-** in the name of the object stands for "virtual file system".
-**
-** The iVersion field is initially 1 but may be larger for future
-** versions of SQLite. Additional fields may be appended to this
-** object when the iVersion value is 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 vfs modules 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.
-**
-** The pNext field is the only fields 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.
-**
-** {F11141} SQLite will guarantee that the zFilename string passed to
-** xOpen() is a full pathname as generated by xFullPathname() and
-** that the string will be valid and unchanged until xClose() is
-** called. {END} So the [sqlite3_file] can store a pointer to the
-** filename if it needs to remember the filename for some reason.
-**
-** {F11142} 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]. {END}
-** If xOpen() opens a file read-only then it sets *pOutFlags to
-** include [SQLITE_OPEN_READONLY]. Other bits in *pOutFlags may be
-** set.
-**
-** {F11143} SQLite will also add one of the following flags to the xOpen()
-** call, depending on the object being opened:
-**
-** <ul>
-** <li> [SQLITE_OPEN_MAIN_DB]
-** <li> [SQLITE_OPEN_MAIN_JOURNAL]
-** <li> [SQLITE_OPEN_TEMP_DB]

-** <li> [SQLITE_OPEN_SUBJOURNAL]
-** <li> [SQLITE_OPEN_MASTER_JOURNAL]
-** </ul> {END}
-**
-** The file I/O implementation can use the object type flags to
-** changes 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 are
-** also a no-op. Any attempt to read the journal return SQLITE_IOERR.
-** Or the implementation might recognize the a database file will
-** be doing page-aligned sector reads and writes in a random order
-** and set up its I/O subsystem accordingly.
-**
-** {F11144} SQLite might also add one of the following flags to the xOpen
-** method:
-**
-** <ul>
-** <li> [SQLITE_OPEN_DELETEONCLOSE]
-** <li> [SQLITE_OPEN_EXCLUSIVE]
-** </ul>
-**
-** {F11145} The [SQLITE_OPEN_DELETEONCLOSE] flag means the file should be
-** deleted when it is closed. {F11146} The [SQLITE_OPEN_DELETEONCLOSE]
-** will be set for TEMP databases, journals and for subjournals.
-** {F11147} The [SQLITE_OPEN_EXCLUSIVE] flag means the file should be opened
-** for exclusive access. This flag is set for all files except
-** for the main database file. {END}
-**
-** {F11148} At least szOsFile bytes of memory is allocated by SQLite
-** to hold the [sqlite3_file] structure passed as the third
-** argument to xOpen. {END} The xOpen method does not have to
-** allocate the structure; it should just fill it in.
-**
-** {F11149} The flags argument to xAccess() may be [SQLITE_ACCESS_EXISTS]
-** to test for the existance of a file,
-** or [SQLITE_ACCESS_READWRITE] to test to see
-** if a file is readable and writable, or [SQLITE_ACCESS_READ]
-** to test to see if a file is at least readable. {END} The file can be a
-** directory.
-**
-** {F11150} SQLite will always allocate at least mxPathname+1 byte for
-** the output buffers for xGetTempname and xFullPathname. {F11151} The exact

-** mxPathname to a sufficiently large value.
-**
-** The xRandomness(), xSleep(), and xCurrentTime() interfaces

-** the second process to proceed.

-** {F12321} The default busy callback is NULL. {END}

-** already hold a RESERVED lock on the database file, but it needs
-** to promote this lock to EXCLUSIVE so that it can spill cache
-** pages into the database file without harm to concurrent
-** readers. {F12324} If it is unable to promote the lock, then the in-memory
-** cache will be left in an inconsistent state and so the error
-** code is promoted from the relatively benign [SQLITE_BUSY] to

