^If the SQL statement being executed returns any data, then [SQLITE_ROW]
-** is returned each time a new row of data is ready for processing by the
-** caller. The values may be accessed using the [column access functions].
-** sqlite3_step() is called again to retrieve the next row of data.
-**
-** ^[SQLITE_ERROR] means that a run-time error (such as a constraint
-** violation) has occurred. sqlite3_step() should not be called again on
-** the VM. More information may be found by calling [sqlite3_errmsg()].
-** ^With the legacy interface, a more specific error code (for example,
-** [SQLITE_INTERRUPT], [SQLITE_SCHEMA], [SQLITE_CORRUPT], and so forth)
-** can be obtained by calling [sqlite3_reset()] on the
-** [prepared statement]. ^In the "v2" interface,
-** the more specific error code is returned directly by sqlite3_step().
-**
-** [SQLITE_MISUSE] means that the this routine was called inappropriately.
-** Perhaps it was called on a [prepared statement] that has
-** already been [sqlite3_finalize | finalized] or on one that had
-** previously returned [SQLITE_ERROR] or [SQLITE_DONE]. Or it could
-** be the case that the same database connection is being used by two or
-** more threads at the same moment in time.
-**
-** For all versions of SQLite up to and including 3.6.23.1, a call to
-** [sqlite3_reset()] was required after sqlite3_step() returned anything
-** other than [SQLITE_ROW] before any subsequent invocation of
-** sqlite3_step(). Failure to reset the prepared statement using
-** [sqlite3_reset()] would result in an [SQLITE_MISUSE] return from
-** sqlite3_step(). But after [version 3.6.23.1] ([dateof:3.6.23.1],
-** sqlite3_step() began
-** calling [sqlite3_reset()] automatically in this circumstance rather
-** than returning [SQLITE_MISUSE]. This is not considered a compatibility
-** break because any application that ever receives an SQLITE_MISUSE error
-** is broken by definition. The [SQLITE_OMIT_AUTORESET] compile-time option
-** can be used to restore the legacy behavior.
-**
-** Goofy Interface Alert: In the legacy interface, the sqlite3_step()
-** API always returns a generic error code, [SQLITE_ERROR], following any
-** error other than [SQLITE_BUSY] and [SQLITE_MISUSE]. You must call
-** [sqlite3_reset()] or [sqlite3_finalize()] in order to find one of the
-** specific [error codes] that better describes the error.
-** We admit that this is a goofy design. The problem has been fixed
-** with the "v2" interface. If you prepare all of your SQL statements
-** using [sqlite3_prepare_v3()] or [sqlite3_prepare_v2()]
-** or [sqlite3_prepare16_v2()] or [sqlite3_prepare16_v3()] instead

-** Details:

-** ^These routines return information about a single column of the current
-** result row of a query. ^In every case the first argument is a pointer
-** to the [prepared statement] that is being evaluated (the [sqlite3_stmt*]
-** that was returned from [sqlite3_prepare_v2()] or one of its variants)
-** and the second argument is the index of the column for which information
-** should be returned. ^The leftmost column of the result set has the index 0.
-** ^The number of columns in the result can be determined using
-** [sqlite3_column_count()].
-**
-** If the SQL statement does not currently point to a valid row, or if the
-** column index is out of range, the result is undefined.
-** These routines may only be called when the most recent call to
-** [sqlite3_step()] has returned [SQLITE_ROW] and neither
-** [sqlite3_reset()] nor [sqlite3_finalize()] have been called subsequently.
-** If any of these routines are called after [sqlite3_reset()] or
-** [sqlite3_finalize()] or after [sqlite3_step()] has returned
-** something other than [SQLITE_ROW], the results are undefined.
-** If [sqlite3_step()] or [sqlite3_reset()] or [sqlite3_finalize()]
-** are called from a different thread while any of these routines
-** are pending, then the results are undefined.
-**
-** The first six interfaces (_blob, _double, _int, _int64, _text, and _text16)
-** each return the value of a result column in a specific data format. If
-** the result column is not initially in the requested format (for example,
-** if the query returns an integer but the sqlite3_column_text() interface
-** is used to extract the value) then an automatic type conversion is performed.
-**
-** ^The sqlite3_column_type() routine returns the
-** [SQLITE_INTEGER | datatype code] for the initial data type
-** of the result column. ^The returned value is one of [SQLITE_INTEGER],
-** [SQLITE_FLOAT], [SQLITE_TEXT], [SQLITE_BLOB], or [SQLITE_NULL].
-** The return value of sqlite3_column_type() can be used to decide which
-** of the first six interface should be used to extract the column value.
-** The value returned by sqlite3_column_type() is only meaningful if no
-** automatic type conversions have occurred for the value in question.
-** After a type conversion, the result of calling sqlite3_column_type()
-** is undefined, though harmless. Future
-** versions of SQLite may change the behavior of sqlite3_column_type()
-** following a type conversion.
-**
-** If the result is a BLOB or a TEXT string, then the sqlite3_column_bytes()
-** or sqlite3_column_bytes16() interfaces can be used to determine the size
-** of that BLOB or string.
-**
-** ^If the result is a BLOB or UTF-8 string then the sqlite3_column_bytes()
-** routine returns the number of bytes in that BLOB or string.
-** ^If the result is a UTF-16 string, then sqlite3_column_bytes() converts
-** the string to UTF-8 and then returns the number of bytes.
-** ^If the result is a numeric value then sqlite3_column_bytes() uses
-** [sqlite3_snprintf()] to convert that value to a UTF-8 string and returns
-** the number of bytes in that string.
-** ^If the result is NULL, then sqlite3_column_bytes() returns zero.
-**
-** ^If the result is a BLOB or UTF-16 string then the sqlite3_column_bytes16()
-** routine returns the number of bytes in that BLOB or string.
-** ^If the result is a UTF-8 string, then sqlite3_column_bytes16() converts
-** the string to UTF-16 and then returns the number of bytes.
-** ^If the result is a numeric value then sqlite3_column_bytes16() uses
-** [sqlite3_snprintf()] to convert that value to a UTF-16 string and returns
-** the number of bytes in that string.
-** ^If the result is NULL, then sqlite3_column_bytes16() returns zero.
-**
-** ^The values returned by [sqlite3_column_bytes()] and
-** [sqlite3_column_bytes16()] do not include the zero terminators at the end
-** of the string. ^For clarity: the values returned by
-** [sqlite3_column_bytes()] and [sqlite3_column_bytes16()] are the number of
-** bytes in the string, not the number of characters.
-**
-** ^Strings returned by sqlite3_column_text() and sqlite3_column_text16(),
-** even empty strings, are always zero-terminated. ^The return
-** value from sqlite3_column_blob() for a zero-length BLOB is a NULL pointer.
-**
-** Warning: ^The object returned by [sqlite3_column_value()] is an
-** [unprotected sqlite3_value] object. In a multithreaded environment,
-** an unprotected sqlite3_value object may only be used safely with
-** [sqlite3_bind_value()] and [sqlite3_result_value()].
-** If the [unprotected sqlite3_value] object returned by
-** [sqlite3_column_value()] is used in any other way, including calls
-** to routines like [sqlite3_value_int()], [sqlite3_value_text()],
-** or [sqlite3_value_bytes()], the behavior is not threadsafe.
-** Hence, the sqlite3_column_value() interface
-** is normally only useful within the implementation of
-** [application-defined SQL functions] or [virtual tables], not within
-** top-level application code.
-**
-** The these routines may attempt to convert the datatype of the result.
-** ^For example, if the internal representation is FLOAT and a text result
-** is requested, [sqlite3_snprintf()] is used internally to perform the
-** conversion automatically. ^(The following table details the conversions
-** that are applied:
-**
-**
-**
-** Internal Type | Requested Type | Conversion
-**
-** |
|---|
| NULL | INTEGER | Result is 0
-** | | NULL | FLOAT | Result is 0.0
-** | | NULL | TEXT | Result is a NULL pointer
-** | | NULL | BLOB | Result is a NULL pointer
-** | | INTEGER | FLOAT | Convert from integer to float
-** | | INTEGER | TEXT | ASCII rendering of the integer
-** | | INTEGER | BLOB | Same as INTEGER->TEXT
-** | | FLOAT | INTEGER | [CAST] to INTEGER
-** | | FLOAT | TEXT | ASCII rendering of the float
-** | | FLOAT | BLOB | [CAST] to BLOB
-** | | TEXT | INTEGER | [CAST] to INTEGER
-** | | TEXT | FLOAT | [CAST] to REAL
-** | | TEXT | BLOB | No change
-** | | BLOB | INTEGER | [CAST] to INTEGER
-** | | BLOB | FLOAT | [CAST] to REAL
-** | | BLOB | TEXT | Add a zero terminator if needed
-** |
-** )^
-**
-** Note that when type conversions occur, pointers returned by prior
-** calls to sqlite3_column_blob(), sqlite3_column_text(), and/or
-** sqlite3_column_text16() may be invalidated.
-** Type conversions and pointer invalidations might occur
-** in the following cases:
-**
-**
-** - The initial content is a BLOB and sqlite3_column_text() or
-** sqlite3_column_text16() is called. A zero-terminator might
-** need to be added to the string.
-** - The initial content is UTF-8 text and sqlite3_column_bytes16() or
-** sqlite3_column_text16() is called. The content must be converted
-** to UTF-16.
-** - The initial content is UTF-16 text and sqlite3_column_bytes() or
-** sqlite3_column_text() is called. The content must be converted
-** to UTF-8.
-**
-**
-** ^Conversions between UTF-16be and UTF-16le are always done in place and do
-** not invalidate a prior pointer, though of course the content of the buffer
-** that the prior pointer references will have been modified. Other kinds
-** of conversion are done in place when it is possible, but sometimes they
-** are not possible and in those cases prior pointers are invalidated.
-**
-** The safest policy is to invoke these routines
-** in one of the following ways:
-**
-**
-** - sqlite3_column_text() followed by sqlite3_column_bytes()
-** - sqlite3_column_blob() followed by sqlite3_column_bytes()
-** - sqlite3_column_text16() followed by sqlite3_column_bytes16()
-**
-**
-** In other words, you should call sqlite3_column_text(),
-** sqlite3_column_blob(), or sqlite3_column_text16() first to force the result
-** into the desired format, then invoke sqlite3_column_bytes() or
-** sqlite3_column_bytes16() to find the size of the result. Do not mix calls
-** to sqlite3_column_text() or sqlite3_column_blob() with calls to
-** sqlite3_column_bytes16(), and do not mix calls to sqlite3_column_text16()
-** with calls to sqlite3_column_bytes().
-**
-** ^The pointers returned are valid until a type conversion occurs as
-** described above, or until [sqlite3_step()] or [sqlite3_reset()] or
-** [sqlite3_finalize()] is called. ^The memory space used to hold strings
-** and BLOBs is freed automatically. Do not pass the pointers returned
-** from [sqlite3_column_blob()], [sqlite3_column_text()], etc. into
-** [sqlite3_free()].
-**
-** As long as the input parameters are correct, these routines will only
-** fail if an out-of-memory error occurs during a format conversion.
-** Only the following subset of interfaces are subject to out-of-memory
-** errors:
-**
-**
-** - sqlite3_column_blob()
-**
- sqlite3_column_text()
-**
- sqlite3_column_text16()
-**
- sqlite3_column_bytes()
-**
- sqlite3_column_bytes16()
-**
-**
-** If an out-of-memory error occurs, then the return value from these
-** routines is the same as if the column had contained an SQL NULL value.
-** Valid SQL NULL returns can be distinguished from out-of-memory errors
-** by invoking the [sqlite3_errcode()] immediately after the suspect
-** return value is obtained and before any
-** other SQLite interface is called on the same [database connection].

