+** This object defines the methods used to perform various operations
+** against the open file represented by the [sqlite3_file] object.
+**
+** If the 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 xOpen reported that it failed. The
+** only way to prevent a call to xClose following a failed xOpen
+** is for the 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

+** <li> [SQLITE_LOCK_NONE],
+** <li> [SQLITE_LOCK_SHARED],
+** <li> [SQLITE_LOCK_RESERVED],
+** <li> [SQLITE_LOCK_PENDING], or
+** <li> [SQLITE_LOCK_EXCLUSIVE].
+** </ul>
+** 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 [SQLITE_FCNTL_LOCKSTATE | list of opcodes] less than 100 is available.
+** Applications that define a custom xFileControl method should use opcodes
+** greater than 100 to avoid conflicts.
+**
+** 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:

+** <li> [SQLITE_IOCAP_SAFE_APPEND]
+** <li> [SQLITE_IOCAP_SEQUENTIAL]
+** </ul>
+**
+** The SQLITE_IOCAP_ATOMIC property means that all writes of

+**
+** 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".
+**
+** The value of the iVersion field is initially 1 but may be larger in
+** future versions of SQLite. Additional fields may be appended to this
+** object when the iVersion value is increased. Note that the structure
+** of the sqlite3_vfs object changes in the transaction between
+** SQLite version 3.5.9 and 3.6.0 and yet the iVersion field was not
+** modified.
+**
+** 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.
+**
+** SQLite will guarantee that the zFilename parameter to xOpen
+** is either a NULL pointer or string obtained
+** from xFullPathname(). 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 is 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:
+**
+** <ul>
+** <li> [SQLITE_OPEN_MAIN_DB]
+** <li> [SQLITE_OPEN_MAIN_JOURNAL]
+** <li> [SQLITE_OPEN_TEMP_DB]
+** <li> [SQLITE_OPEN_TEMP_JOURNAL]
+** <li> [SQLITE_OPEN_TRANSIENT_DB]
+** <li> [SQLITE_OPEN_SUBJOURNAL]
+** <li> [SQLITE_OPEN_MASTER_JOURNAL]
+** </ul>
+**
+** 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:
+**
+** <ul>
+** <li> [SQLITE_OPEN_DELETEONCLOSE]
+** <li> [SQLITE_OPEN_EXCLUSIVE]
+** </ul>
+**
+** 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, journals and for 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 <i>not</i> 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.
+**
+** 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 file can be a
+** directory.
+**
+** 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(), and xCurrentTime() 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()

+**
+** Among other things, sqlite3_initialize() shall invoke
+** sqlite3_os_init(). Similarly, sqlite3_shutdown()
+** shall invoke sqlite3_os_end().
+**
+** The sqlite3_initialize() routine returns [SQLITE_OK] on success.
+** If for some reason, sqlite3_initialize() is unable to initialize

+**
+** The sqlite3_initialize() routine is called internally by many other

+** 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

+**
+** The sqlite3_os_init() routine does operating-system specific

+**
+** An instance of this object defines the interface between SQLite
+** and low-level memory allocation routines.
+**
+** This object is used in only one place in the SQLite interface.
+** A pointer to an instance of this object is the argument to
+** [sqlite3_config()] when the configuration option is
+** [SQLITE_CONFIG_MALLOC] or [SQLITE_CONFIG_GETMALLOC].
+** 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 and xFree methods must work like the
+** malloc() and free() functions from the standard C library.
+** The xRealloc method must work like realloc() from the standard C library
+** with the exception that if the second argument to xRealloc is zero,
+** xRealloc must be a no-op - it must not perform any allocation or
+** deallocation. SQLite guaranteeds that the second argument to
+** xRealloc is always a value returned by a prior call to xRoundup.
+** And so in cases where xRoundup always returns a positive number,
+** xRealloc can perform exactly as the standard library realloc() and
+** still be in compliance with this specification.
+**
+** 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.