-**
-** These routines are workalikes of the "printf()" family of functions

-**

-** results into memory obtained from [sqlite3_malloc()].
-** {U17402} The strings returned by these two routines should be
-** released by [sqlite3_free()]. {F17403} Both routines return a
-** NULL pointer if [sqlite3_malloc()] is unable to allocate enough
-** memory to hold the resulting string.
-**
-** {F17404} In sqlite3_snprintf() routine is similar to "snprintf()" from
-** the standard C library. The result is written into the
-** buffer supplied as the second parameter whose size is given by
-** the first parameter. {END} Note that the order of the
-** first two parameters is reversed from snprintf(). This is an
-** historical accident that cannot be fixed without breaking
-** backwards compatibility. {F17405} Note also that sqlite3_snprintf()
-** returns a pointer to its buffer instead of the number of
-** characters actually written into the buffer. {END} We admit that
-** the number of characters written would be a more useful return
-** value but we cannot change the implementation of sqlite3_snprintf()
-** now without breaking compatibility.
-**
-** {F17406} As long as the buffer size is greater than zero, sqlite3_snprintf()
-** guarantees that the buffer is always zero-terminated. {F17407} The first
-** parameter "n" is the total size of the buffer, including space for
-** the zero terminator. {END} So the longest string that can be completely
-** written will be n-1 characters.
-**
-** These routines all implement some additional formatting
-** options that are useful for constructing SQL statements.
-** All of the usual printf formatting options apply. In addition, there
-** is are "%q", "%Q", and "%z" options.
-**
-** {F17410} The %q option works like %s in that it substitutes a null-terminated
-** string from the argument list. But %q also doubles every '\'' character.
-** %q is designed for use inside a string literal. {END} By doubling each '\''
-** character it escapes that character and allows it to be inserted into
-** the string.
-**
-** For example, so some string variable contains text as follows:
-**
-** <blockquote><pre>
-** char *zText = "It's a happy day!";
-** </pre></blockquote>
-**
-** One can use this text in an SQL statement as follows:
-**
-** <blockquote><pre>
-** char *zSQL = sqlite3_mprintf("INSERT INTO table VALUES('%q')", zText);
-** sqlite3_exec(db, zSQL, 0, 0, 0);
-** sqlite3_free(zSQL);
-** </pre></blockquote>
-**
-** Because the %q format string is used, the '\'' character in zText
-** is escaped and the SQL generated is as follows:
-**
-** <blockquote><pre>
-** INSERT INTO table1 VALUES('It''s a happy day!')
-** </pre></blockquote>
-**
-** This is correct. Had we used %s instead of %q, the generated SQL
-** would have looked like this:
-**
-** <blockquote><pre>
-** INSERT INTO table1 VALUES('It's a happy day!');
-** </pre></blockquote>
-**
-** This second example is an SQL syntax error. As a general rule you
-** should always use %q instead of %s when inserting text into a string
-** literal.
-**
-** {F17411} The %Q option works like %q except it also adds single quotes around
-** the outside of the total string. Or if the parameter in the argument
-** list is a NULL pointer, %Q substitutes the text "NULL" (without single
-** quotes) in place of the %Q option. {END} So, for example, one could say:
-**
-** <blockquote><pre>
-** char *zSQL = sqlite3_mprintf("INSERT INTO table VALUES(%Q)", zText);
-** sqlite3_exec(db, zSQL, 0, 0, 0);
-** sqlite3_free(zSQL);
-** </pre></blockquote>
-**
-** The code above will render a correct SQL statement in the zSQL
-** variable even if the zText variable is a NULL pointer.
-**
-** {F17412} The "%z" formatting option works exactly like "%s" with the
-** addition that after the string has been read and copied into
-** the result, [sqlite3_free()] is called on the input string. {END}

-** a NULL pointer.
-**
-** {F17305} Calling sqlite3_free() with a pointer previously returned

-** {F17312} If the second parameter to sqlite3_realloc() is zero or

-** {F17313} Sqlite3_realloc() returns a pointer to a memory allocation
-** of at least N bytes in size or NULL if sufficient memory is unavailable.
-** {F17314} 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

-** is not freed.
-**
-** {F17316} The memory returned by sqlite3_malloc() and sqlite3_realloc()

-**
-** {F17381} The default implementation

-** in the native byte order for [sqlite3_open16()].
-** {F12703} An [sqlite3*] handle is returned in *ppDb, even
-** if an error occurs. {F12723} (Exception: if SQLite is unable
-** to allocate memory to hold the [sqlite3] object, a NULL will
-** be written into *ppDb instead of a pointer to the [sqlite3] object.)
-** {F12704} If the database is opened (and/or created)
-** successfully, then [SQLITE_OK] is returned. {F12705} Otherwise an
-** error code is returned. {F12706} The
-** [sqlite3_errmsg()] or [sqlite3_errmsg16()] routines can be used to obtain
-** an English language description of the error.
-**
-** {F12707} The default encoding for the database will be UTF-8 if
-** [sqlite3_open()] or [sqlite3_open_v2()] is called and
-** UTF-16 in the native byte order if [sqlite3_open16()] is used.
-**
-** {F12708} Whether or not an error occurs when it is opened, resources
-** associated with the [sqlite3*] handle should be released by passing it
-** to [sqlite3_close()] when it is no longer required.
-**
-** {F12709} The [sqlite3_open_v2()] interface works like [sqlite3_open()]
-** except that it acccepts two additional parameters for additional control
-** over the new database connection. {F12710} The flags parameter can be
-** one of:

-** <li> [SQLITE_OPEN_READONLY]
-** <li> [SQLITE_OPEN_READWRITE]
-** <li> [SQLITE_OPEN_READWRITE] | [SQLITE_OPEN_CREATE]
-** </ol>
-**
-** {F12711} The first value opens the database read-only.
-** {F12712} If the database does not previously exist, an error is returned.
-** {F12713} The second option opens
-** the database for reading and writing if possible, or reading only if
-** if the file is write protected. {F12714} In either case the database
-** must already exist or an error is returned. {F12715} The third option
-** opens the database for reading and writing and creates it if it does
-** not already exist. {F12716}
-** The third options is behavior that is always used for [sqlite3_open()]
-** and [sqlite3_open16()].
-**
-** {F12717} If the filename is ":memory:", then an private
-** in-memory database is created for the connection. {F12718} This in-memory
-** database will vanish when the database connection is closed. {END} Future
-** version of SQLite might make use of additional special filenames
-** that begin with the ":" character. It is recommended that
-** when a database filename really does begin with
-** ":" that you prefix the filename with a pathname like "./" to
-** avoid ambiguity.
-**
-** {F12719} If the filename is an empty string, then a private temporary