-** CAPI3REF: Create Or Redefine SQL Functions
-** KEYWORDS: {function creation routines}
-** METHOD: sqlite3
-**
-** ^These functions (collectively known as "function creation routines")
-** are used to add SQL functions or aggregates or to redefine the behavior
-** of existing SQL functions or aggregates. The only differences between
-** the three "sqlite3_create_function*" routines are the text encoding
-** expected for the second parameter (the name of the function being
-** created) and the presence or absence of a destructor callback for
-** the application data pointer. Function sqlite3_create_window_function()
-** is similar, but allows the user to supply the extra callback functions
-** needed by [aggregate window functions].
-**
-** ^The first parameter is the [database connection] to which the SQL
-** function is to be added. ^If an application uses more than one database
-** connection then application-defined SQL functions must be added
-** to each database connection separately.
-**
-** ^The second parameter is the name of the SQL function to be created or
-** redefined. ^The length of the name is limited to 255 bytes in a UTF-8
-** representation, exclusive of the zero-terminator. ^Note that the name
-** length limit is in UTF-8 bytes, not characters nor UTF-16 bytes.
-** ^Any attempt to create a function with a longer name
-** will result in [SQLITE_MISUSE] being returned.
-**
-** ^The third parameter (nArg)
-** is the number of arguments that the SQL function or
-** aggregate takes. ^If this parameter is -1, then the SQL function or
-** aggregate may take any number of arguments between 0 and the limit
-** set by [sqlite3_limit]([SQLITE_LIMIT_FUNCTION_ARG]). If the third
-** parameter is less than -1 or greater than 127 then the behavior is
-** undefined.
-**
-** ^The fourth parameter, eTextRep, specifies what
-** [SQLITE_UTF8 | text encoding] this SQL function prefers for
-** its parameters. The application should set this parameter to
-** [SQLITE_UTF16LE] if the function implementation invokes
-** [sqlite3_value_text16le()] on an input, or [SQLITE_UTF16BE] if the
-** implementation invokes [sqlite3_value_text16be()] on an input, or
-** [SQLITE_UTF16] if [sqlite3_value_text16()] is used, or [SQLITE_UTF8]
-** otherwise. ^The same SQL function may be registered multiple times using
-** different preferred text encodings, with different implementations for
-** each encoding.
-** ^When multiple implementations of the same function are available, SQLite
-** will pick the one that involves the least amount of data conversion.
-**
-** ^The fourth parameter may optionally be ORed with [SQLITE_DETERMINISTIC]
-** to signal that the function will always return the same result given
-** the same inputs within a single SQL statement. Most SQL functions are
-** deterministic. The built-in [random()] SQL function is an example of a
-** function that is not deterministic. The SQLite query planner is able to
-** perform additional optimizations on deterministic functions, so use
-** of the [SQLITE_DETERMINISTIC] flag is recommended where possible.
-**
-** ^The fourth parameter may also optionally include the [SQLITE_DIRECTONLY]
-** flag, which if present prevents the function from being invoked from
-** within VIEWs, TRIGGERs, CHECK constraints, generated column expressions,
-** index expressions, or the WHERE clause of partial indexes.
-**
-**
-** For best security, the [SQLITE_DIRECTONLY] flag is recommended for
-** all application-defined SQL functions that do not need to be
-** used inside of triggers, view, CHECK constraints, or other elements of
-** the database schema. This flags is especially recommended for SQL
-** functions that have side effects or reveal internal application state.
-** Without this flag, an attacker might be able to modify the schema of
-** a database file to include invocations of the function with parameters
-** chosen by the attacker, which the application will then execute when
-** the database file is opened and read.
-**
-**
-** ^(The fifth parameter is an arbitrary pointer. The implementation of the
-** function can gain access to this pointer using [sqlite3_user_data()].)^
-**
-** ^The sixth, seventh and eighth parameters passed to the three
-** "sqlite3_create_function*" functions, xFunc, xStep and xFinal, are
-** pointers to C-language functions that implement the SQL function or
-** aggregate. ^A scalar SQL function requires an implementation of the xFunc
-** callback only; NULL pointers must be passed as the xStep and xFinal
-** parameters. ^An aggregate SQL function requires an implementation of xStep
-** and xFinal and NULL pointer must be passed for xFunc. ^To delete an existing
-** SQL function or aggregate, pass NULL pointers for all three function
-** callbacks.
-**
-** ^The sixth, seventh, eighth and ninth parameters (xStep, xFinal, xValue
-** and xInverse) passed to sqlite3_create_window_function are pointers to
-** C-language callbacks that implement the new function. xStep and xFinal
-** must both be non-NULL. xValue and xInverse may either both be NULL, in
-** which case a regular aggregate function is created, or must both be
-** non-NULL, in which case the new function may be used as either an aggregate
-** or aggregate window function. More details regarding the implementation
-** of aggregate window functions are
-** [user-defined window functions|available here].
-**
-** ^(If the final parameter to sqlite3_create_function_v2() or
-** sqlite3_create_window_function() is not NULL, then it is destructor for
-** the application data pointer. The destructor is invoked when the function
-** is deleted, either by being overloaded or when the database connection
-** closes.)^ ^The destructor is also invoked if the call to
-** sqlite3_create_function_v2() fails. ^When the destructor callback is
-** invoked, it is passed a single argument which is a copy of the application
-** data pointer which was the fifth parameter to sqlite3_create_function_v2().
-**
-** ^It is permitted to register multiple implementations of the same
-** functions with the same name but with either differing numbers of
-** arguments or differing preferred text encodings. ^SQLite will use
-** the implementation that most closely matches the way in which the
-** SQL function is used. ^A function implementation with a non-negative
-** nArg parameter is a better match than a function implementation with
-** a negative nArg. ^A function where the preferred text encoding
-** matches the database encoding is a better
-** match than a function where the encoding is different.
-** ^A function where the encoding difference is between UTF16le and UTF16be
-** is a closer match than a function where the encoding difference is
-** between UTF8 and UTF16.
-**
-** ^Built-in functions may be overloaded by new application-defined functions.
-**
-** ^An application-defined function is permitted to call other
-** SQLite interfaces. However, such calls must not
-** close the database connection nor finalize or reset the prepared
-** statement in which the function is running.

-** [sqlite3_create_function_v2()].
-**
-**
-** [[SQLITE_DETERMINISTIC]] - SQLITE_DETERMINISTIC
-
-** The SQLITE_DETERMINISTIC flag means that the new function always gives
-** the same output when the input parameters are the same.
-** The [abs|abs() function] is deterministic, for example, but
-** [randomblob|randomblob()] is not. Functions must
-** be deterministic in order to be used in certain contexts such as
-** with the WHERE clause of [partial indexes] or in [generated columns].
-** SQLite might also optimize deterministic functions by factoring them
-** out of inner loops.
-**
-**
-** [[SQLITE_DIRECTONLY]] - SQLITE_DIRECTONLY
-
-** The SQLITE_DIRECTONLY flag means that the function may only be invoked
-** from top-level SQL, and cannot be used in VIEWs or TRIGGERs nor in
-** schema structures such as [CHECK constraints], [DEFAULT clauses],
-** [expression indexes], [partial indexes], or [generated columns].
-** The SQLITE_DIRECTONLY flags is a security feature which is recommended
-** for all [application-defined SQL functions], and especially for functions
-** that have side-effects or that could potentially leak sensitive
-** information.
-**
-**
-** [[SQLITE_INNOCUOUS]] - SQLITE_INNOCUOUS
-
-** The SQLITE_INNOCUOUS flag means that the function is unlikely
-** to cause problems even if misused. An innocuous function should have
-** no side effects and should not depend on any values other than its
-** input parameters. The [abs|abs() function] is an example of an
-** innocuous function.
-** The [load_extension() SQL function] is not innocuous because of its
-** side effects.
-**
SQLITE_INNOCUOUS is similar to SQLITE_DETERMINISTIC, but is not
-** exactly the same. The [random|random() function] is an example of a
-** function that is innocuous but not deterministic.
-** Some heightened security settings
-** ([SQLITE_DBCONFIG_TRUSTED_SCHEMA] and [PRAGMA trusted_schema=OFF])
-** disable the use of SQL functions inside views and triggers and in
-** schema structures such as [CHECK constraints], [DEFAULT clauses],
-** [expression indexes], [partial indexes], and [generated columns] unless
-** the function is tagged with SQLITE_INNOCUOUS. Most built-in functions
-** are innocuous. Developers are advised to avoid using the
-** SQLITE_INNOCUOUS flag for application-defined functions unless the

-** security-adverse side-effects and information-leaks.
-**
-**
-** [[SQLITE_SUBTYPE]] - SQLITE_SUBTYPE
-
-** The SQLITE_SUBTYPE flag indicates to SQLite that a function may call
-** [sqlite3_value_subtype()] to inspect the sub-types of its arguments.
-** Specifying this flag makes no difference for scalar or aggregate user
-** functions. However, if it is not specified for a user-defined window
-** function, then any sub-types belonging to arguments passed to the window
-** function may be discarded before the window function is called (i.e.
-** sqlite3_value_subtype() will always return 0).

-** | | sqlite3_value_frombind
-** | → | True if value originated from a [bound parameter]
-** |
-**
-** Details:
-**
-** These routines extract type, size, and content information from
-** [protected sqlite3_value] objects. Protected sqlite3_value objects
-** are used to pass parameter information into the functions that
-** implement [application-defined SQL functions] and [virtual tables].
-**
-** These routines work only with [protected sqlite3_value] objects.
-** Any attempt to use these routines on an [unprotected sqlite3_value]
-** is not threadsafe.
-**
-** ^These routines work just like the corresponding [column access functions]
-** except that these routines take a single [protected sqlite3_value] object
-** pointer instead of a [sqlite3_stmt*] pointer and an integer column number.
-**
-** ^The sqlite3_value_text16() interface extracts a UTF-16 string
-** in the native byte-order of the host machine. ^The
-** sqlite3_value_text16be() and sqlite3_value_text16le() interfaces
-** extract UTF-16 strings as big-endian and little-endian respectively.
-**
-** ^If [sqlite3_value] object V was initialized
-** using [sqlite3_bind_pointer(S,I,P,X,D)] or [sqlite3_result_pointer(C,P,X,D)]
-** and if X and Y are strings that compare equal according to strcmp(X,Y),
-** then sqlite3_value_pointer(V,Y) will return the pointer P. ^Otherwise,
-** sqlite3_value_pointer(V,Y) returns a NULL. The sqlite3_bind_pointer()
-** routine is part of the [pointer passing interface] added for SQLite 3.20.0.
-**
-** ^(The sqlite3_value_type(V) interface returns the
-** [SQLITE_INTEGER | datatype code] for the initial datatype of the
-** [sqlite3_value] object V. The returned value is one of [SQLITE_INTEGER],
-** [SQLITE_FLOAT], [SQLITE_TEXT], [SQLITE_BLOB], or [SQLITE_NULL].)^
-** Other interfaces might change the datatype for an sqlite3_value object.
-** For example, if the datatype is initially SQLITE_INTEGER and
-** sqlite3_value_text(V) is called to extract a text value for that
-** integer, then subsequent calls to sqlite3_value_type(V) might return
-** SQLITE_TEXT. Whether or not a persistent internal datatype conversion
-** occurs is undefined and may change from one release of SQLite to the next.
-**
-** ^(The sqlite3_value_numeric_type() interface attempts to apply
-** numeric affinity to the value. This means that an attempt is
-** made to convert the value to an integer or floating point. If
-** such a conversion is possible without loss of information (in other
-** words, if the value is a string that looks like a number)
-** then the conversion is performed. Otherwise no conversion occurs.
-** The [SQLITE_INTEGER | datatype] after conversion is returned.)^
-**
-** ^Within the [xUpdate] method of a [virtual table], the
-** sqlite3_value_nochange(X) interface returns true if and only if
-** the column corresponding to X is unchanged by the UPDATE operation
-** that the xUpdate method call was invoked to implement and if
-** and the prior [xColumn] method call that was invoked to extracted
-** the value for that column returned without setting a result (probably
-** because it queried [sqlite3_vtab_nochange()] and found that the column
-** was unchanging). ^Within an [xUpdate] method, any value for which
-** sqlite3_value_nochange(X) is true will in all other respects appear
-** to be a NULL value. If sqlite3_value_nochange(X) is invoked anywhere other
-** than within an [xUpdate] method call for an UPDATE statement, then
-** the return value is arbitrary and meaningless.
-**
-** ^The sqlite3_value_frombind(X) interface returns non-zero if the
-** value X originated from one of the [sqlite3_bind_int|sqlite3_bind()]
-** interfaces. ^If X comes from an SQL literal value, or a table column,
-** or an expression, then sqlite3_value_frombind(X) returns zero.
-**
-** Please pay particular attention to the fact that the pointer returned
-** from [sqlite3_value_blob()], [sqlite3_value_text()], or
-** [sqlite3_value_text16()] can be invalidated by a subsequent call to
-** [sqlite3_value_bytes()], [sqlite3_value_bytes16()], [sqlite3_value_text()],
-** or [sqlite3_value_text16()].
-**
-** These routines must be called from the same thread as
-** the SQL function that supplied the [sqlite3_value*] parameters.
-**
-** As long as the input parameter is correct, these routines can only
-** fail if an out-of-memory error occurs during a format conversion.
-** Only the following subset of interfaces are subject to out-of-memory
-** errors:
-**
-**
-** - sqlite3_value_blob()
-**
- sqlite3_value_text()
-**
- sqlite3_value_text16()
-**
- sqlite3_value_text16le()
-**
- sqlite3_value_text16be()
-**
- sqlite3_value_bytes()
-**
- sqlite3_value_bytes16()
-**
-**
-** If an out-of-memory error occurs, then the return value from these
-** routines is the same as if the column had contained an SQL NULL value.
-** Valid SQL NULL returns can be distinguished from out-of-memory errors
-** by invoking the [sqlite3_errcode()] immediately after the suspect
-** return value is obtained and before any
-** other SQLite interface is called on the same [database connection].