+** If the busy callback is NULL, then [SQLITE_BUSY] or [SQLITE_IOERR_BLOCKED]
+** is returned immediately upon encountering the lock. If the busy callback
+** is not NULL, then the callback will be invoked with two arguments.
+**
+** The first argument to the handler is a copy of the void* pointer which
+** is the third argument to sqlite3_busy_handler(). The second argument to
+** the handler callback is the number of times that the busy handler has
+** been invoked for this locking event. If the
+** busy callback returns 0, then no additional attempts are made to
+** access the database and [SQLITE_BUSY] or [SQLITE_IOERR_BLOCKED] is returned.
+** If the callback returns non-zero, then another attempt
+** is made to open the database for reading and the cycle repeats.
+**
+** The presence of a busy handler does not guarantee that it will be invoked
+** when there is lock contention. If SQLite determines that invoking the busy
+** handler could result in a deadlock, it will go ahead and return [SQLITE_BUSY]
+** or [SQLITE_IOERR_BLOCKED] instead of invoking the busy handler.
+** Consider a scenario where one process is holding a read lock that
+** it is trying to promote to a reserved lock and
+** a second process is holding a reserved lock that it is trying
+** to promote to an exclusive lock. The first process cannot proceed
+** because it is blocked by the second and the second process cannot
+** proceed because it is blocked by the first. If both processes
+** invoke the busy handlers, neither will make any progress. Therefore,
+** SQLite returns [SQLITE_BUSY] for the first process, hoping that this
+** will induce the first process to release its read lock and allow
+** the second process to proceed.
+**
+** The default busy callback is NULL.
+**
+** The [SQLITE_BUSY] error is converted to [SQLITE_IOERR_BLOCKED]
+** when SQLite is in the middle of a large transaction where all the
+** changes will not fit into the in-memory cache. SQLite will
+** 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. 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
+** the more severe [SQLITE_IOERR_BLOCKED]. This error code promotion
+** forces an automatic rollback of the changes. See the
+** <a href="/cvstrac/wiki?p=CorruptionFollowingBusyError">

+** 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:
+**
+** <blockquote><pre>
+** Name | Age
+** -----------------------
+** Alice | 43
+** Bob | 28
+** Cindy | 21
+** </pre></blockquote>
+**
+** There are two column (M==2) and three rows (N==3). Thus the
+** result table has 8 entries. Suppose the result table is stored
+** in an array names azResult. Then azResult holds this content:
+**
+** <blockquote><pre>
+** azResult&#91;0] = "Name";
+** azResult&#91;1] = "Age";
+** azResult&#91;2] = "Alice";
+** azResult&#91;3] = "43";
+** azResult&#91;4] = "Bob";
+** azResult&#91;5] = "28";
+** azResult&#91;6] = "Cindy";
+** azResult&#91;7] = "21";
+** </pre></blockquote>
+**
+** The sqlite3_get_table() function evaluates one or more
+** semicolon-separated SQL statements in the zero-terminated UTF-8
+** string of its 2nd parameter. It returns a result table to the
+** pointer given in its 3rd parameter.
+**
+** After the calling function has finished using the result, it should
+** pass the pointer to the result table 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
+** [sqlite3_exec()]. The sqlite3_get_table() routine does not have access
+** to any internal data structures of SQLite. It uses only the public
+** interface defined here. As a consequence, errors that occur in the
+** wrapper layer outside of the internal [sqlite3_exec()] call are not
+** reflected in subsequent calls to [sqlite3_errcode()] or [sqlite3_errmsg()].

+**
+** These routines are work-alikes of the "printf()" family of functions
+** from the standard C library.
+**
+** The sqlite3_mprintf() and sqlite3_vmprintf() routines write their
+** results into memory obtained from [sqlite3_malloc()].
+** The strings returned by these two routines should be
+** released by [sqlite3_free()]. Both routines return a
+** NULL pointer if [sqlite3_malloc()] is unable to allocate enough
+** memory to hold the resulting string.
+**
+** 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. 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. Note also that sqlite3_snprintf()
+** returns a pointer to its buffer instead of the number of
+** characters actually written into the buffer. 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.
+**
+** As long as the buffer size is greater than zero, sqlite3_snprintf()
+** guarantees that the buffer is always zero-terminated. The first
+** parameter "n" is the total size of the buffer, including space for
+** the zero terminator. 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.
+**
+** 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. By doubling each '\''
+** character it escapes that character and allows it to be inserted into
+** the string.
+**
+** For example, assume the string variable zText 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.
+**
+** The %Q option works like %q except it also adds single quotes around
+** the outside of the total string. Additionally, 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. 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.
+**
+** 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}