-** use UTF-16. {END}
-**
-** {F13013} If the nByte argument is less

-** {F13014} If nByte is non-negative, then it is the maximum number of

-** until the nByte-th byte, whichever comes first. {END}
-**
-** {F13015} *pzTail is made to point to the first byte past the end of the

-** statement in zSql, so *pzTail is left pointing to what remains

-**
-** {F13016} *ppStmt is left pointing to a compiled
-** [sqlite3_stmt | SQL statement structure] that can be
-** executed using [sqlite3_step()]. Or if there is an error, *ppStmt may be
-** set to NULL. {F13017} If the input text contains no SQL (if the input

-**
-** After an [sqlite3_stmt | SQL statement] has been prepared with a call
-** to either [sqlite3_prepare_v2()] or [sqlite3_prepare16_v2()] or to one of
-** the legacy interfaces [sqlite3_prepare()] or [sqlite3_prepare16()],
-** then this function must be called one or more times to evaluate the
-** statement.
-**
-** The details of the behavior of this sqlite3_step() interface depend
-** on whether the statement was prepared using the newer "v2" interface
-** [sqlite3_prepare_v2()] and [sqlite3_prepare16_v2()] or the older legacy
-** interface [sqlite3_prepare()] and [sqlite3_prepare16()]. The use of the
-** new "v2" interface is recommended for new applications but the legacy
-** interface will continue to be supported.
-**
-** In the lagacy 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 [SQLITE_OK | result code]
-** or [SQLITE_IOERR_READ | extended result code] 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 a
-** 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 [sqlite3_column_int | 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 (example:
-** [SQLITE_INTERRUPT], [SQLITE_SCHEMA], [SQLITE_CORRUPT], and so forth)
-** can be obtained by calling [sqlite3_reset()] on the
-** [sqlite3_stmt | 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 [sqlite3_stmt | 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.
-**
-** <b>Goofy Interface Alert:</b>
-** 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
-** [SQLITE_ERROR | result 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 either [sqlite3_prepare_v2()] or [sqlite3_prepare16_v2()] instead
-** of the legacy [sqlite3_prepare()] and [sqlite3_prepare16()], then the
-** more specific [SQLITE_ERROR | result codes] are returned directly

-**
-** If the SQL statement is not currently point to a valid row, or if the
-** 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()] has been call subsequently.
-** If any of these routines are called after [sqlite3_reset()] or

-** 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 sqlite3_column_type() routine returns
-** [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 value
-** returned by sqlite3_column_type() is only meaningful if no type
-** conversions have occurred as described below. After a type conversion,
-** the value returned by sqlite3_column_type() is undefined. Future
-** versions of SQLite may change the behavior of sqlite3_column_type()
-** following a type conversion.
-**
-** 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.
-** The value returned does not include the zero terminator at the end
-** of the string. For clarity: the value returned is the number of
-** bytes in the string, not the number of characters.
-**
-** Strings returned by sqlite3_column_text() and sqlite3_column_text16(),
-** even zero-length strings, are always zero terminated. The return
-** value from sqlite3_column_blob() for a zero-length blob is an arbitrary
-** pointer, possibly even a NULL pointer.
-**
-** The sqlite3_column_bytes16() routine is similar to sqlite3_column_bytes()
-** but leaves the result in UTF-16 instead of UTF-8.
-** The zero terminator is not included in this count.
-**
-** These routines attempt to convert the value where appropriate. For
-** example, if the internal representation is FLOAT and a text result
-** is requested, [sqlite3_snprintf()] is used internally to do the conversion
-** automatically. The following table details the conversions that
-** are applied:
-**
-** <blockquote>
-** <table border="1">
-** <tr><th> Internal<br>Type <th> Requested<br>Type <th> Conversion
-**
-** <tr><td> NULL <td> INTEGER <td> Result is 0
-** <tr><td> NULL <td> FLOAT <td> Result is 0.0
-** <tr><td> NULL <td> TEXT <td> Result is NULL pointer
-** <tr><td> NULL <td> BLOB <td> Result is NULL pointer
-** <tr><td> INTEGER <td> FLOAT <td> Convert from integer to float
-** <tr><td> INTEGER <td> TEXT <td> ASCII rendering of the integer
-** <tr><td> INTEGER <td> BLOB <td> Same as for INTEGER->TEXT
-** <tr><td> FLOAT <td> INTEGER <td> Convert from float to integer
-** <tr><td> FLOAT <td> TEXT <td> ASCII rendering of the float
-** <tr><td> FLOAT <td> BLOB <td> Same as FLOAT->TEXT
-** <tr><td> TEXT <td> INTEGER <td> Use atoi()
-** <tr><td> TEXT <td> FLOAT <td> Use atof()
-** <tr><td> TEXT <td> BLOB <td> No change
-** <tr><td> BLOB <td> INTEGER <td> Convert to TEXT then use atoi()
-** <tr><td> BLOB <td> FLOAT <td> Convert to TEXT then use atof()
-** <tr><td> BLOB <td> TEXT <td> Add a zero terminator if needed
-** </table>
-** </blockquote>
-**
-** The table above makes reference to standard C library functions atoi()
-** and atof(). SQLite does not really use these functions. It has its
-** on equavalent internal routines. The atoi() and atof() names are
-** used in the table for brevity and because they are familiar to most
-** C programmers.
-**
-** 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:
-**
-** <ul>
-** <li><p> 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.</p></li>
-**
-** <li><p> 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.</p></li>
-**
-** <li><p> 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.</p></li>
-** </ul>
-**
-** 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 points to will have been modified. Other kinds
-** of conversion are done in place when it is possible, but sometime it is
-** not possible and in those cases prior pointers are invalidated.
-**
-** The safest and easiest to remember policy is to invoke these routines
-** in one of the following ways:
-**
-** <ul>
-** <li>sqlite3_column_text() followed by sqlite3_column_bytes()</li>
-** <li>sqlite3_column_blob() followed by sqlite3_column_bytes()</li>
-** <li>sqlite3_column_text16() followed by sqlite3_column_bytes16()</li>
-** </ul>
-**
-** 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 call 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 <b>not</b> pass the pointers returned
-** [sqlite3_column_blob()], [sqlite3_column_text()], etc. into
-** [sqlite3_free()].
-**
-** If a memory allocation error occurs during the evaluation of any
-** of these routines, a default value is returned. The default value
-** is either the integer 0, the floating point number 0.0, or a NULL
-** pointer. Subsequent calls to [sqlite3_errcode()] will return
-** [SQLITE_NOMEM].