-** for additional information.
-**
-** These functions work very much like the [parameter binding] family of
-** functions used to bind values to host parameters in prepared statements.
-** Refer to the [SQL parameter] documentation for additional information.
-**
-** ^The sqlite3_result_blob() interface sets the result from
-** an application-defined function to be the BLOB whose content is pointed
-** to by the second parameter and which is N bytes long where N is the
-** third parameter.
-**
-** ^The sqlite3_result_zeroblob(C,N) and sqlite3_result_zeroblob64(C,N)
-** interfaces set the result of the application-defined function to be
-** a BLOB containing all zero bytes and N bytes in size.
-**
-** ^The sqlite3_result_double() interface sets the result from
-** an application-defined function to be a floating point value specified
-** by its 2nd argument.
-**
-** ^The sqlite3_result_error() and sqlite3_result_error16() functions
-** cause the implemented SQL function to throw an exception.
-** ^SQLite uses the string pointed to by the
-** 2nd parameter of sqlite3_result_error() or sqlite3_result_error16()
-** as the text of an error message. ^SQLite interprets the error
-** message string from sqlite3_result_error() as UTF-8. ^SQLite
-** interprets the string from sqlite3_result_error16() as UTF-16 using
-** the same [byte-order determination rules] as [sqlite3_bind_text16()].
-** ^If the third parameter to sqlite3_result_error()
-** or sqlite3_result_error16() is negative then SQLite takes as the error
-** message all text up through the first zero character.
-** ^If the third parameter to sqlite3_result_error() or
-** sqlite3_result_error16() is non-negative then SQLite takes that many
-** bytes (not characters) from the 2nd parameter as the error message.
-** ^The sqlite3_result_error() and sqlite3_result_error16()
-** routines make a private copy of the error message text before
-** they return. Hence, the calling function can deallocate or
-** modify the text after they return without harm.
-** ^The sqlite3_result_error_code() function changes the error code
-** returned by SQLite as a result of an error in a function. ^By default,
-** the error code is SQLITE_ERROR. ^A subsequent call to sqlite3_result_error()
-** or sqlite3_result_error16() resets the error code to SQLITE_ERROR.
-**
-** ^The sqlite3_result_error_toobig() interface causes SQLite to throw an
-** error indicating that a string or BLOB is too long to represent.
-**
-** ^The sqlite3_result_error_nomem() interface causes SQLite to throw an
-** error indicating that a memory allocation failed.
-**
-** ^The sqlite3_result_int() interface sets the return value
-** of the application-defined function to be the 32-bit signed integer
-** value given in the 2nd argument.
-** ^The sqlite3_result_int64() interface sets the return value
-** of the application-defined function to be the 64-bit signed integer
-** value given in the 2nd argument.
-**
-** ^The sqlite3_result_null() interface sets the return value
-** of the application-defined function to be NULL.
-**
-** ^The sqlite3_result_text(), sqlite3_result_text16(),
-** sqlite3_result_text16le(), and sqlite3_result_text16be() interfaces
-** set the return value of the application-defined function to be
-** a text string which is represented as UTF-8, UTF-16 native byte order,
-** UTF-16 little endian, or UTF-16 big endian, respectively.
-** ^The sqlite3_result_text64() interface sets the return value of an
-** application-defined function to be a text string in an encoding
-** specified by the fifth (and last) parameter, which must be one
-** of [SQLITE_UTF8], [SQLITE_UTF16], [SQLITE_UTF16BE], or [SQLITE_UTF16LE].
-** ^SQLite takes the text result from the application from
-** the 2nd parameter of the sqlite3_result_text* interfaces.
-** ^If the 3rd parameter to the sqlite3_result_text* interfaces
-** is negative, then SQLite takes result text from the 2nd parameter
-** through the first zero character.
-** ^If the 3rd parameter to the sqlite3_result_text* interfaces
-** is non-negative, then as many bytes (not characters) of the text
-** pointed to by the 2nd parameter are taken as the application-defined
-** function result. If the 3rd parameter is non-negative, then it
-** must be the byte offset into the string where the NUL terminator would
-** appear if the string where NUL terminated. If any NUL characters occur
-** in the string at a byte offset that is less than the value of the 3rd
-** parameter, then the resulting string will contain embedded NULs and the
-** result of expressions operating on strings with embedded NULs is undefined.
-** ^If the 4th parameter to the sqlite3_result_text* interfaces
-** or sqlite3_result_blob is a non-NULL pointer, then SQLite calls that
-** function as the destructor on the text or BLOB result when it has
-** finished using that result.
-** ^If the 4th parameter to the sqlite3_result_text* interfaces or to
-** sqlite3_result_blob is the special constant SQLITE_STATIC, then SQLite
-** assumes that the text or BLOB result is in constant space and does not
-** copy the content of the parameter nor call a destructor on the content
-** when it has finished using that result.
-** ^If the 4th parameter to the sqlite3_result_text* interfaces
-** or sqlite3_result_blob is the special constant SQLITE_TRANSIENT
-** then SQLite makes a copy of the result into space obtained
-** from [sqlite3_malloc()] before it returns.
-**
-** ^For the sqlite3_result_text16(), sqlite3_result_text16le(), and
-** sqlite3_result_text16be() routines, and for sqlite3_result_text64()
-** when the encoding is not UTF8, if the input UTF16 begins with a
-** byte-order mark (BOM, U+FEFF) then the BOM is removed from the
-** string and the rest of the string is interpreted according to the
-** byte-order specified by the BOM. ^The byte-order specified by
-** the BOM at the beginning of the text overrides the byte-order
-** specified by the interface procedure. ^So, for example, if
-** sqlite3_result_text16le() is invoked with text that begins
-** with bytes 0xfe, 0xff (a big-endian byte-order mark) then the
-** first two bytes of input are skipped and the remaining input
-** is interpreted as UTF16BE text.
-**
-** ^For UTF16 input text to the sqlite3_result_text16(),
-** sqlite3_result_text16be(), sqlite3_result_text16le(), and
-** sqlite3_result_text64() routines, if the text contains invalid
-** UTF16 characters, the invalid characters might be converted
-** into the unicode replacement character, U+FFFD.
-**
-** ^The sqlite3_result_value() interface sets the result of
-** the application-defined function to be a copy of the
-** [unprotected sqlite3_value] object specified by the 2nd parameter. ^The
-** sqlite3_result_value() interface makes a copy of the [sqlite3_value]
-** so that the [sqlite3_value] specified in the parameter may change or
-** be deallocated after sqlite3_result_value() returns without harm.
-** ^A [protected sqlite3_value] object may always be used where an
-** [unprotected sqlite3_value] object is required, so either
-** kind of [sqlite3_value] object can be used with this interface.
-**
-** ^The sqlite3_result_pointer(C,P,T,D) interface sets the result to an
-** SQL NULL value, just like [sqlite3_result_null(C)], except that it
-** also associates the host-language pointer P or type T with that
-** NULL value such that the pointer can be retrieved within an
-** [application-defined SQL function] using [sqlite3_value_pointer()].
-** ^If the D parameter is not NULL, then it is a pointer to a destructor
-** for the P parameter. ^SQLite invokes D with P as its only argument
-** when SQLite is finished with P. The T parameter should be a static

- [SQLITE_UTF16BE],
-**
- [SQLITE_UTF16], or

-** ^The eTextRep argument determines the encoding of strings passed
-** to the collating function callback, xCompare.
-** ^The [SQLITE_UTF16] and [SQLITE_UTF16_ALIGNED] values for eTextRep
-** force strings to be UTF16 with native byte order.
-** ^The [SQLITE_UTF16_ALIGNED] value for eTextRep forces strings to begin
-** on an even byte address.
-**
-** ^The fourth argument, pArg, is an application data pointer that is passed
-** through as the first argument to the collating function callback.
-**
-** ^The fifth argument, xCompare, is a pointer to the collating function.
-** ^Multiple collating functions can be registered using the same name but
-** with different eTextRep parameters and SQLite will use whichever
-** function requires the least amount of data transformation.
-** ^If the xCompare argument is NULL then the collating function is
-** deleted. ^When all collating functions having the same name are deleted,
-** that collation is no longer usable.
-**
-** ^The collating function callback is invoked with a copy of the pArg
-** application data pointer and with two strings in the encoding specified
-** by the eTextRep argument. The two integer parameters to the collating
-** function callback are the length of the two strings, in bytes. The collating
-** function must return an integer that is negative, zero, or positive
-** if the first string is less than, equal to, or greater than the second,
-** respectively. A collating function must always return the same answer
-** given the same inputs. If two or more collating functions are registered
-** to the same collation name (using different eTextRep values) then all
-** must give an equivalent answer when invoked with equivalent strings.
-** The collating function must obey the following properties for all

-** CAPI3REF: Virtual Table Indexing Information
-** KEYWORDS: sqlite3_index_info
-**
-** The sqlite3_index_info structure and its substructures is used as part
-** of the [virtual table] interface to
-** pass information into and receive the reply from the [xBestIndex]
-** method of a [virtual table module]. The fields under **Inputs** are the
-** inputs to xBestIndex and are read-only. xBestIndex inserts its
-** results into the **Outputs** fields.
-**
-** ^(The aConstraint[] array records WHERE clause constraints of the form:
-**
-** column OP expr
-**
-** where OP is =, <, <=, >, or >=.)^ ^(The particular operator is
-** stored in aConstraint[].op using one of the
-** [SQLITE_INDEX_CONSTRAINT_EQ | SQLITE_INDEX_CONSTRAINT_ values].)^
-** ^(The index of the column is stored in
-** aConstraint[].iColumn.)^ ^(aConstraint[].usable is TRUE if the
-** expr on the right-hand side can be evaluated (and thus the constraint
-** is usable) and false if it cannot.)^
-**
-** ^The optimizer automatically inverts terms of the form "expr OP column"
-** and makes other simplifications to the WHERE clause in an attempt to
-** get as many WHERE clause terms into the form shown above as possible.
-** ^The aConstraint[] array only reports WHERE clause terms that are
-** relevant to the particular virtual table being queried.
-**
-** ^Information about the ORDER BY clause is stored in aOrderBy[].
-** ^Each term of aOrderBy records a column of the ORDER BY clause.
-**
-** The colUsed field indicates which columns of the virtual table may be
-** required by the current scan. Virtual table columns are numbered from
-** zero in the order in which they appear within the CREATE TABLE statement
-** passed to sqlite3_declare_vtab(). For the first 63 columns (columns 0-62),
-** the corresponding bit is set within the colUsed mask if the column may be
-** required by SQLite. If the table has at least 64 columns and any column
-** to the right of the first 63 is required, then bit 63 of colUsed is also
-** set. In other words, column iCol may be required if the expression
-** (colUsed & ((sqlite3_uint64)1 << (iCol>=63 ? 63 : iCol))) evaluates to
-** non-zero.
-**
-** The [xBestIndex] method must fill aConstraintUsage[] with information
-** about what parameters to pass to xFilter. ^If argvIndex>0 then
-** the right-hand side of the corresponding aConstraint[] is evaluated
-** and becomes the argvIndex-th entry in argv. ^(If aConstraintUsage[].omit
-** is true, then the constraint is assumed to be fully handled by the
-** virtual table and might not be checked again by the byte code.)^ ^(The
-** aConstraintUsage[].omit flag is an optimization hint. When the omit flag
-** is left in its default setting of false, the constraint will always be
-** checked separately in byte code. If the omit flag is change to true, then
-** the constraint may or may not be checked in byte code. In other words,
-** when the omit flag is true there is no guarantee that the constraint will
-** not be checked again using byte code.)^
-**
-** ^The idxNum and idxPtr values are recorded and passed into the
-** [xFilter] method.
-** ^[sqlite3_free()] is used to free idxPtr if and only if
-** needToFreeIdxPtr is true.
-**
-** ^The orderByConsumed means that output from [xFilter]/[xNext] will occur in
-** the correct order to satisfy the ORDER BY clause so that no separate
-** sorting step is required.
-**
-** ^The estimatedCost value is an estimate of the cost of a particular
-** strategy. A cost of N indicates that the cost of the strategy is similar
-** to a linear scan of an SQLite table with N rows. A cost of log(N)
-** indicates that the expense of the operation is similar to that of a
-** binary search on a unique indexed field of an SQLite table with N rows.
-**
-** ^The estimatedRows value is an estimate of the number of rows that
-** will be returned by the strategy.
-**
-** The xBestIndex method may optionally populate the idxFlags field with a
-** mask of SQLITE_INDEX_SCAN_* flags. Currently there is only one such flag -
-** SQLITE_INDEX_SCAN_UNIQUE. If the xBestIndex method sets this flag, SQLite
-** assumes that the strategy may visit at most one row.
-**
-** Additionally, if xBestIndex sets the SQLITE_INDEX_SCAN_UNIQUE flag, then
-** SQLite also assumes that if a call to the xUpdate() method is made as
-** part of the same statement to delete or update a virtual table row and the
-** implementation returns SQLITE_CONSTRAINT, then there is no need to rollback
-** any database changes. In other words, if the xUpdate() returns
-** SQLITE_CONSTRAINT, the database contents must be exactly as they were
-** before xUpdate was called. By contrast, if SQLITE_INDEX_SCAN_UNIQUE is not
-** set and xUpdate returns SQLITE_CONSTRAINT, any database changes made by
-** the xUpdate method are automatically rolled back by SQLite.
-**
-** IMPORTANT: The estimatedRows field was added to the sqlite3_index_info
-** structure for SQLite [version 3.8.2] ([dateof:3.8.2]).
-** If a virtual table extension is
-** used with an SQLite version earlier than 3.8.2, the results of attempting
-** to read or write the estimatedRows field are undefined (but are likely
-** to include crashing the application). The estimatedRows field should
-** therefore only be used if [sqlite3_libversion_number()] returns a
-** value greater than or equal to 3008002. Similarly, the idxFlags field
-** was added for [version 3.9.0] ([dateof:3.9.0]).
-** It may therefore only be used if
-** sqlite3_libversion_number() returns a value greater than or equal to

-** CAPI3REF: Mutexes
-**
-** The SQLite core uses these routines for thread
-** synchronization. Though they are intended for internal
-** use by SQLite, code that links against SQLite is
-** permitted to use any of these routines.
-**
-** The SQLite source code contains multiple implementations
-** of these mutex routines. An appropriate implementation
-** is selected automatically at compile-time. The following
-** implementations are available in the SQLite core:
-**
-**
-** - SQLITE_MUTEX_PTHREADS
-**
- SQLITE_MUTEX_W32
-**
- SQLITE_MUTEX_NOOP
-**
-**
-** The SQLITE_MUTEX_NOOP implementation is a set of routines
-** that does no real locking and is appropriate for use in
-** a single-threaded application. The SQLITE_MUTEX_PTHREADS and
-** SQLITE_MUTEX_W32 implementations are appropriate for use on Unix
-** and Windows.
-**
-** If SQLite is compiled with the SQLITE_MUTEX_APPDEF preprocessor
-** macro defined (with "-DSQLITE_MUTEX_APPDEF=1"), then no mutex
-** implementation is included with the library. In this case the
-** application must supply a custom mutex implementation using the
-** [SQLITE_CONFIG_MUTEX] option of the sqlite3_config() function
-** before calling sqlite3_initialize() or any other public sqlite3_
-** function that calls sqlite3_initialize().
-**
-** ^The sqlite3_mutex_alloc() routine allocates a new
-** mutex and returns a pointer to it. ^The sqlite3_mutex_alloc()
-** routine returns NULL if it is unable to allocate the requested
-** mutex. The argument to sqlite3_mutex_alloc() must one of these
-** integer constants:
-**
-**
-** - SQLITE_MUTEX_FAST
-**
- SQLITE_MUTEX_RECURSIVE
-**
- SQLITE_MUTEX_STATIC_MAIN
-**
- SQLITE_MUTEX_STATIC_MEM

- SQLITE_MUTEX_STATIC_VFS2
-**
- SQLITE_MUTEX_STATIC_VFS3
-**
-**
-** ^The first two constants (SQLITE_MUTEX_FAST and SQLITE_MUTEX_RECURSIVE)
-** cause sqlite3_mutex_alloc() to create
-** a new mutex. ^The new mutex is recursive when SQLITE_MUTEX_RECURSIVE
-** is used but not necessarily so when SQLITE_MUTEX_FAST is used.
-** The mutex implementation does not need to make a distinction
-** between SQLITE_MUTEX_RECURSIVE and SQLITE_MUTEX_FAST if it does
-** not want to. SQLite will only request a recursive mutex in
-** cases where it really needs one. If a faster non-recursive mutex
-** implementation is available on the host platform, the mutex subsystem
-** might return such a mutex in response to SQLITE_MUTEX_FAST.
-**
-** ^The other allowed parameters to sqlite3_mutex_alloc() (anything other
-** than SQLITE_MUTEX_FAST and SQLITE_MUTEX_RECURSIVE) each return
-** a pointer to a static preexisting mutex. ^Nine static mutexes are
-** used by the current version of SQLite. Future versions of SQLite
-** may add additional static mutexes. Static mutexes are for internal
-** use by SQLite only. Applications that use SQLite mutexes should
-** use only the dynamic mutexes returned by SQLITE_MUTEX_FAST or
-** SQLITE_MUTEX_RECURSIVE.
-**
-** ^Note that if one of the dynamic mutex parameters (SQLITE_MUTEX_FAST
-** or SQLITE_MUTEX_RECURSIVE) is used then sqlite3_mutex_alloc()
-** returns a different mutex on every call. ^For the static
-** mutex types, the same mutex is returned on every call that has
-** the same type number.
-**
-** ^The sqlite3_mutex_free() routine deallocates a previously
-** allocated dynamic mutex. Attempting to deallocate a static
-** mutex results in undefined behavior.
-**
-** ^The sqlite3_mutex_enter() and sqlite3_mutex_try() routines attempt
-** to enter a mutex. ^If another thread is already within the mutex,
-** sqlite3_mutex_enter() will block and sqlite3_mutex_try() will return
-** SQLITE_BUSY. ^The sqlite3_mutex_try() interface returns [SQLITE_OK]
-** upon successful entry. ^(Mutexes created using
-** SQLITE_MUTEX_RECURSIVE can be entered multiple times by the same thread.
-** In such cases, the
-** mutex must be exited an equal number of times before another thread
-** can enter.)^ If the same thread tries to enter any mutex other
-** than an SQLITE_MUTEX_RECURSIVE more than once, the behavior is undefined.