+** CAPI3REF: Memory Allocation Subsystem {H17300} <S20000>
+**
+** 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.
+**
+** 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() interface attempts to resize a
+** prior memory allocation to be at least N bytes, where N is the
+** second parameter. The memory allocation to be resized is the first
+** parameter. If the first parameter to sqlite3_realloc()
+** is a NULL pointer then its behavior is identical to calling
+** sqlite3_malloc(N) where N is the second parameter to sqlite3_realloc().
+** If the second parameter to sqlite3_realloc() is zero or
+** negative then the behavior is exactly the same as calling
+** sqlite3_free(P) where P is the first parameter to sqlite3_realloc().
+** sqlite3_realloc() returns a pointer to a memory allocation
+** of at least N bytes in size or NULL if sufficient memory is unavailable.
+** 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() and the prior allocation is freed.
+** If sqlite3_realloc() returns NULL, then the prior allocation
+** is not freed.
+**
+** The memory returned by sqlite3_malloc() and sqlite3_realloc()
+** is always aligned to at least an 8 byte boundary. {END}
+**
+** The default implementation of the memory allocation subsystem uses
+** the malloc(), realloc() and free() provided by the standard C library.
+** {H17382} However, if SQLite is compiled with the
+** SQLITE_MEMORY_SIZE=<i>NNN</i> C preprocessor macro (where <i>NNN</i>
+** is an integer), then SQLite create a static array of at least

+**
+** This routine registers a 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_prepare16()] and [sqlite3_prepare16_v2()]. 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 zero-terminated strings that contain additional
+** details about the action to be authorized.
+**
+** 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.
+** 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.
+**
+** The authorizer callback must not do anything that will modify
+** the database connection that invoked the authorizer callback.
+** Note that [sqlite3_prepare_v2()] and [sqlite3_step()] both modify their
+** database connections for the meaning of "modify" in this paragraph.
+**
+** When [sqlite3_prepare_v2()] is used to prepare a statement, the
+** 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()].

+** CAPI3REF: Compiling An SQL Statement {H13010} <S10000>
+** KEYWORDS: {SQL statement compiler}
+**
+** To execute an SQL query, it must first be compiled into a byte-code
+** program using one of these routines.
+**
+** 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() and sqlite3_prepare_v2()
+** interfaces use UTF-8, and sqlite3_prepare16() and sqlite3_prepare16_v2()
+** use UTF-16.
+**
+** If the nByte argument is less than zero, then zSql is read up to the
+** first zero terminator. If nByte is non-negative, then it is the maximum
+** number of bytes read from zSql. When nByte is non-negative, the
+** zSql string ends at either the first '\000' or '\u0000' character or
+** the nByte-th byte, whichever comes first. If the caller knows
+** that the supplied string is nul-terminated, then there is a small
+** performance advantage to be gained by passing an nByte parameter that
+** is equal to the number of bytes in the input string <i>including</i>
+** the nul-terminator bytes.
+**
+** 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, [SQLITE_OK] is returned, otherwise an [error code] is returned.
+**
+** The sqlite3_prepare_v2() and sqlite3_prepare16_v2() interfaces are
+** recommended for all new programs. The two older interfaces are retained
+** for backwards compatibility, but their use is discouraged.
+** In the "v2" 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 a differently in two ways:
+**
+** <ol>
+** <li>
+** 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. If the schema has changed in
+** a way that makes the statement no longer valid, [sqlite3_step()] will still
+** return [SQLITE_SCHEMA]. But unlike the legacy behavior, [SQLITE_SCHEMA] is
+** now a fatal error. Calling [sqlite3_prepare_v2()] again will not make the
+** error go away. Note: use [sqlite3_errmsg()] to find the text
+** of the parsing error that results in an [SQLITE_SCHEMA] return.
+** </li>
+**
+** <li>
+** 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 you 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.