-** The first argument is the [sqlite3 | database handle] that holds the

-**
-** 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, exclusive of the
-** zero-terminator. Note that the name length limit is in bytes, not
-** characters. Any attempt to create a function with a longer name
-** will result in an SQLITE_ERROR error.
-**
-** The third parameter is the number of arguments that the SQL function or
-** aggregate takes. If this parameter is negative, then the SQL function or
-** aggregate may take any number of arguments.
-**
-** The fourth parameter, eTextRep, specifies what
-** [SQLITE_UTF8 | text encoding] this SQL function prefers for
-** its parameters. Any SQL function implementation should be able to work
-** work with UTF-8, UTF-16le, or UTF-16be. But some implementations may be

-** times with the same function but with different values of eTextRep.
-** When multiple implementations of the same function are available, SQLite
-** will pick the one that involves the least amount of data conversion.
-** If there is only a single implementation which does not care what
-** text encoding is used, then the fourth argument should be
-** [SQLITE_ANY].
-**
-** The fifth parameter is an arbitrary pointer. The implementation
-** of the function can gain access to this pointer using

-**
-** The xFunc (for scalar functions) or xStep (for aggregates) parameters
-** to [sqlite3_create_function()] and [sqlite3_create_function16()]
-** define callbacks that implement the SQL functions and aggregates.
-** The 4th parameter to these callbacks is an array of pointers to
-** [sqlite3_value] objects. There is one [sqlite3_value] object for
-** each parameter to the SQL function. These routines are used to
-** extract values from the [sqlite3_value] objects.
-**
-** These routines work just like the corresponding
-** [sqlite3_column_blob | sqlite3_column_* routines] except that
-** these routines take a single [sqlite3_value*] pointer instead
-** of an [sqlite3_stmt*] pointer and an integer column number.
-**
-** The sqlite3_value_text16() interface extracts a UTF16 string
-** in the native byte-order of the host machine. The
-** sqlite3_value_text16be() and sqlite3_value_text16le() interfaces
-** extract UTF16 strings as big-endian and little-endian respectively.
-**
-** 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 done. Otherwise no conversion occurs. The
-** [SQLITE_INTEGER | datatype] after conversion is returned.
-**
-** Please pay particular attention to the fact that the pointer that

-**
-** These functions work very much like the

-** to bind values to host parameters in prepared statements.
-** Refer to the
-** [sqlite3_bind_blob | sqlite3_bind_* documentation] for
-** additional information.
-**
-** {F16402} The sqlite3_result_blob() interface sets the result from

-** to by the second parameter and which is N bytes long where N is the
-** third parameter.
-** {F16403} The sqlite3_result_zeroblob() inerfaces set the result of
-** the application defined function to be a BLOB containing all zero
-** bytes and N bytes in size, where N is the value of the 2nd parameter.
-**
-** {F16407} The sqlite3_result_double() interface sets the result from
-** an application defined function to be a floating point value specified
-** by its 2nd argument.
-**
-** {F16409} The sqlite3_result_error() and sqlite3_result_error16() functions
-** cause the implemented SQL function to throw an exception.
-** {F16411} 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. {F16412} SQLite interprets the error
-** message string from sqlite3_result_error() as UTF8. {F16413} SQLite
-** interprets the string from sqlite3_result_error16() as UTF16 in native
-** byte order. {F16414} If the third parameter to sqlite3_result_error()
-** or sqlite3_result_error16() is negative then SQLite takes as the error

-** {F16417} The sqlite3_result_error() and sqlite3_result_error16()
-** routines make a copy private copy of the error message text before
-** they return. {END} Hence, the calling function can deallocate or
-** modify the text after they return without harm.
-**
-** {F16421} The sqlite3_result_toobig() interface causes SQLite
-** to throw an error indicating that a string or BLOB is to long
-** to represent. {F16422} The sqlite3_result_nomem() interface
-** causes SQLite to throw an exception indicating that the a
-** memory allocation failed.
-**
-** {F16431} 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.
-** {F16432} 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.
-**
-** {F16437} The sqlite3_result_null() interface sets the return value