-** sufficient, however the application has the option of substituting a custom
-** implementation for specialized deployments or systems for which SQLite
-** does not provide a suitable implementation. In this case, the application
-** creates and populates an instance of this structure to pass
-** to sqlite3_config() along with the [SQLITE_CONFIG_MUTEX] option.
-** Additionally, an instance of this structure can be used as an
-** output variable when querying the system for the current mutex
-** implementation, using the [SQLITE_CONFIG_GETMUTEX] option.
-**
-** ^The xMutexInit method defined by this structure is invoked as
-** part of system initialization by the sqlite3_initialize() function.
-** ^The xMutexInit routine is called by SQLite exactly once for each
-** effective call to [sqlite3_initialize()].
-**
-** ^The xMutexEnd method defined by this structure is invoked as
-** part of system shutdown by the sqlite3_shutdown() function. The
-** implementation of this method is expected to release all outstanding
-** resources obtained by the mutex methods implementation, especially
-** those obtained by the xMutexInit method. ^The xMutexEnd()
-** interface is invoked exactly once for each call to [sqlite3_shutdown()].
-**
-** ^(The remaining seven methods defined by this structure (xMutexAlloc,
-** xMutexFree, xMutexEnter, xMutexTry, xMutexLeave, xMutexHeld and
-** xMutexNotheld) implement the following interfaces (respectively):
-**
-**
-** - [sqlite3_mutex_alloc()]
-** - [sqlite3_mutex_free()]
-** - [sqlite3_mutex_enter()]
-** - [sqlite3_mutex_try()]
-** - [sqlite3_mutex_leave()]

-** of a valid mutex handle. The implementations of the methods defined
-** by this structure are not required to handle this case. The results
-** of passing a NULL pointer instead of a valid mutex handle are undefined
-** (i.e. it is acceptable to provide an implementation that segfaults if
-** it is passed a NULL pointer).
-**
-** The xMutexInit() method must be threadsafe. It must be harmless to
-** invoke xMutexInit() multiple times within the same process and without
-** intervening calls to xMutexEnd(). Second and subsequent calls to

-** CAPI3REF: SQL Keyword Checking
-**
-** These routines provide access to the set of SQL language keywords
-** recognized by SQLite. Applications can uses these routines to determine
-** whether or not a specific identifier needs to be escaped (for example,
-** by enclosing in double-quotes) so as not to confuse the parser.
-**
-** The sqlite3_keyword_count() interface returns the number of distinct
-** keywords understood by SQLite.
-**
-** The sqlite3_keyword_name(N,Z,L) interface finds the N-th keyword and
-** makes *Z point to that keyword expressed as UTF8 and writes the number
-** of bytes in the keyword into *L. The string that *Z points to is not
-** zero-terminated. The sqlite3_keyword_name(N,Z,L) routine returns
-** SQLITE_OK if N is within bounds and SQLITE_ERROR if not. If either Z
-** or L are NULL or invalid pointers then calls to
-** sqlite3_keyword_name(N,Z,L) result in undefined behavior.
-**
-** The sqlite3_keyword_check(Z,L) interface checks to see whether or not
-** the L-byte UTF8 identifier that Z points to is a keyword, returning non-zero
-** if it is and zero if not.
-**
-** The parser used by SQLite is forgiving. It is often possible to use
-** a keyword as an identifier as long as such use does not result in a
-** parsing ambiguity. For example, the statement
-** "CREATE TABLE BEGIN(REPLACE,PRAGMA,END);" is accepted by SQLite, and
-** creates a new table named "BEGIN" with three columns named
-** "REPLACE", "PRAGMA", and "END". Nevertheless, best practice is to avoid
-** using keywords as identifiers. Common techniques used to avoid keyword
-** name collisions include:
-**

-** page cache.)^
-**
-** [[the xShutdown() page cache method]]
-** ^The xShutdown() method is called by [sqlite3_shutdown()].
-** It can be used to clean up
-** any outstanding resources before process shutdown, if required.
-** ^The xShutdown() method may be NULL.
-**
-** ^SQLite automatically serializes calls to the xInit method,
-** so the xInit method need not be threadsafe. ^The
-** xShutdown method is only called from [sqlite3_shutdown()] so it does
-** not need to be threadsafe either. All other methods must be threadsafe
-** in multithreaded applications.
-**
-** ^SQLite will never invoke xInit() more than once without an intervening
-** call to xShutdown().
-**
-** [[the xCreate() page cache methods]]
-** ^SQLite invokes the xCreate() method to construct a new cache instance.
-** SQLite will typically create one cache instance for each open database file,
-** though this is not guaranteed. ^The
-** first parameter, szPage, is the size in bytes of the pages that must
-** be allocated by the cache. ^szPage will always a power of two. ^The
-** second parameter szExtra is a number of bytes of extra storage
-** associated with each page cache entry. ^The szExtra parameter will
-** a number less than 250. SQLite will use the
-** extra szExtra bytes on each page to store metadata about the underlying
-** database page on disk. The value passed into szExtra depends
-** on the SQLite version, the target platform, and how SQLite was compiled.
-** ^The third argument to xCreate(), bPurgeable, is true if the cache being
-** created will be used to cache database pages of a file stored on disk, or
-** false if it is used for an in-memory database. The cache implementation
-** does not have to do anything special based with the value of bPurgeable;
-** it is purely advisory. ^On a cache where bPurgeable is false, SQLite will
-** never invoke xUnpin() except to deliberately delete a page.
-** ^In other words, calls to xUnpin() on a cache with bPurgeable set to
-** false will always have the "discard" flag set to true.
-** ^Hence, a cache created with bPurgeable false will
-** never contain any unpinned pages.
-**
-** [[the xCachesize() page cache method]]
-** ^(The xCachesize() method may be called at any time by SQLite to set the
-** suggested maximum cache-size (number of pages stored by) the cache
-** instance passed as the first argument. This is the value configured using
-** the SQLite "[PRAGMA cache_size]" command.)^ As with the bPurgeable
-** parameter, the implementation is not required to do anything with this
-** value; it is advisory only.
-**
-** [[the xPagecount() page cache methods]]
-** The xPagecount() method must return the number of pages currently
-** stored in the cache, both pinned and unpinned.
-**
-** [[the xFetch() page cache methods]]
-** The xFetch() method locates a page in the cache and returns a pointer to
-** an sqlite3_pcache_page object associated with that page, or a NULL pointer.
-** The pBuf element of the returned sqlite3_pcache_page object will be a
-** pointer to a buffer of szPage bytes used to store the content of a
-** single database page. The pExtra element of sqlite3_pcache_page will be
-** a pointer to the szExtra bytes of extra storage that SQLite has requested
-** for each entry in the page cache.
-**
-** The page to be fetched is determined by the key. ^The minimum key value
-** is 1. After it has been retrieved using xFetch, the page is considered
-** to be "pinned".
-**
-** If the requested page is already in the page cache, then the page cache
-** implementation must return a pointer to the page buffer with its content
-** intact. If the requested page is not already in the cache, then the
-** cache implementation should use the value of the createFlag
-** parameter to help it determined what action to take:
-**
-**
-** | createFlag | Behavior when page is not already in cache
-** |
|---|
| 0 | Do not allocate a new page. Return NULL.
-** | | 1 | Allocate a new page if it easy and convenient to do so.
-** Otherwise return NULL.
-** | | 2 | Make every effort to allocate a new page. Only return
-** NULL if allocating a new page is effectively impossible.
-** |
-**
-** ^(SQLite will normally invoke xFetch() with a createFlag of 0 or 1. SQLite
-** will only use a createFlag of 2 after a prior call with a createFlag of 1
-** failed.)^ In between the xFetch() calls, SQLite may
-** attempt to unpin one or more cache pages by spilling the content of
-** pinned pages to disk and synching the operating system disk cache.
-**
-** [[the xUnpin() page cache method]]
-** ^xUnpin() is called by SQLite with a pointer to a currently pinned page
-** as its second argument. If the third parameter, discard, is non-zero,
-** then the page must be evicted from the cache.
-** ^If the discard parameter is
-** zero, then the page may be discarded or retained at the discretion of
-** page cache implementation. ^The page cache implementation
-** may choose to evict unpinned pages at any time.
-**
-** The cache must not perform any reference counting. A single
-** call to xUnpin() unpins the page regardless of the number of prior calls
-** to xFetch().
-**
-** [[the xRekey() page cache methods]]
-** The xRekey() method is used to change the key value associated with the
-** page passed as the second argument. If the cache
-** previously contains an entry associated with newKey, it must be
-** discarded. ^Any prior cache entry associated with newKey is guaranteed not
-** to be pinned.
-**
-** When SQLite calls the xTruncate() method, the cache must discard all
-** existing cache entries with page numbers (keys) greater than or equal
-** to the value of the iLimit parameter passed to xTruncate(). If any
-** of these pages are pinned, they are implicitly unpinned, meaning that
-** they can be safely discarded.
-**
-** [[the xDestroy() page cache method]]
-** ^The xDestroy() method is used to delete a cache allocated by xCreate().
-** All resources associated with the specified cache should be freed. ^After
-** calling the xDestroy() method, SQLite considers the [sqlite3_pcache*]
-** handle invalid, and will not use it with any other sqlite3_pcache_methods2
-** functions.
-**
-** [[the xShrink() page cache method]]
-** ^SQLite invokes the xShrink() method when it wants the page cache to
-** free up as much of heap memory as possible. The page cache implementation
-** is not obligated to free any memory, but well-behaved implementations should
-** do their best.

-** if the application incorrectly accesses the destination [database connection]
-** and so no error code is reported, but the operations may malfunction
-** nevertheless. Use of the destination database connection while a
-** backup is in progress might also also cause a mutex deadlock.
-**
-** If running in [shared cache mode], the application must
-** guarantee that the shared cache used by the destination database
-** is not accessed while the backup is running. In practice this means
-** that the application must guarantee that the disk file being
-** backed up to is not accessed by any connection within the process,
-** not just the specific connection that was passed to sqlite3_backup_init().
-**
-** The [sqlite3_backup] object itself is partially threadsafe. Multiple
-** threads may safely make multiple concurrent calls to sqlite3_backup_step().
-** However, the sqlite3_backup_remaining() and sqlite3_backup_pagecount()
-** APIs are not strictly speaking threadsafe. If they are invoked at the
-** same time as another thread is invoking sqlite3_backup_step() it is
-** possible that they return invalid values.

-** ^When running in shared-cache mode, a database operation may fail with

-** individual tables within the shared-cache cannot be obtained. See
-** [SQLite Shared-Cache Mode] for a description of shared-cache locking.
-** ^This API may be used to register a callback that SQLite will invoke
-** when the connection currently holding the required lock relinquishes it.
-** ^This API is only available if the library was compiled with the
-** [SQLITE_ENABLE_UNLOCK_NOTIFY] C-preprocessor symbol defined.
-**
-** See Also: [Using the SQLite Unlock Notification Feature].
-**
-** ^Shared-cache locks are released when a database connection concludes
-** its current transaction, either by committing it or rolling it back.
-**
-** ^When a connection (known as the blocked connection) fails to obtain a
-** shared-cache lock and SQLITE_LOCKED is returned to the caller, the
-** identity of the database connection (the blocking connection) that
-** has locked the required resource is stored internally. ^After an
-** application receives an SQLITE_LOCKED error, it may call the
-** sqlite3_unlock_notify() method with the blocked connection handle as
-** the first argument to register for a callback that will be invoked
-** when the blocking connections current transaction is concluded. ^The
-** callback is invoked from within the [sqlite3_step] or [sqlite3_close]
-** call that concludes the blocking connection's transaction.
-**
-** ^(If sqlite3_unlock_notify() is called in a multi-threaded application,
-** there is a chance that the blocking connection will have already
-** concluded its transaction by the time sqlite3_unlock_notify() is invoked.
-** If this happens, then the specified callback is invoked immediately,
-** from within the call to sqlite3_unlock_notify().)^
-**
-** ^If the blocked connection is attempting to obtain a write-lock on a
-** shared-cache table, and more than one other connection currently holds
-** a read-lock on the same table, then SQLite arbitrarily selects one of
-** the other connections to use as the blocking connection.
-**
-** ^(There may be at most one unlock-notify callback registered by a
-** blocked connection. If sqlite3_unlock_notify() is called when the
-** blocked connection already has a registered unlock-notify callback,
-** then the new callback replaces the old.)^ ^If sqlite3_unlock_notify() is
-** called with a NULL pointer as its second argument, then any existing
-** unlock-notify callback is canceled. ^The blocked connections
-** unlock-notify callback may also be canceled by closing the blocked
-** connection using [sqlite3_close()].
-**
-** The unlock-notify callback is not reentrant. If an application invokes
-** any sqlite3_xxx API functions from within an unlock-notify callback, a
-** crash or deadlock may be the result.
-**
-** ^Unless deadlock is detected (see below), sqlite3_unlock_notify() always
-** returns SQLITE_OK.
-**
-** Callback Invocation Details
-**
-** When an unlock-notify callback is registered, the application provides a
-** single void* pointer that is passed to the callback when it is invoked.
-** However, the signature of the callback function allows SQLite to pass
-** it an array of void* context pointers. The first argument passed to
-** an unlock-notify callback is a pointer to an array of void* pointers,
-** and the second is the number of entries in the array.
-**
-** When a blocking connection's transaction is concluded, there may be
-** more than one blocked connection that has registered for an unlock-notify
-** callback. ^If two or more such blocked connections have specified the
-** same callback function, then instead of invoking the callback function
-** multiple times, it is invoked once with the set of void* context pointers
-** specified by the blocked connections bundled together into an array.
-** This gives the application an opportunity to prioritize any actions
-** related to the set of unblocked database connections.
-**
-** Deadlock Detection
-**
-** Assuming that after registering for an unlock-notify callback a
-** database waits for the callback to be issued before taking any further
-** action (a reasonable assumption), then using this API may cause the
-** application to deadlock. For example, if connection X is waiting for
-** connection Y's transaction to be concluded, and similarly connection
-** Y is waiting on connection X's transaction, then neither connection
-** will proceed and the system may remain deadlocked indefinitely.
-**
-** To avoid this scenario, the sqlite3_unlock_notify() performs deadlock
-** detection. ^If a given call to sqlite3_unlock_notify() would put the
-** system in a deadlocked state, then SQLITE_LOCKED is returned and no
-** unlock-notify callback is registered. The system is said to be in
-** a deadlocked state if connection A has registered for an unlock-notify
-** callback on the conclusion of connection B's transaction, and connection
-** B has itself registered for an unlock-notify callback when connection
-** A's transaction is concluded. ^Indirect deadlock is also detected, so
-** the system is also considered to be deadlocked if connection B has
-** registered for an unlock-notify callback on the conclusion of connection
-** C's transaction, where connection C is waiting on connection A. ^Any
-** number of levels of indirection are allowed.
-**
-** The "DROP TABLE" Exception
-**
-** When a call to [sqlite3_step()] returns SQLITE_LOCKED, it is almost
-** always appropriate to call sqlite3_unlock_notify(). There is however,
-** one exception. When executing a "DROP TABLE" or "DROP INDEX" statement,
-** SQLite checks if there are any currently executing SELECT statements
-** that belong to the same connection. If there are, SQLITE_LOCKED is
-** returned. In this case there is no "blocking connection", so invoking
-** sqlite3_unlock_notify() results in the unlock-notify callback being
-** invoked immediately. If the application then re-attempts the "DROP TABLE"
-** or "DROP INDEX" query, an infinite loop might be the result.
-**
-** One way around this problem is to check the extended error code returned
-** by an sqlite3_step() call. ^(If there is a blocking connection, then the
-** extended error code is set to SQLITE_LOCKED_SHAREDCACHE. Otherwise, in
-** the special "DROP TABLE/INDEX" case, the extended error code is just
-** SQLITE_LOCKED.)^

-**
-** Changes can only be recorded for tables that have a PRIMARY KEY explicitly

-** PRIMARY KEY is an "INTEGER PRIMARY KEY" (rowid alias) or not. The PRIMARY
-** KEY may consist of a single column, or may be a composite key.
-**
-** It is not an error if the named table does not exist in the database. Nor
-** is it an error if the named table does not have a PRIMARY KEY. However,

-** Special sqlite_stat1 Handling
-**
-** As of SQLite version 3.22.0, the "sqlite_stat1" table is an exception to
-** some of the rules above. In SQLite, the schema of sqlite_stat1 is:
-**
-** CREATE TABLE sqlite_stat1(tbl,idx,stat)
-**
-**
-** Even though sqlite_stat1 does not have a PRIMARY KEY, changes are
-** recorded for it as if the PRIMARY KEY is (tbl,idx). Additionally, changes
-** are recorded for rows for which (idx IS NULL) is true. However, for such
-** rows a zero-length blob (SQL value X'') is stored in the changeset or
-** patchset instead of a NULL value. This allows such changesets to be
-** manipulated by legacy implementations of sqlite3changeset_invert(),
-** concat() and similar.
-**
-** The sqlite3changeset_apply() function automatically converts the
-** zero-length blob back to a NULL value when updating the sqlite_stat1
-** table. However, if the application calls sqlite3changeset_new(),
-** sqlite3changeset_old() or sqlite3changeset_conflict on a changeset
-** iterator directly (including on a changeset iterator passed to a
-** conflict-handler callback) then the X'' value is returned. The application
-** must translate X'' to NULL itself if required.
-**
-** Legacy (older than 3.22.0) versions of the sessions module cannot capture
-** changes made to the sqlite_stat1 table. Legacy versions of the
-** sqlite3changeset_apply() function silently ignore any modifications to the
-** sqlite_stat1 table that are part of a changeset or patchset.

-** and *pnChangeset to the size of the changeset in bytes before returning
-** SQLITE_OK. If an error occurs, set both *ppChangeset and *pnChangeset to
-** zero and return an SQLite error code.
-**
-** A changeset consists of zero or more INSERT, UPDATE and/or DELETE changes,
-** each representing a change to a single row of an attached table. An INSERT
-** change contains the values of each field of a new database row. A DELETE
-** contains the original values of each field of a deleted database row. An
-** UPDATE change contains the original values of each field of an updated
-** database row along with the updated values for each updated non-primary-key
-** column. It is not possible for an UPDATE change to represent a change that
-** modifies the values of primary key columns. If such a change is made, it
-** is represented in a changeset as a DELETE followed by an INSERT.
-**
-** Changes are not recorded for rows that have NULL values stored in one or
-** more of their PRIMARY KEY columns. If such a row is inserted or deleted,
-** no corresponding change is present in the changesets returned by this
-** function. If an existing row with one or more NULL values stored in
-** PRIMARY KEY columns is updated so that all PRIMARY KEY columns are non-NULL,
-** only an INSERT is appears in the changeset. Similarly, if an existing row
-** with non-NULL PRIMARY KEY values is updated so that one or more of its
-** PRIMARY KEY columns are set to NULL, the resulting changeset contains a
-** DELETE change only.
-**
-** The contents of a changeset may be traversed using an iterator created
-** using the [sqlite3changeset_start()] API. A changeset may be applied to
-** a database with a compatible schema using the [sqlite3changeset_apply()]
-** API.
-**
-** Within a changeset generated by this function, all changes related to a
-** single table are grouped together. In other words, when iterating through
-** a changeset or when applying a changeset to a database, all changes related
-** to a single table are processed before moving on to the next table. Tables
-** are sorted in the same order in which they were attached (or auto-attached)
-** to the sqlite3_session object. The order in which the changes related to
-** a single table are stored is undefined.
-**
-** Following a successful call to this function, it is the responsibility of
-** the caller to eventually free the buffer that *ppChangeset points to using
-** [sqlite3_free()].
-**
-** Changeset Generation
-**
-** Once a table has been attached to a session object, the session object
-** records the primary key values of all new rows inserted into the table.
-** It also records the original primary key and other column values of any
-** deleted or updated rows. For each unique primary key value, data is only
-** recorded once - the first time a row with said primary key is inserted,
-** updated or deleted in the lifetime of the session.
-**
-** There is one exception to the previous paragraph: when a row is inserted,
-** updated or deleted, if one or more of its primary key columns contain a
-** NULL value, no record of the change is made.
-**
-** The session object therefore accumulates two types of records - those
-** that consist of primary key values only (created when the user inserts
-** a new record) and those that consist of the primary key values and the
-** original values of other table columns (created when the users deletes
-** or updates a record).
-**
-** When this function is called, the requested changeset is created using
-** both the accumulated records and the current contents of the database
-** file. Specifically:
-**
-**
-** - For each record generated by an insert, the database is queried
-** for a row with a matching primary key. If one is found, an INSERT
-** change is added to the changeset. If no such row is found, no change
-** is added to the changeset.
-**
-**
- For each record generated by an update or delete, the database is
-** queried for a row with a matching primary key. If such a row is
-** found and one or more of the non-primary key fields have been
-** modified from their original values, an UPDATE change is added to
-** the changeset. Or, if no such row is found in the table, a DELETE
-** change is added to the changeset. If there is a row with a matching
-** primary key in the database, but all fields contain their original
-** values, no change is added to the changeset.
-**
-**
-** This means, amongst other things, that if a row is inserted and then later
-** deleted while a session object is active, neither the insert nor the delete
-** will be present in the changeset. Or if a row is deleted and then later a
-** row with the same primary key values inserted while a session object is
-** active, the resulting changeset will contain an UPDATE change instead of
-** a DELETE and an INSERT.
-**
-** When a session object is disabled (see the [sqlite3session_enable()] API),
-** it does not accumulate records when rows are inserted, updated or deleted.
-** This may appear to have some counter-intuitive effects if a single row
-** is written to more than once during a session. For example, if a row
-** is inserted while a session object is enabled, then later deleted while
-** the same session object is disabled, no INSERT record will appear in the
-** changeset, even though the delete took place while the session was disabled.
-** Or, if one field of a row is updated while a session is disabled, and
-** another field of the same row is updated while the session is enabled, the
-** resulting changeset will contain an UPDATE change that updates both fields.

-**
- For each row (primary key) that exists in the to-table but not in

-** CAPI3REF: Apply A Changeset To A Database
-**
-** Apply a changeset or patchset to a database. These functions attempt to
-** update the "main" database attached to handle db with the changes found in
-** the changeset passed via the second and third arguments.
-**
-** The fourth argument (xFilter) passed to these functions is the "filter
-** callback". If it is not NULL, then for each table affected by at least one
-** change in the changeset, the filter callback is invoked with
-** the table name as the second argument, and a copy of the context pointer
-** passed as the sixth argument as the first. If the "filter callback"
-** returns zero, then no attempt is made to apply any changes to the table.
-** Otherwise, if the return value is non-zero or the xFilter argument to
-** is NULL, all changes related to the table are attempted.
-**
-** For each table that is not excluded by the filter callback, this function
-** tests that the target database contains a compatible table. A table is
-** considered compatible if all of the following are true:
-**
-**
-** - The table has the same name as the name recorded in the
-** changeset, and
-**
- The table has at least as many columns as recorded in the
-** changeset, and
-**
- The table has primary key columns in the same position as
-** recorded in the changeset.
-**
-**
-** If there is no compatible table, it is not an error, but none of the
-** changes associated with the table are applied. A warning message is issued
-** via the sqlite3_log() mechanism with the error code SQLITE_SCHEMA. At most
-** one such warning is issued for each table in the changeset.
-**
-** For each change for which there is a compatible table, an attempt is made
-** to modify the table contents according to the UPDATE, INSERT or DELETE
-** change. If a change cannot be applied cleanly, the conflict handler
-** function passed as the fifth argument to sqlite3changeset_apply() may be
-** invoked. A description of exactly when the conflict handler is invoked for
-** each type of change is below.
-**
-** Unlike the xFilter argument, xConflict may not be passed NULL. The results
-** of passing anything other than a valid function pointer as the xConflict
-** argument are undefined.
-**
-** Each time the conflict handler function is invoked, it must return one
-** of [SQLITE_CHANGESET_OMIT], [SQLITE_CHANGESET_ABORT] or
-** [SQLITE_CHANGESET_REPLACE]. SQLITE_CHANGESET_REPLACE may only be returned
-** if the second argument passed to the conflict handler is either
-** SQLITE_CHANGESET_DATA or SQLITE_CHANGESET_CONFLICT. If the conflict-handler
-** returns an illegal value, any changes already made are rolled back and
-** the call to sqlite3changeset_apply() returns SQLITE_MISUSE. Different
-** actions are taken by sqlite3changeset_apply() depending on the value
-** returned by each invocation of the conflict-handler function. Refer to
-** the documentation for the three
-** [SQLITE_CHANGESET_OMIT|available return values] for details.
-**
-**
-** - DELETE Changes
-
-** For each DELETE change, the function checks if the target database
-** contains a row with the same primary key value (or values) as the
-** original row values stored in the changeset. If it does, and the values
-** stored in all non-primary key columns also match the values stored in
-** the changeset the row is deleted from the target database.
-**
-** If a row with matching primary key values is found, but one or more of
-** the non-primary key fields contains a value different from the original
-** row value stored in the changeset, the conflict-handler function is
-** invoked with [SQLITE_CHANGESET_DATA] as the second argument. If the
-** database table has more columns than are recorded in the changeset,
-** only the values of those non-primary key fields are compared against
-** the current database contents - any trailing database table columns
-** are ignored.
-**
-** If no row with matching primary key values is found in the database,
-** the conflict-handler function is invoked with [SQLITE_CHANGESET_NOTFOUND]
-** passed as the second argument.
-**
-** If the DELETE operation is attempted, but SQLite returns SQLITE_CONSTRAINT
-** (which can only happen if a foreign key constraint is violated), the
-** conflict-handler function is invoked with [SQLITE_CHANGESET_CONSTRAINT]
-** passed as the second argument. This includes the case where the DELETE
-** operation is attempted because an earlier call to the conflict handler
-** function returned [SQLITE_CHANGESET_REPLACE].
-**
-**
- INSERT Changes
-
-** For each INSERT change, an attempt is made to insert the new row into
-** the database. If the changeset row contains fewer fields than the
-** database table, the trailing fields are populated with their default
-** values.
-**
-** If the attempt to insert the row fails because the database already
-** contains a row with the same primary key values, the conflict handler
-** function is invoked with the second argument set to
-** [SQLITE_CHANGESET_CONFLICT].
-**
-** If the attempt to insert the row fails because of some other constraint
-** violation (e.g. NOT NULL or UNIQUE), the conflict handler function is
-** invoked with the second argument set to [SQLITE_CHANGESET_CONSTRAINT].
-** This includes the case where the INSERT operation is re-attempted because
-** an earlier call to the conflict handler function returned
-** [SQLITE_CHANGESET_REPLACE].
-**
-**
- UPDATE Changes
-
-** For each UPDATE change, the function checks if the target database
-** contains a row with the same primary key value (or values) as the
-** original row values stored in the changeset. If it does, and the values
-** stored in all modified non-primary key columns also match the values
-** stored in the changeset the row is updated within the target database.
-**
-** If a row with matching primary key values is found, but one or more of
-** the modified non-primary key fields contains a value different from an
-** original row value stored in the changeset, the conflict-handler function
-** is invoked with [SQLITE_CHANGESET_DATA] as the second argument. Since
-** UPDATE changes only contain values for non-primary key fields that are
-** to be modified, only those fields need to match the original values to
-** avoid the SQLITE_CHANGESET_DATA conflict-handler callback.
-**
-** If no row with matching primary key values is found in the database,
-** the conflict-handler function is invoked with [SQLITE_CHANGESET_NOTFOUND]
-** passed as the second argument.
-**
-** If the UPDATE operation is attempted, but SQLite returns
-** SQLITE_CONSTRAINT, the conflict-handler function is invoked with
-** [SQLITE_CHANGESET_CONSTRAINT] passed as the second argument.
-** This includes the case where the UPDATE operation is attempted after
-** an earlier call to the conflict handler function returned
-** [SQLITE_CHANGESET_REPLACE].
-**
-**
-** It is safe to execute SQL statements, including those that write to the
-** table that the callback related to, from within the xConflict callback.
-** This can be used to further customize the application's conflict
-** resolution strategy.
-**
-** All changes made by these functions are enclosed in a savepoint transaction.
-** If any other error (aside from a constraint failure when attempting to
-** write to the target database) occurs, then the savepoint transaction is
-** rolled back, restoring the target database to its original state, and an
-** SQLite error code returned.
-**
-** If the output parameters (ppRebase) and (pnRebase) are non-NULL and
-** the input is a changeset (not a patchset), then sqlite3changeset_apply_v2()
-** may set (*ppRebase) to point to a "rebase" that may be used with the