-**
-** {F16441} 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.
-** {F16442} SQLite takes the text result from the application from
-** the 2nd parameter of the sqlite3_result_text* interfaces.
-** {F16444} 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.
-** {F16447} 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.
-** {F16451} 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.
-** {F16453} If the 4th parameter to the sqlite3_result_text* interfaces
-** or sqlite3_result_blob is the special constant SQLITE_STATIC, then
-** SQLite assumes that the text or blob result is constant space and
-** does not copy the space or call a destructor when it has
-** finished using that result.
-** {F16454} 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

-** 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:
-**
-** <ul>
-** <li> SQLITE_MUTEX_OS2
-** <li> SQLITE_MUTEX_PTHREAD
-** <li> SQLITE_MUTEX_W32
-** <li> SQLITE_MUTEX_NOOP
-** </ul>
-**
-** 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_OS2,
-** SQLITE_MUTEX_PTHREAD, and SQLITE_MUTEX_W32 implementations
-** are appropriate for use on os/2, 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. The
-** mutex interface routines defined here become external
-** references in the SQLite library for which implementations
-** must be provided by the application. This facility allows an
-** application that links against SQLite to provide its own mutex
-** implementation without having to modify the SQLite core.
-**
-** {F17011} The sqlite3_mutex_alloc() routine allocates a new
-** mutex and returns a pointer to it. {F17012} If it returns NULL
-** that means that a mutex could not be allocated. {F17013} SQLite
-** will unwind its stack and return an error. {F17014} The argument
-** to sqlite3_mutex_alloc() is one of these integer constants:
-**
-** <ul>
-** <li> SQLITE_MUTEX_FAST
-** <li> SQLITE_MUTEX_RECURSIVE
-** <li> SQLITE_MUTEX_STATIC_MASTER
-** <li> SQLITE_MUTEX_STATIC_MEM
-** <li> SQLITE_MUTEX_STATIC_MEM2
-** <li> SQLITE_MUTEX_STATIC_PRNG
-** <li> SQLITE_MUTEX_STATIC_LRU
-** </ul> {END}
-**
-** {F17015} 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. {END}
-** The mutex implementation does not need to make a distinction
-** between SQLITE_MUTEX_RECURSIVE and SQLITE_MUTEX_FAST if it does
-** not want to. {F17016} But SQLite will only request a recursive mutex in
-** cases where it really needs one. {END} 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.
-**
-** {F17017} The other allowed parameters to sqlite3_mutex_alloc() each return
-** a pointer to a static preexisting mutex. {END} Four 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.
-**
-** {F17018} 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. {F17034} But for the static
-** mutex types, the same mutex is returned on every call that has
-** the same type number. {END}
-**
-** {F17019} The sqlite3_mutex_free() routine deallocates a previously
-** allocated dynamic mutex. {F17020} SQLite is careful to deallocate every
-** dynamic mutex that it allocates. {U17021} The dynamic mutexes must not be in
-** use when they are deallocated. {U17022} Attempting to deallocate a static
-** mutex results in undefined behavior. {F17023} SQLite never deallocates
-** a static mutex. {END}
-**
-** The sqlite3_mutex_enter() and sqlite3_mutex_try() routines attempt
-** to enter a mutex. {F17024} If another thread is already within the mutex,
-** sqlite3_mutex_enter() will block and sqlite3_mutex_try() will return
-** SQLITE_BUSY. {F17025} The sqlite3_mutex_try() interface returns SQLITE_OK
-** upon successful entry. {F17026} Mutexes created using
-** SQLITE_MUTEX_RECURSIVE can be entered multiple times by the same thread.
-** {F17027} In such cases the,
-** mutex must be exited an equal number of times before another thread
-** can enter. {U17028} If the same thread tries to enter any other
-** kind of mutex more than once, the behavior is undefined.
-** {F17029} SQLite will never exhibit
-** such behavior in its own use of mutexes. {END}
-**
-** Some systems (ex: windows95) do not the operation implemented by
-** sqlite3_mutex_try(). On those systems, sqlite3_mutex_try() will
-** always return SQLITE_BUSY. {F17030} The SQLite core only ever uses
-** sqlite3_mutex_try() as an optimization so this is acceptable behavior. {END}
-**
-** {F17031} The sqlite3_mutex_leave() routine exits a mutex that was
-** previously entered by the same thread. {U17032} The behavior
-** is undefined if the mutex is not currently entered by the
-** calling thread or is not currently allocated. {F17033} SQLite will
-** never do either. {END}

+**
+** {F17404} In sqlite3_snprintf() routine is similar to "snprintf()" from
+** the standard C library. The result is written into the
+** buffer supplied as the second parameter whose size is given by
+** the first parameter. {END} Note that the order of the