-** Changes within the local changeset are rebased as follows:
-**
-**
-** - Local INSERT
-
-** This may only conflict with a remote INSERT. If the conflict
-** resolution was OMIT, then add an UPDATE change to the rebased
-** changeset. Or, if the conflict resolution was REPLACE, add
-** nothing to the rebased changeset.
-**
-**
- Local DELETE
-
-** This may conflict with a remote UPDATE or DELETE. In both cases the
-** only possible resolution is OMIT. If the remote operation was a
-** DELETE, then add no change to the rebased changeset. If the remote
-** operation was an UPDATE, then the old.* fields of change are updated
-** to reflect the new.* values in the UPDATE.
-**
-**
- Local UPDATE
-
-** This may conflict with a remote UPDATE or DELETE. If it conflicts
-** with a DELETE, and the conflict resolution was OMIT, then the update
-** is changed into an INSERT. Any undefined values in the new.* record
-** from the update change are filled in using the old.* values from
-** the conflicting DELETE. Or, if the conflict resolution was REPLACE,
-** the UPDATE change is simply omitted from the rebased changeset.
-**
-** If conflict is with a remote UPDATE and the resolution is OMIT, then
-** the old.* values are rebased using the new.* values in the remote
-** change. Or, if the resolution is REPLACE, then the change is copied
-** into the rebased changeset with updates to columns also updated by
-** the conflicting remote UPDATE removed. If this means no columns would
-** be updated, the change is omitted.
-**
-**
-** A local change may be rebased against multiple remote changes
-** simultaneously. If a single key is modified by multiple remote
-** changesets, they are combined as follows before the local changeset
-** is rebased:
-**
-**
-** - If there has been one or more REPLACE resolutions on a
-** key, it is rebased according to a REPLACE.
-**
-**
- If there have been no REPLACE resolutions on a key, then
-** the local changeset is rebased according to the most recent
-** of the OMIT resolutions.
-**
-**
-** Note that conflict resolutions from multiple remote changesets are
-** combined on a per-field basis, not per-row. This means that in the
-** case of multiple remote UPDATE operations, some fields of a single
-** local change may be rebased for REPLACE while others are rebased for
-** OMIT.
-**
-** In order to rebase a local changeset, the remote changeset must first
-** be applied to the local database using sqlite3changeset_apply_v2() and
-** the buffer of rebase information captured. Then:
-**
-**
-** - An sqlite3_rebaser object is created by calling
-** sqlite3rebaser_create().
-**
- The new object is configured with the rebase buffer obtained from
-** sqlite3changeset_apply_v2() by calling sqlite3rebaser_configure().
-** If the local changeset is to be rebased against multiple remote
-** changesets, then sqlite3rebaser_configure() should be called
-** multiple times, in the same order that the multiple
-** sqlite3changeset_apply_v2() calls were made.
-**
- Each local changeset is rebased by calling sqlite3rebaser_rebase().
-**
- The sqlite3_rebaser object is deleted by calling
-** sqlite3rebaser_delete().

-** CAPI3REF: Streaming Versions of API functions.
-**
-** The six streaming API xxx_strm() functions serve similar purposes to the
-** corresponding non-streaming API functions:
-**
-**
-** | Streaming function | Non-streaming equivalent |
-**
|---|
| sqlite3changeset_apply_strm | [sqlite3changeset_apply]
-** | | sqlite3changeset_apply_strm_v2 | [sqlite3changeset_apply_v2]
-** | | sqlite3changeset_concat_strm | [sqlite3changeset_concat]
-** | | sqlite3changeset_invert_strm | [sqlite3changeset_invert]
-** | | sqlite3changeset_start_strm | [sqlite3changeset_start]
-** | | sqlite3session_changeset_strm | [sqlite3session_changeset]
-** | | sqlite3session_patchset_strm | [sqlite3session_patchset]
-** |
-**
-** Non-streaming functions that accept changesets (or patchsets) as input
-** require that the entire changeset be stored in a single buffer in memory.
-** Similarly, those that return a changeset or patchset do so by returning
-** a pointer to a single large buffer allocated using sqlite3_malloc().
-** Normally this is convenient. However, if an application running in a
-** low-memory environment is required to handle very large changesets, the
-** large contiguous memory allocations required can become onerous.
-**
-** In order to avoid this problem, instead of a single large buffer, input
-** is passed to a streaming API functions by way of a callback function that
-** the sessions module invokes to incrementally request input data as it is
-** required. In all cases, a pair of API function parameters such as
-**
-**
-** int nChangeset,
-** void *pChangeset,
-**
-**
-** Is replaced by:
-**
-**
-** int (*xInput)(void *pIn, void *pData, int *pnData),
-** void *pIn,
-**
-**
-** Each time the xInput callback is invoked by the sessions module, the first
-** argument passed is a copy of the supplied pIn context pointer. The second
-** argument, pData, points to a buffer (*pnData) bytes in size. Assuming no
-** error occurs the xInput method should copy up to (*pnData) bytes of data
-** into the buffer and set (*pnData) to the actual number of bytes copied
-** before returning SQLITE_OK. If the input is completely exhausted, (*pnData)
-** should be set to zero to indicate this. Or, if an error occurs, an SQLite
-** error code should be returned. In all cases, if an xInput callback returns
-** an error, all processing is abandoned and the streaming API function
-** returns a copy of the error code to the caller.
-**
-** In the case of sqlite3changeset_start_strm(), the xInput callback may be
-** invoked by the sessions module at any point during the lifetime of the
-** iterator. If such an xInput callback returns an error, the iterator enters
-** an error state, whereby all subsequent calls to iterator functions
-** immediately fail with the same error code as returned by xInput.
-**
-** Similarly, streaming API functions that return changesets (or patchsets)
-** return them in chunks by way of a callback function instead of via a
-** pointer to a single large buffer. In this case, a pair of parameters such
-** as:
-**
-**
-** int *pnChangeset,
-** void **ppChangeset,
-**
-**
-** Is replaced by:
-**
-**
-** int (*xOutput)(void *pOut, const void *pData, int nData),
-** void *pOut
-**
-**
-** The xOutput callback is invoked zero or more times to return data to
-** the application. The first parameter passed to each call is a copy of the
-** pOut pointer supplied by the application. The second parameter, pData,
-** points to a buffer nData bytes in size containing the chunk of output
-** data being returned. If the xOutput callback successfully processes the
-** supplied data, it should return SQLITE_OK to indicate success. Otherwise,
-** it should return some other SQLite error code. In this case processing
-** is immediately abandoned and the streaming API function returns a copy
-** of the xOutput error code to the application.
-**
-** The sessions module never invokes an xOutput callback with the third
-** parameter set to a value less than or equal to zero. Other than this,
-** no guarantees are made as to the size of the chunks of data returned.

-** EXTENSION API FUNCTIONS
-**
-** xUserData(pFts):
-** Return a copy of the context pointer the extension function was
-** registered with.
-**
-** xColumnTotalSize(pFts, iCol, pnToken):
-** If parameter iCol is less than zero, set output variable *pnToken
-** to the total number of tokens in the FTS5 table. Or, if iCol is
-** non-negative but less than the number of columns in the table, return
-** the total number of tokens in column iCol, considering all rows in
-** the FTS5 table.
-**
-** If parameter iCol is greater than or equal to the number of columns
-** in the table, SQLITE_RANGE is returned. Or, if an error occurs (e.g.
-** an OOM condition or IO error), an appropriate SQLite error code is
-** returned.
-**
-** xColumnCount(pFts):
-** Return the number of columns in the table.
-**
-** xColumnSize(pFts, iCol, pnToken):
-** If parameter iCol is less than zero, set output variable *pnToken
-** to the total number of tokens in the current row. Or, if iCol is
-** non-negative but less than the number of columns in the table, set
-** *pnToken to the number of tokens in column iCol of the current row.
-**
-** If parameter iCol is greater than or equal to the number of columns
-** in the table, SQLITE_RANGE is returned. Or, if an error occurs (e.g.
-** an OOM condition or IO error), an appropriate SQLite error code is
-** returned.
-**
-** This function may be quite inefficient if used with an FTS5 table
-** created with the "columnsize=0" option.
-**
-** xColumnText:
-** This function attempts to retrieve the text of column iCol of the
-** current document. If successful, (*pz) is set to point to a buffer
-** containing the text in utf-8 encoding, (*pn) is set to the size in bytes
-** (not characters) of the buffer and SQLITE_OK is returned. Otherwise,
-** if an error occurs, an SQLite error code is returned and the final values
-** of (*pz) and (*pn) are undefined.
-**
-** xPhraseCount:
-** Returns the number of phrases in the current query expression.
-**
-** xPhraseSize:
-** Returns the number of tokens in phrase iPhrase of the query. Phrases
-** are numbered starting from zero.
-**
-** xInstCount:
-** Set *pnInst to the total number of occurrences of all phrases within
-** the query within the current row. Return SQLITE_OK if successful, or
-** an error code (i.e. SQLITE_NOMEM) if an error occurs.
-**
-** This API can be quite slow if used with an FTS5 table created with the
-** "detail=none" or "detail=column" option. If the FTS5 table is created
-** with either "detail=none" or "detail=column" and "content=" option
-** (i.e. if it is a contentless table), then this API always returns 0.
-**
-** xInst:
-** Query for the details of phrase match iIdx within the current row.
-** Phrase matches are numbered starting from zero, so the iIdx argument
-** should be greater than or equal to zero and smaller than the value
-** output by xInstCount().
-**
-** Usually, output parameter *piPhrase is set to the phrase number, *piCol
-** to the column in which it occurs and *piOff the token offset of the
-** first token of the phrase. Returns SQLITE_OK if successful, or an error
-** code (i.e. SQLITE_NOMEM) if an error occurs.
-**
-** This API can be quite slow if used with an FTS5 table created with the
-** "detail=none" or "detail=column" option.
-**
-** xRowid:
-** Returns the rowid of the current row.
-**
-** xTokenize:
-** Tokenize text using the tokenizer belonging to the FTS5 table.
-**
-** xQueryPhrase(pFts5, iPhrase, pUserData, xCallback):
-** This API function is used to query the FTS table for phrase iPhrase
-** of the current query. Specifically, a query equivalent to:
-**
-** ... FROM ftstable WHERE ftstable MATCH $p ORDER BY rowid
-**
-** with $p set to a phrase equivalent to the phrase iPhrase of the
-** current query is executed. Any column filter that applies to
-** phrase iPhrase of the current query is included in $p. For each
-** row visited, the callback function passed as the fourth argument
-** is invoked. The context and API objects passed to the callback
-** function may be used to access the properties of each matched row.
-** Invoking Api.xUserData() returns a copy of the pointer passed as
-** the third argument to pUserData.
-**
-** If the callback function returns any value other than SQLITE_OK, the
-** query is abandoned and the xQueryPhrase function returns immediately.
-** If the returned value is SQLITE_DONE, xQueryPhrase returns SQLITE_OK.
-** Otherwise, the error code is propagated upwards.
-**
-** If the query runs to completion without incident, SQLITE_OK is returned.
-** Or, if some error occurs before the query completes or is aborted by
-** the callback, an SQLite error code is returned.
-**
-**
-** xSetAuxdata(pFts5, pAux, xDelete)
-**
-** Save the pointer passed as the second argument as the extension function's
-** "auxiliary data". The pointer may then be retrieved by the current or any
-** future invocation of the same fts5 extension function made as part of
-** the same MATCH query using the xGetAuxdata() API.
-**
-** Each extension function is allocated a single auxiliary data slot for
-** each FTS query (MATCH expression). If the extension function is invoked
-** more than once for a single FTS query, then all invocations share a
-** single auxiliary data context.
-**
-** If there is already an auxiliary data pointer when this function is
-** invoked, then it is replaced by the new pointer. If an xDelete callback
-** was specified along with the original pointer, it is invoked at this
-** point.
-**
-** The xDelete callback, if one is specified, is also invoked on the
-** auxiliary data pointer after the FTS5 query has finished.
-**
-** If an error (e.g. an OOM condition) occurs within this function,
-** the auxiliary data is set to NULL and an error code returned. If the
-** xDelete parameter was not NULL, it is invoked on the auxiliary data
-** pointer before returning.
-**
-**
-** xGetAuxdata(pFts5, bClear)
-**
-** Returns the current auxiliary data pointer for the fts5 extension
-** function. See the xSetAuxdata() method for details.
-**
-** If the bClear argument is non-zero, then the auxiliary data is cleared
-** (set to NULL) before this function returns. In this case the xDelete,
-** if any, is not invoked.
-**
-**
-** xRowCount(pFts5, pnRow)
-**
-** This function is used to retrieve the total number of rows in the table.
-** In other words, the same value that would be returned by:
-**
-** SELECT count(*) FROM ftstable;
-**
-** xPhraseFirst()
-** This function is used, along with type Fts5PhraseIter and the xPhraseNext
-** method, to iterate through all instances of a single query phrase within
-** the current row. This is the same information as is accessible via the
-** xInstCount/xInst APIs. While the xInstCount/xInst APIs are more convenient
-** to use, this API may be faster under some circumstances. To iterate
-** through instances of phrase iPhrase, use the following code:
-**
-** Fts5PhraseIter iter;
-** int iCol, iOff;
-** for(pApi->xPhraseFirst(pFts, iPhrase, &iter, &iCol, &iOff);
-** iCol>=0;
-** pApi->xPhraseNext(pFts, &iter, &iCol, &iOff)
-** ){
-** // An instance of phrase iPhrase at offset iOff of column iCol
-** }
-**
-** The Fts5PhraseIter structure is defined above. Applications should not
-** modify this structure directly - it should only be used as shown above
-** with the xPhraseFirst() and xPhraseNext() API methods (and by
-** xPhraseFirstColumn() and xPhraseNextColumn() as illustrated below).
-**
-** This API can be quite slow if used with an FTS5 table created with the
-** "detail=none" or "detail=column" option. If the FTS5 table is created
-** with either "detail=none" or "detail=column" and "content=" option
-** (i.e. if it is a contentless table), then this API always iterates
-** through an empty set (all calls to xPhraseFirst() set iCol to -1).
-**
-** xPhraseNext()
-** See xPhraseFirst above.
-**
-** xPhraseFirstColumn()
-** This function and xPhraseNextColumn() are similar to the xPhraseFirst()
-** and xPhraseNext() APIs described above. The difference is that instead
-** of iterating through all instances of a phrase in the current row, these
-** APIs are used to iterate through the set of columns in the current row
-** that contain one or more instances of a specified phrase. For example:
-**
-** Fts5PhraseIter iter;
-** int iCol;
-** for(pApi->xPhraseFirstColumn(pFts, iPhrase, &iter, &iCol);
-** iCol>=0;
-** pApi->xPhraseNextColumn(pFts, &iter, &iCol)
-** ){
-** // Column iCol contains at least one instance of phrase iPhrase
-** }
-**
-** This API can be quite slow if used with an FTS5 table created with the
-** "detail=none" option. If the FTS5 table is created with either
-** "detail=none" "content=" option (i.e. if it is a contentless table),
-** then this API always iterates through an empty set (all calls to
-** xPhraseFirstColumn() set iCol to -1).
-**
-** The information accessed using this API and its companion
-** xPhraseFirstColumn() may also be obtained using xPhraseFirst/xPhraseNext
-** (or xInst/xInstCount). The chief advantage of this API is that it is
-** significantly more efficient than those alternatives when used with
-** "detail=column" tables.
-**
-** xPhraseNextColumn()
-** See xPhraseFirstColumn above.

-** CUSTOM AUXILIARY FUNCTIONS
-*************************************************************************/
-
-/*************************************************************************
-** CUSTOM TOKENIZERS
-**
-** Applications may also register custom tokenizer types. A tokenizer
-** is registered by providing fts5 with a populated instance of the
-** following structure. All structure methods must be defined, setting
-** any member of the fts5_tokenizer struct to NULL leads to undefined
-** behaviour. The structure methods are expected to function as follows:
-**
-** xCreate:
-** This function is used to allocate and initialize a tokenizer instance.
-** A tokenizer instance is required to actually tokenize text.
-**
-** The first argument passed to this function is a copy of the (void*)
-** pointer provided by the application when the fts5_tokenizer object
-** was registered with FTS5 (the third argument to xCreateTokenizer()).
-** The second and third arguments are an array of nul-terminated strings
-** containing the tokenizer arguments, if any, specified following the
-** tokenizer name as part of the CREATE VIRTUAL TABLE statement used
-** to create the FTS5 table.
-**
-** The final argument is an output variable. If successful, (*ppOut)
-** should be set to point to the new tokenizer handle and SQLITE_OK
-** returned. If an error occurs, some value other than SQLITE_OK should
-** be returned. In this case, fts5 assumes that the final value of *ppOut
-** is undefined.
-**
-** xDelete:
-** This function is invoked to delete a tokenizer handle previously
-** allocated using xCreate(). Fts5 guarantees that this function will
-** be invoked exactly once for each successful call to xCreate().
-**
-** xTokenize:
-** This function is expected to tokenize the nText byte string indicated
-** by argument pText. pText may or may not be nul-terminated. The first
-** argument passed to this function is a pointer to an Fts5Tokenizer object
-** returned by an earlier call to xCreate().
-**
-** The second argument indicates the reason that FTS5 is requesting
-** tokenization of the supplied text. This is always one of the following
-** four values:
-**
-** - FTS5_TOKENIZE_DOCUMENT - A document is being inserted into
-** or removed from the FTS table. The tokenizer is being invoked to
-** determine the set of tokens to add to (or delete from) the
-** FTS index.
-**
-**
- FTS5_TOKENIZE_QUERY - A MATCH query is being executed
-** against the FTS index. The tokenizer is being called to tokenize
-** a bareword or quoted string specified as part of the query.
-**
-**
- (FTS5_TOKENIZE_QUERY | FTS5_TOKENIZE_PREFIX) - Same as
-** FTS5_TOKENIZE_QUERY, except that the bareword or quoted string is
-** followed by a "*" character, indicating that the last token
-** returned by the tokenizer will be treated as a token prefix.
-**
-**
- FTS5_TOKENIZE_AUX - The tokenizer is being invoked to
-** satisfy an fts5_api.xTokenize() request made by an auxiliary
-** function. Or an fts5_api.xColumnSize() request made by the same
-** on a columnsize=0 database.
-**
-**
-** For each token in the input string, the supplied callback xToken() must
-** be invoked. The first argument to it should be a copy of the pointer
-** passed as the second argument to xTokenize(). The third and fourth
-** arguments are a pointer to a buffer containing the token text, and the
-** size of the token in bytes. The 4th and 5th arguments are the byte offsets
-** of the first byte of and first byte immediately following the text from
-** which the token is derived within the input.
-**
-** The second argument passed to the xToken() callback ("tflags") should
-** normally be set to 0. The exception is if the tokenizer supports
-** synonyms. In this case see the discussion below for details.
-**
-** FTS5 assumes the xToken() callback is invoked for each token in the
-** order that they occur within the input text.
-**
-** If an xToken() callback returns any value other than SQLITE_OK, then
-** the tokenization should be abandoned and the xTokenize() method should
-** immediately return a copy of the xToken() return value. Or, if the
-** input buffer is exhausted, xTokenize() should return SQLITE_OK. Finally,
-** if an error occurs with the xTokenize() implementation itself, it
-** may abandon the tokenization and return any error code other than
-** SQLITE_OK or SQLITE_DONE.
-**
-** SYNONYM SUPPORT
-**
-** Custom tokenizers may also support synonyms. Consider a case in which a
-** user wishes to query for a phrase such as "first place". Using the
-** built-in tokenizers, the FTS5 query 'first + place' will match instances
-** of "first place" within the document set, but not alternative forms
-** such as "1st place". In some applications, it would be better to match
-** all instances of "first place" or "1st place" regardless of which form
-** the user specified in the MATCH query text.
-**
-** There are several ways to approach this in FTS5:
-**
-** - By mapping all synonyms to a single token. In this case, using
-** the above example, this means that the tokenizer returns the
-** same token for inputs "first" and "1st". Say that token is in
-** fact "first", so that when the user inserts the document "I won
-** 1st place" entries are added to the index for tokens "i", "won",
-** "first" and "place". If the user then queries for '1st + place',
-** the tokenizer substitutes "first" for "1st" and the query works
-** as expected.
-**
-**
- By querying the index for all synonyms of each query term
-** separately. In this case, when tokenizing query text, the
-** tokenizer may provide multiple synonyms for a single term
-** within the document. FTS5 then queries the index for each
-** synonym individually. For example, faced with the query:
-**
-**
-** ... MATCH 'first place'
-**
-** the tokenizer offers both "1st" and "first" as synonyms for the
-** first token in the MATCH query and FTS5 effectively runs a query
-** similar to:
-**
-**
-** ... MATCH '(first OR 1st) place'
-**
-** except that, for the purposes of auxiliary functions, the query
-** still appears to contain just two phrases - "(first OR 1st)"
-** being treated as a single phrase.
-**
-**
- By adding multiple synonyms for a single term to the FTS index.
-** Using this method, when tokenizing document text, the tokenizer
-** provides multiple synonyms for each token. So that when a
-** document such as "I won first place" is tokenized, entries are
-** added to the FTS index for "i", "won", "first", "1st" and
-** "place".
-**
-** This way, even if the tokenizer does not provide synonyms
-** when tokenizing query text (it should not - to do so would be
-** inefficient), it doesn't matter if the user queries for
-** 'first + place' or '1st + place', as there are entries in the
-** FTS index corresponding to both forms of the first token.
-**
-**
-** Whether it is parsing document or query text, any call to xToken that
-** specifies a tflags argument with the FTS5_TOKEN_COLOCATED bit
-** is considered to supply a synonym for the previous token. For example,
-** when parsing the document "I won first place", a tokenizer that supports
-** synonyms would call xToken() 5 times, as follows:
-**
-**
-** xToken(pCtx, 0, "i", 1, 0, 1);
-** xToken(pCtx, 0, "won", 3, 2, 5);
-** xToken(pCtx, 0, "first", 5, 6, 11);
-** xToken(pCtx, FTS5_TOKEN_COLOCATED, "1st", 3, 6, 11);
-** xToken(pCtx, 0, "place", 5, 12, 17);
-**
-**
-** It is an error to specify the FTS5_TOKEN_COLOCATED flag the first time
-** xToken() is called. Multiple synonyms may be specified for a single token
-** by making multiple calls to xToken(FTS5_TOKEN_COLOCATED) in sequence.
-** There is no limit to the number of synonyms that may be provided for a
-** single token.
-**
-** In many cases, method (1) above is the best approach. It does not add
-** extra data to the FTS index or require FTS5 to query for multiple terms,
-** so it is efficient in terms of disk space and query speed. However, it
-** does not support prefix queries very well. If, as suggested above, the
-** token "first" is substituted for "1st" by the tokenizer, then the query:
-**
-**
-** ... MATCH '1s*'
-**
-** will not match documents that contain the token "1st" (as the tokenizer
-** will probably not map "1s" to any prefix of "first").
-**
-** For full prefix support, method (3) may be preferred. In this case,
-** because the index contains entries for both "first" and "1st", prefix
-** queries such as 'fi*' or '1s*' will match correctly. However, because
-** extra entries are added to the FTS index, this method uses more space
-** within the database.
-**
-** Method (2) offers a midpoint between (1) and (3). Using this method,
-** a query such as '1s*' will match documents that contain the literal
-** token "1st", but not "first" (assuming the tokenizer is not able to
-** provide synonyms for prefixes). However, a non-prefix query like '1st'
-** will match against "1st" and "first". This method does not require
-** extra disk space, as no extra entries are added to the FTS index.
-** On the other hand, it may require more CPU cycles to run MATCH queries,
-** as separate queries of the FTS index are required for each synonym.
-**
-** When using methods (2) or (3), it is important that the tokenizer only
-** provide synonyms when tokenizing document text (method (2)) or query
-** text (method (3)), not both. Doing so will not cause any errors, but is
-** inefficient.

-** column of the b-tree of the cursor. The Expr tree will not contain
-** any function calls nor subqueries nor references to b-trees other than
-** the cursor being hinted.
-**
-** The design of the _RANGE hint is aid b-tree implementations that try
-** to prefetch content from remote machines - to provide those
-** implementations with limits on what needs to be prefetched and thereby
-** reduce network bandwidth.
-**
-** Note that BTREE_HINT_FLAGS with BTREE_BULKLOAD is the only hint used by

-** File Locking Notes: (Mostly about windows but also some info for Unix)
-**
-** We cannot use LockFileEx() or UnlockFileEx() on Win95/98/ME because
-** those functions are not available. So we use only LockFile() and
-** UnlockFile().
-**
-** LockFile() prevents not just writing but also reading by other processes.
-** A SHARED_LOCK is obtained by locking a single randomly-chosen
-** byte out of a specific range of bytes. The lock byte is obtained at
-** random so two separate readers can probably access the file at the
-** same time, unless they are unlucky and choose the same lock byte.
-** An EXCLUSIVE_LOCK is obtained by locking all bytes in the range.
-** There can only be one writer. A RESERVED_LOCK is obtained by locking
-** a single byte of the file that is designated as the reserved lock byte.
-** A PENDING_LOCK is obtained by locking a designated byte different from
-** the RESERVED_LOCK byte.
-**
-** On WinNT/2K/XP systems, LockFileEx() and UnlockFileEx() are available,
-** which means we can use reader/writer locks. When reader/writer locks
-** are used, the lock is placed on the same range of bytes that is used
-** for probabilistic locking in Win95/98/ME. Hence, the locking scheme
-** will support two or more Win95 readers or two or more WinNT readers.
-** But a single Win95 reader will lock out all WinNT readers and a single
-** WinNT reader will lock out all other Win95 readers.
-**
-** The following #defines specify the range of bytes used for locking.
-** SHARED_SIZE is the number of bytes available in the pool from which
-** a random byte is selected for a shared lock. The pool of bytes for
-** shared locks begins at SHARED_FIRST.
-**
-** The same locking strategy and
-** byte ranges are used for Unix. This leaves open the possibility of having
-** clients on win95, winNT, and unix all talking to the same shared file
-** and all locking correctly. To do so would require that samba (or whatever
-** tool is being used for file sharing) implements locks correctly between
-** windows and unix. I'm guessing that isn't likely to happen, but by
-** using the same locking range we are at least open to the possibility.
-**
-** Locking in windows is manditory. For this reason, we cannot store
-** actual data in the bytes used for locking. The pager never allocates
-** the pages involved in locking therefore. SHARED_SIZE is selected so
-** that all locks will fit on a single page even at the minimum page size.
-** PENDING_BYTE defines the beginning of the locks. By default PENDING_BYTE
-** is set high so that we don't have to allocate an unused page except
-** for very large databases. But one should test the page skipping logic
-** by setting PENDING_BYTE low and running the entire regression suite.
-**
-** Changing the value of PENDING_BYTE results in a subtly incompatible
-** file format. Depending on how it is changed, you might not notice
-** the incompatibility right away, even running a full regression test.
-** The default location of PENDING_BYTE is the first byte past the
-** 1GB boundary.