+** historical accident that cannot be fixed without breaking
+** backwards compatibility. {F17405} Note also that sqlite3_snprintf()
+** returns a pointer to its buffer instead of the number of
+** characters actually written into the buffer. {END} We admit that
+** the number of characters written would be a more useful return
+** value but we cannot change the implementation of sqlite3_snprintf()
+** now without breaking compatibility.
+**
+** {F17406} As long as the buffer size is greater than zero, sqlite3_snprintf()
+** guarantees that the buffer is always zero-terminated. {F17407} The first
+** parameter "n" is the total size of the buffer, including space for
+** the zero terminator. {END} So the longest string that can be completely
+** written will be n-1 characters.
+**
+** These routines all implement some additional formatting
+** options that are useful for constructing SQL statements.
+** All of the usual printf formatting options apply. In addition, there
+** is are "%q", "%Q", and "%z" options.
+**
+** {F17410} The %q option works like %s in that it substitutes a null-terminated
+** string from the argument list. But %q also doubles every '\'' character.
+** %q is designed for use inside a string literal. {END} By doubling each '\''
+** character it escapes that character and allows it to be inserted into
+** the string.
+**
+** For example, so some string variable contains text as follows:
+**
+** <blockquote><pre>
+** char *zText = "It's a happy day!";
+** </pre></blockquote>
+**
+** One can use this text in an SQL statement as follows:
+**
+** <blockquote><pre>
+** char *zSQL = sqlite3_mprintf("INSERT INTO table VALUES('%q')", zText);
+** sqlite3_exec(db, zSQL, 0, 0, 0);
+** sqlite3_free(zSQL);
+** </pre></blockquote>
+**
+** Because the %q format string is used, the '\'' character in zText
+** is escaped and the SQL generated is as follows:
+**
+** <blockquote><pre>
+** INSERT INTO table1 VALUES('It''s a happy day!')
+** </pre></blockquote>
+**
+** This is correct. Had we used %s instead of %q, the generated SQL
+** would have looked like this:
+**
+** <blockquote><pre>
+** INSERT INTO table1 VALUES('It's a happy day!');
+** </pre></blockquote>
+**
+** This second example is an SQL syntax error. As a general rule you
+** should always use %q instead of %s when inserting text into a string
+** literal.
+**
+** {F17411} The %Q option works like %q except it also adds single quotes around
+** the outside of the total string. Or if the parameter in the argument
+** list is a NULL pointer, %Q substitutes the text "NULL" (without single
+** quotes) in place of the %Q option. {END} So, for example, one could say:
+**
+** <blockquote><pre>
+** char *zSQL = sqlite3_mprintf("INSERT INTO table VALUES(%Q)", zText);
+** sqlite3_exec(db, zSQL, 0, 0, 0);
+** sqlite3_free(zSQL);
+** </pre></blockquote>
+**
+** The code above will render a correct SQL statement in the zSQL
+** variable even if the zText variable is a NULL pointer.
+**
+** {F17412} The "%z" formatting option works exactly like "%s" with the
+** addition that after the string has been read and copied into

+** the legacy interfaces [sqlite3_prepare()] or [sqlite3_prepare16()],
+** then this function must be called one or more times to evaluate the
+** statement.
+**
+** The details of the behavior of this sqlite3_step() interface depend
+** on whether the statement was prepared using the newer "v2" interface
+** [sqlite3_prepare_v2()] and [sqlite3_prepare16_v2()] or the older legacy
+** interface [sqlite3_prepare()] and [sqlite3_prepare16()]. The use of the
+** new "v2" interface is recommended for new applications but the legacy
+** interface will continue to be supported.
+**
+** In the lagacy 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 [SQLITE_OK | result code]
+** or [SQLITE_IOERR_READ | extended result code] 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 a
+** 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 [sqlite3_column_int | 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 (example:
+** [SQLITE_INTERRUPT], [SQLITE_SCHEMA], [SQLITE_CORRUPT], and so forth)
+** can be obtained by calling [sqlite3_reset()] on the
+** [sqlite3_stmt | 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 [sqlite3_stmt | 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

+** and [SQLITE_MISUSE]. You must call [sqlite3_reset()] or
+** [sqlite3_finalize()] in order to find one of the specific
+** [SQLITE_ERROR | result 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 either [sqlite3_prepare_v2()] or [sqlite3_prepare16_v2()] instead
+** of the legacy [sqlite3_prepare()] and [sqlite3_prepare16()], then the

+** If the SQL statement is not currently point to a valid row, or if the
+** 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()] has been call subsequently.
+** If any of these routines are called after [sqlite3_reset()] or

+** 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 sqlite3_column_type() routine returns
+** [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 value
+** returned by sqlite3_column_type() is only meaningful if no type
+** conversions have occurred as described below. After a type conversion,
+** the value returned by sqlite3_column_type() is undefined. Future
+** versions of SQLite may change the behavior of sqlite3_column_type()
+** following a type conversion.
+**
+** 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.
+** The value returned does not include the zero terminator at the end
+** of the string. For clarity: the value returned is the number of
+** bytes in the string, not the number of characters.
+**
+** Strings returned by sqlite3_column_text() and sqlite3_column_text16(),
+** even zero-length strings, are always zero terminated. The return
+** value from sqlite3_column_blob() for a zero-length blob is an arbitrary
+** pointer, possibly even a NULL pointer.
+**
+** The sqlite3_column_bytes16() routine is similar to sqlite3_column_bytes()
+** but leaves the result in UTF-16 instead of UTF-8.
+** The zero terminator is not included in this count.
+**
+** These routines attempt to convert the value where appropriate. For
+** example, if the internal representation is FLOAT and a text result
+** is requested, [sqlite3_snprintf()] is used internally to do the conversion
+** automatically. The following table details the conversions that
+** are applied:
+**
+** <blockquote>
+** <table border="1">
+** <tr><th> Internal<br>Type <th> Requested<br>Type <th> Conversion
+**
+** <tr><td> NULL <td> INTEGER <td> Result is 0
+** <tr><td> NULL <td> FLOAT <td> Result is 0.0
+** <tr><td> NULL <td> TEXT <td> Result is NULL pointer
+** <tr><td> NULL <td> BLOB <td> Result is NULL pointer
+** <tr><td> INTEGER <td> FLOAT <td> Convert from integer to float
+** <tr><td> INTEGER <td> TEXT <td> ASCII rendering of the integer
+** <tr><td> INTEGER <td> BLOB <td> Same as for INTEGER->TEXT
+** <tr><td> FLOAT <td> INTEGER <td> Convert from float to integer
+** <tr><td> FLOAT <td> TEXT <td> ASCII rendering of the float
+** <tr><td> FLOAT <td> BLOB <td> Same as FLOAT->TEXT
+** <tr><td> TEXT <td> INTEGER <td> Use atoi()
+** <tr><td> TEXT <td> FLOAT <td> Use atof()
+** <tr><td> TEXT <td> BLOB <td> No change
+** <tr><td> BLOB <td> INTEGER <td> Convert to TEXT then use atoi()
+** <tr><td> BLOB <td> FLOAT <td> Convert to TEXT then use atof()
+** <tr><td> BLOB <td> TEXT <td> Add a zero terminator if needed
+** </table>
+** </blockquote>
+**
+** The table above makes reference to standard C library functions atoi()
+** and atof(). SQLite does not really use these functions. It has its
+** on equavalent internal routines. The atoi() and atof() names are
+** used in the table for brevity and because they are familiar to most
+** C programmers.
+**
+** 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:
+**
+** <ul>
+** <li><p> 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.</p></li>
+**
+** <li><p> 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.</p></li>
+**
+** <li><p> 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.</p></li>
+** </ul>
+**
+** 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 points to will have been modified. Other kinds
+** of conversion are done in place when it is possible, but sometime it is
+** not possible and in those cases prior pointers are invalidated.
+**
+** The safest and easiest to remember policy is to invoke these routines
+** in one of the following ways:
+**
+** <ul>
+** <li>sqlite3_column_text() followed by sqlite3_column_bytes()</li>
+** <li>sqlite3_column_blob() followed by sqlite3_column_bytes()</li>
+** <li>sqlite3_column_text16() followed by sqlite3_column_bytes16()</li>
+** </ul>
+**
+** 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 call 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 <b>not</b> pass the pointers returned
+** [sqlite3_column_blob()], [sqlite3_column_text()], etc. into
+** [sqlite3_free()].
+**
+** If a memory allocation error occurs during the evaluation of any
+** of these routines, a default value is returned. The default value
+** is either the integer 0, the floating point number 0.0, or a NULL
+** pointer. Subsequent calls to [sqlite3_errcode()] will return

+** sqlite3_create_function() and UTF-16 for sqlite3_create_function16().
+**
+** The first argument is the [sqlite3 | database handle] that holds the
+** SQL function or aggregate is to be added or redefined. If a single
+** program uses more than one database handle internally, then SQL
+** functions or aggregates must be added individually to each database
+** handle with which they will be used.
+**
+** 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, exclusive of the
+** zero-terminator. Note that the name length limit is in bytes, not
+** characters. Any attempt to create a function with a longer name
+** will result in an SQLITE_ERROR error.
+**
+** The third parameter is the number of arguments that the SQL function or
+** aggregate takes. If this parameter is negative, then the SQL function or
+** aggregate may take any number of arguments.
+**
+** The fourth parameter, eTextRep, specifies what
+** [SQLITE_UTF8 | text encoding] this SQL function prefers for
+** its parameters. Any SQL function implementation should be able to work
+** work with UTF-8, UTF-16le, or UTF-16be. But some implementations may be
+** more efficient with one encoding than another. It is allowed to
+** invoke sqlite3_create_function() or sqlite3_create_function16() multiple
+** times with the same function but with different values of eTextRep.
+** When multiple implementations of the same function are available, SQLite
+** will pick the one that involves the least amount of data conversion.
+** If there is only a single implementation which does not care what
+** text encoding is used, then the fourth argument should be
+** [SQLITE_ANY].
+**
+** The fifth parameter is an arbitrary pointer. The implementation
+** of the function can gain access to this pointer using
+** [sqlite3_user_data()].
+**
+** The seventh, eighth and ninth parameters, xFunc, xStep and xFinal, are

+** the xFunc callback only, NULL pointers should be passed as the xStep
+** and xFinal parameters. An aggregate SQL function requires an implementation