-** Lookaside malloc is a set of fixed-size buffers that can be used
-** to satisfy small transient memory allocation requests for objects
-** associated with a particular database connection. The use of
-** lookaside malloc provides a significant performance enhancement
-** (approx 10%) by avoiding numerous malloc/free requests while parsing
-** SQL statements.
-**
-** The Lookaside structure holds configuration information about the
-** lookaside malloc subsystem. Each available memory allocation in
-** the lookaside subsystem is stored on a linked list of LookasideSlot
-** objects.
-**
-** Lookaside allocations are only allowed for objects that are associated
-** with a particular database connection. Hence, schema information cannot
-** be stored in lookaside because in shared cache mode the schema information
-** is shared by multiple database connections. Therefore, while parsing
-** schema information, the Lookaside.bEnabled flag is cleared so that
-** lookaside allocations are not used to construct the schema objects.
-**
-** New lookaside allocations are only allowed if bDisable==0. When
-** bDisable is greater than zero, sz is set to zero which effectively
-** disables lookaside without adding a new test for the bDisable flag
-** in a performance-critical path. sz should be set by to szTrue whenever
-** bDisable changes back to zero.
-**
-** Lookaside buffers are initially held on the pInit list. As they are
-** used and freed, they are added back to the pFree list. New allocations
-** come off of pFree first, then pInit as a fallback. This dual-list
-** allows use to compute a high-water mark - the maximum number of allocations
-** outstanding at any point in the past - by subtracting the number of
-** allocations on the pInit list from the total number of allocations.
-**
-** Enhancement on 2019-12-12: Two-size-lookaside
-** The default lookaside configuration is 100 slots of 1200 bytes each.
-** The larger slot sizes are important for performance, but they waste
-** a lot of space, as most lookaside allocations are less than 128 bytes.
-** The two-size-lookaside enhancement breaks up the lookaside allocation
-** into two pools: One of 128-byte slots and the other of the default size
-** (1200-byte) slots. Allocations are filled from the small-pool first,
-** failing over to the full-size pool if that does not work. Thus more
-** lookaside slots are available while also using less memory.
-** This enhancement can be omitted by compiling with
-** SQLITE_OMIT_TWOSIZE_LOOKASIDE.

-** The following three macros, FUNCTION(), LIKEFUNC() and AGGREGATE() are
-** used to create the initializers for the FuncDef structures.
-**
-** FUNCTION(zName, nArg, iArg, bNC, xFunc)
-** Used to create a scalar function definition of a function zName
-** implemented by C function xFunc that accepts nArg arguments. The
-** value passed as iArg is cast to a (void*) and made available
-** as the user-data (sqlite3_user_data()) for the function. If
-** argument bNC is true, then the SQLITE_FUNC_NEEDCOLL flag is set.
-**
-** VFUNCTION(zName, nArg, iArg, bNC, xFunc)
-** Like FUNCTION except it omits the SQLITE_FUNC_CONSTANT flag.
-**
-** SFUNCTION(zName, nArg, iArg, bNC, xFunc)
-** Like FUNCTION except it omits the SQLITE_FUNC_CONSTANT flag and
-** adds the SQLITE_DIRECTONLY flag.
-**
-** INLINE_FUNC(zName, nArg, iFuncId, mFlags)
-** zName is the name of a function that is implemented by in-line
-** byte code rather than by the usual callbacks. The iFuncId
-** parameter determines the function id. The mFlags parameter is
-** optional SQLITE_FUNC_ flags for this function.
-**
-** TEST_FUNC(zName, nArg, iFuncId, mFlags)
-** zName is the name of a test-only function implemented by in-line
-** byte code rather than by the usual callbacks. The iFuncId
-** parameter determines the function id. The mFlags parameter is
-** optional SQLITE_FUNC_ flags for this function.
-**
-** DFUNCTION(zName, nArg, iArg, bNC, xFunc)
-** Like FUNCTION except it omits the SQLITE_FUNC_CONSTANT flag and
-** adds the SQLITE_FUNC_SLOCHNG flag. Used for date & time functions
-** and functions like sqlite_version() that can change, but not during
-** a single query. The iArg is ignored. The user-data is always set
-** to a NULL pointer. The bNC parameter is not used.
-**
-** MFUNCTION(zName, nArg, xPtr, xFunc)
-** For math-library functions. xPtr is an arbitrary pointer.
-**
-** PURE_DATE(zName, nArg, iArg, bNC, xFunc)
-** Used for "pure" date/time functions, this macro is like DFUNCTION
-** except that it does set the SQLITE_FUNC_CONSTANT flags. iArg is
-** ignored and the user-data for these functions is set to an
-** arbitrary non-NULL pointer. The bNC parameter is not used.
-**
-** AGGREGATE(zName, nArg, iArg, bNC, xStep, xFinal)
-** Used to create an aggregate function definition implemented by
-** the C functions xStep and xFinal. The first four parameters
-** are interpreted in the same way as the first 4 parameters to
-** FUNCTION().
-**
-** WFUNCTION(zName, nArg, iArg, xStep, xFinal, xValue, xInverse)
-** Used to create an aggregate function definition implemented by
-** the C functions xStep and xFinal. The first four parameters
-** are interpreted in the same way as the first 4 parameters to
-** FUNCTION().
-**
-** LIKEFUNC(zName, nArg, pArg, flags)
-** Used to create a scalar function definition of a function zName
-** that accepts nArg arguments and is implemented by a call to C
-** function likeFunc. Argument pArg is cast to a (void *) and made
-** available as the function user-data (sqlite3_user_data()). The
-** FuncDef.flags variable is set to the value passed as the flags
-** parameter.

-** An object of this type is created for each virtual table present in

-** If the database schema is shared, then there is one instance of this
-** structure for each database connection (sqlite3*) that uses the shared
-** schema. This is because each database connection requires its own unique
-** instance of the sqlite3_vtab* handle used to access the virtual table
-** implementation. sqlite3_vtab* handles can not be shared between
-** database connections, even when the rest of the in-memory database
-** schema is shared, as the implementation often stores the database
-** connection handle passed to it via the xConnect() or xCreate() method
-** during initialization internally. This database connection handle may
-** then be used by the virtual table implementation to access real tables
-** within the database. So that they appear as part of the callers
-** transaction, these accesses need to be made via the same database
-** connection as that used to execute SQL operations on the virtual table.
-**
-** All VTable objects that correspond to a single table in a shared
-** database schema are initially stored in a linked-list pointed to by
-** the Table.pVTable member variable of the corresponding Table object.
-** When an sqlite3_prepare() operation is required to access the virtual

-** sqlite3_vtab* handle in the compiled query.

-** deleted and the sqlite3_vtab* handles are not xDisconnect()ed
-** immediately. Instead, they are moved from the Table.pVTable list to
-** another linked list headed by the sqlite3.pDisconnect member of the
-** corresponding sqlite3 structure. They are then deleted/xDisconnected
-** next time a statement is prepared using said sqlite3*. This is done
-** to avoid deadlock issues involving multiple sqlite3.mutex mutexes.
-** Refer to comments above function sqlite3VtabUnlockList() for an

-** SQLite supports many different ways to resolve a constraint

-** changes due to the same operation are not backed out and no rollback
-** occurs. IGNORE means that the particular row that caused the constraint
-** error is not inserted or updated. Processing continues and no error
-** is returned. REPLACE means that preexisting database rows that caused
-** a UNIQUE constraint violation are removed so that the new insert or
-** update can proceed. Processing continues and no error is reported.
-** UPDATE applies to insert operations only and means that the insert
-** is omitted and the DO UPDATE clause of an upsert is run instead.

-** then Expr.token contains the name of the function.
-**
-** Expr.pRight and Expr.pLeft are the left and right subexpressions of a
-** binary operator. Either or both may be NULL.
-**
-** Expr.x.pList is a list of arguments if the expression is an SQL function,
-** a CASE expression or an IN expression of the form " IN (, ...)".
-** Expr.x.pSelect is used if the expression is a sub-select or an expression of

-** character '?' in the original SQL) then the Expr.iTable holds the index
-** number for that variable.
-**
-** If the expression is a subquery then Expr.iColumn holds an integer

-**
-** SRT_Discard Throw the results away. This is used by SELECT

-**
-** SRT_Output Generate a row of output (using the OP_ResultRow
-** opcode) for each row in the result set.
-**
-** SRT_Mem Only valid if the result is a single column.
-** Store the first column of the first result row
-** in register pDest->iSDParm then abandon the rest
-** of the query. This destination implies "LIMIT 1".
-**
-** SRT_Set The result must be a single column. Store each
-** row of result as the key in table pDest->iSDParm.
-** Apply the affinity pDest->affSdst before storing
-** results. Used to implement "IN (SELECT ...)".

-** SRT_EphemTab Create an temporary table pDest->iSDParm and store
-** the result there. The cursor is left open after
-** returning. This is like SRT_Table except that
-** this destination uses OP_OpenEphemeral to create
-** the table first.

-** and the result row is stored in pDest->nDest registers
-** starting with pDest->iSdst.
-**
-** SRT_Table Store results in temporary table pDest->iSDParm.
-** SRT_Fifo This is like SRT_EphemTab except that the table
-** is assumed to already be open. SRT_Fifo has
-** the additional property of being able to ignore
-** the ORDER BY clause.
-**
-** SRT_DistFifo Store results in a temporary table pDest->iSDParm.
-** But also use temporary table pDest->iSDParm+1 as
-** a record of all prior results and ignore any duplicate
-** rows. Name means: "Distinct Fifo".
-**
-** SRT_Queue Store results in priority queue pDest->iSDParm (really
-** an index). Append a sequence number so that all entries
-** are distinct.
-**
-** SRT_DistQueue Store results in priority queue pDest->iSDParm only if
-** the same record has never been stored before. The
-** index at pDest->iSDParm+1 hold all prior stores.
-**
-** SRT_Upfrom Store results in the temporary table already opened by
-** pDest->iSDParm. If (pDest->iSDParm<0), then the temp
-** table is an intkey table - in this case the first
-** column returned by the SELECT is used as the integer
-** key. If (pDest->iSDParm>0), then the table is an index
-** table. (pDest->iSDParm) is the number of key columns in

-** This file contains the C functions that implement date and time

-**
-** There is only one exported symbol in this file - the function
-** sqlite3RegisterDateTimeFunctions() found at the bottom of the file.
-** All other code has file scope.
-**
-** SQLite processes all times and dates as julian day numbers. The
-** dates and times are stored as the number of days since noon
-** in Greenwich on November 24, 4714 B.C. according to the Gregorian
-** calendar system.
-**
-** 1970-01-01 00:00:00 is JD 2440587.5
-** 2000-01-01 00:00:00 is JD 2451544.5
-**
-** This implementation requires years to be expressed as a 4-digit number
-** which means that only dates between 0000-01-01 and 9999-12-31 can
-** be represented, even though julian day numbers allow a much wider
-** range of dates.
-**
-** The Gregorian calendar system is used for all dates and times,
-** even those that predate the Gregorian calendar. Historians usually
-** use the julian calendar for dates prior to 1582-10-15 and for some
-** dates afterwards, depending on locale. Beware of this difference.
-**
-** The conversion algorithms are implemented based on descriptions
-** in the following text:

-*************************************************************************
-** This file contains the C functions that implement a memory
-** allocation subsystem for use by SQLite.
-**
-** This version of the memory allocation subsystem omits all
-** use of malloc(). The application gives SQLite a block of memory
-** before calling sqlite3_initialize() from which allocations
-** are made and returned by the xMalloc() and xRealloc()
-** implementations. Once sqlite3_initialize() has been called,
-** the amount of memory available to SQLite is fixed and cannot
-** be changed.
-**
-** This version of the memory allocation subsystem is included
-** in the build only if SQLITE_ENABLE_MEMSYS5 is defined.
-**
-** This memory allocator uses the following algorithm:
-**
-** 1. All memory allocation sizes are rounded up to a power of 2.
-**
-** 2. If two adjacent free blocks are the halves of a larger block,
-** then the two blocks are coalesced into the single larger block.
-**
-** 3. New memory is allocated from the first available free block.
-**
-** This algorithm is described in: J. M. Robson. "Bounds for Some Functions
-** Concerning Dynamic Storage Allocation". Journal of the Association for
-** Computing Machinery, Volume 21, Number 8, July 1974, pages 491-499.
-**
-** Let n be the size of the largest allocation divided by the minimum
-** allocation size (after rounding all sizes up to a power of 2.) Let M
-** be the maximum amount of memory ever outstanding at one time. Let
-** N be the total amount of memory available for allocation. Robson
-** proved that this memory allocator will never breakdown due to
-** fragmentation as long as the following constraint holds:
-**
-** N >= M*(1 + log2(n)/2) - n + 1
-**
-** The sqlite3_status() logic tracks the maximum values of n and M so
-** that an application can, at any time, verify this constraint.

-** The first two constants cause sqlite3_mutex_alloc() to create
-** a new mutex. The new mutex is recursive when SQLITE_MUTEX_RECURSIVE
-** is used but not necessarily so when SQLITE_MUTEX_FAST is used.
-** The mutex implementation does not need to make a distinction
-** between SQLITE_MUTEX_RECURSIVE and SQLITE_MUTEX_FAST if it does
-** not want to. But SQLite will only request a recursive mutex in
-** cases where it really needs one. If a faster non-recursive mutex
-** implementation is available on the host platform, the mutex subsystem
-** might return such a mutex in response to SQLITE_MUTEX_FAST.
-**
-** The other allowed parameters to sqlite3_mutex_alloc() each return
-** a pointer to a static preexisting mutex. Six static mutexes are
-** used by the current version of SQLite. Future versions of SQLite
-** may add additional static mutexes. Static mutexes are for internal
-** use by SQLite only. Applications that use SQLite mutexes should
-** use only the dynamic mutexes returned by SQLITE_MUTEX_FAST or
-** SQLITE_MUTEX_RECURSIVE.
-**
-** Note that if one of the dynamic mutex parameters (SQLITE_MUTEX_FAST
-** or SQLITE_MUTEX_RECURSIVE) is used then sqlite3_mutex_alloc()
-** returns a different mutex on every call. But for the static
-** mutex types, the same mutex is returned on every call that has
-** the same type number.