+** CAPI3REF: Obtaining SQL Function Parameter Values {F15100}
+**
+** The C-language implementation of SQL functions and aggregates uses
+** this set of interface routines to access the parameter values on
+** the function or aggregate.
+**
+** The xFunc (for scalar functions) or xStep (for aggregates) parameters
+** to [sqlite3_create_function()] and [sqlite3_create_function16()]
+** define callbacks that implement the SQL functions and aggregates.
+** The 4th parameter to these callbacks is an array of pointers to
+** [sqlite3_value] objects. There is one [sqlite3_value] object for
+** each parameter to the SQL function. These routines are used to
+** extract values from the [sqlite3_value] objects.
+**
+** These routines work just like the corresponding
+** [sqlite3_column_blob | sqlite3_column_* routines] except that
+** these routines take a single [sqlite3_value*] pointer instead
+** of an [sqlite3_stmt*] pointer and an integer column number.
+**
+** The sqlite3_value_text16() interface extracts a UTF16 string
+** in the native byte-order of the host machine. The
+** sqlite3_value_text16be() and sqlite3_value_text16le() interfaces
+** extract UTF16 strings as big-endian and little-endian respectively.
+**
+** 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 done. Otherwise no conversion occurs. The
+** [SQLITE_INTEGER | datatype] after conversion is returned.
+**
+** Please pay particular attention to the fact that the pointer that
+** is 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.
+** Or, if the sqlite3_value* argument comes from the [sqlite3_column_value()]
+** interface, then these routines should be called from the same thread

+** CAPI3REF: Mutexes {F17000}
+**
+** 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:
+**
+** <ul>
+** <li> SQLITE_MUTEX_OS2
+** <li> SQLITE_MUTEX_PTHREAD
+** <li> SQLITE_MUTEX_W32
+** <li> SQLITE_MUTEX_NOOP
+** </ul>
+**
+** 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_OS2,
+** SQLITE_MUTEX_PTHREAD, and SQLITE_MUTEX_W32 implementations
+** are appropriate for use on os/2, 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. The
+** mutex interface routines defined here become external
+** references in the SQLite library for which implementations
+** must be provided by the application. This facility allows an
+** application that links against SQLite to provide its own mutex
+** implementation without having to modify the SQLite core.
+**
+** {F17011} The sqlite3_mutex_alloc() routine allocates a new
+** mutex and returns a pointer to it. {F17012} If it returns NULL
+** that means that a mutex could not be allocated. {F17013} SQLite
+** will unwind its stack and return an error. {F17014} The argument
+** to sqlite3_mutex_alloc() is one of these integer constants:
+**
+** <ul>
+** <li> SQLITE_MUTEX_FAST
+** <li> SQLITE_MUTEX_RECURSIVE
+** <li> SQLITE_MUTEX_STATIC_MASTER
+** <li> SQLITE_MUTEX_STATIC_MEM
+** <li> SQLITE_MUTEX_STATIC_MEM2
+** <li> SQLITE_MUTEX_STATIC_PRNG
+** <li> SQLITE_MUTEX_STATIC_LRU
+** </ul> {END}
+**
+** {F17015} 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. {END}
+** The mutex implementation does not need to make a distinction
+** between SQLITE_MUTEX_RECURSIVE and SQLITE_MUTEX_FAST if it does
+** not want to. {F17016} But SQLite will only request a recursive mutex in
+** cases where it really needs one. {END} 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.
+**
+** {F17017} The other allowed parameters to sqlite3_mutex_alloc() each return
+** a pointer to a static preexisting mutex. {END} Four 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.
+**
+** {F17018} 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. {F17034} But for the static
+** mutex types, the same mutex is returned on every call that has
+** the same type number. {END}
+**
+** {F17019} The sqlite3_mutex_free() routine deallocates a previously
+** allocated dynamic mutex. {F17020} SQLite is careful to deallocate every
+** dynamic mutex that it allocates. {U17021} The dynamic mutexes must not be in
+** use when they are deallocated. {U17022} Attempting to deallocate a static
+** mutex results in undefined behavior. {F17023} SQLite never deallocates
+** a static mutex. {END}
+**
+** The sqlite3_mutex_enter() and sqlite3_mutex_try() routines attempt
+** to enter a mutex. {F17024} If another thread is already within the mutex,
+** sqlite3_mutex_enter() will block and sqlite3_mutex_try() will return
+** SQLITE_BUSY. {F17025} The sqlite3_mutex_try() interface returns SQLITE_OK
+** upon successful entry. {F17026} Mutexes created using
+** SQLITE_MUTEX_RECURSIVE can be entered multiple times by the same thread.
+** {F17027} In such cases the,
+** mutex must be exited an equal number of times before another thread
+** can enter. {U17028} If the same thread tries to enter any other
+** kind of mutex more than once, the behavior is undefined.
+** {F17029} SQLite will never exhibit
+** such behavior in its own use of mutexes. {END}
+**
+** Some systems (ex: windows95) do not the operation implemented by
+** sqlite3_mutex_try(). On those systems, sqlite3_mutex_try() will
+** always return SQLITE_BUSY. {F17030} The SQLite core only ever uses
+** sqlite3_mutex_try() as an optimization so this is acceptable behavior. {END}
+**
+** {F17031} The sqlite3_mutex_leave() routine exits a mutex that was
+** previously entered by the same thread. {U17032} The behavior
+** is undefined if the mutex is not currently entered by the
+** calling thread or is not currently allocated. {F17033} SQLite will
+** never do either. {END}