+** The terms "protected" and "unprotected" refer to whether or not

+** <li> @VVV
+** <li> $VVV
+** </ul>
+**
+** In the templates above, NNN represents an integer literal,
+** and VVV represents an alphanumeric identifer. The values of these
+** parameters (also called "host parameter names" or "SQL parameters")
+** can be set using the sqlite3_bind_*() routines defined here.
+**
+** The first argument to the sqlite3_bind_*() routines is always
+** a pointer to the [sqlite3_stmt] object returned from
+** [sqlite3_prepare_v2()] or its variants.
+**
+** The second argument is the index of the SQL parameter to be set.
+** The leftmost SQL parameter has an index of 1. When the same named
+** SQL parameter is used more than once, second and subsequent
+** occurrences have the same index as the first occurrence.
+** The index for named parameters can be looked up using the
+** [sqlite3_bind_parameter_index()] API if desired. The index
+** for "?NNN" parameters is the value of NNN.
+** The NNN value must be between 1 and the [sqlite3_limit()]
+** parameter [SQLITE_LIMIT_VARIABLE_NUMBER] (default value: 999).
+**
+** The third argument is the value to bind to the parameter.
+**
+** In those routines that have a fourth argument, its value is the
+** number of bytes in the parameter. To be clear: the value is the
+** number of <u>bytes</u> in the value, not the number of characters.
+** If the fourth parameter is negative, the length of the string is
+** the number of bytes up to the first zero terminator.
+**
+** The fifth argument to sqlite3_bind_blob(), sqlite3_bind_text(), and
+** sqlite3_bind_text16() is a destructor used to dispose of the BLOB or
+** string after SQLite has finished with it. If the fifth argument is
+** the special value [SQLITE_STATIC], then SQLite assumes that the
+** information is in static, unmanaged space and does not need to be freed.
+** If the fifth argument has the value [SQLITE_TRANSIENT], then
+** SQLite makes its own private copy of the data immediately, before
+** the sqlite3_bind_*() routine returns.
+**
+** The sqlite3_bind_zeroblob() routine binds a BLOB of length N that
+** is filled with zeroes. A zeroblob uses a fixed amount of memory
+** (just an integer to hold its size) while it is being processed.
+** Zeroblobs are intended to serve as placeholders for BLOBs whose
+** content is later written using
+** [sqlite3_blob_open | incremental BLOB I/O] routines.
+** A negative value for the zeroblob results in a zero-length BLOB.
+**
+** The sqlite3_bind_*() routines must be called after
+** [sqlite3_prepare_v2()] (and its variants) or [sqlite3_reset()] and
+** before [sqlite3_step()].
+** Bindings are not cleared by the [sqlite3_reset()] routine.
+** Unbound parameters are interpreted as NULL.

+** These routines return [SQLITE_OK] on success or an error code if
+** anything goes wrong. [SQLITE_RANGE] is returned if the parameter

+** [SQLITE_MISUSE] might be returned if these routines are called on a

+** Detection of misuse is unreliable. Applications should not depend

+**
+** The details of the behavior of the sqlite3_step() interface depend

+** [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 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 [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

+** [sqlite3_reset()] or [sqlite3_finalize()] in order to find one of the
+** specific [error codes] that better describes the error.

+** These routines form the "result set query" interface.
+**
+** 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.
+**
+** 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 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 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 empty 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 in native byte order instead of UTF-8.
+** The zero terminator is not included in this count.
+**
+** The object returned by [sqlite3_column_value()] is an
+** [unprotected sqlite3_value] object. An unprotected sqlite3_value object
+** may only be used 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()], then the behavior is undefined.
+**
+** 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 perform 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 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
+** own equivalent 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> 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.</li>
+** <li> 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.</li>
+** <li> 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.</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 sometimes they
+** are 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 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 <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

+** for sqlite3_create_function16().
+**
+** The first parameter is the [database connection] to which the SQL

+** 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
+** 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 should be passed as the xStep and xFinal
+** parameters. An aggregate SQL function requires an implementation of xStep
+** and xFinal and NULL should be passed for xFunc. To delete an existing
+** SQL function or aggregate, pass NULL for all three function callbacks.
+**
+** 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

+**
+** Built-in functions may be overloaded by new application-defined functions.
+** The first application-defined function with a given name overrides all
+** built-in functions in the same [database connection] with the same name.
+** Subsequent application-defined functions of the same name only override
+** prior application-defined functions that are an exact match for the

+** CAPI3REF: Obtaining SQL Function Parameter Values {H15100} <S20200>
+**
+** 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
+** [protected 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 only with [protected sqlite3_value] objects.
+** Any attempt to use these routines on an [unprotected sqlite3_value]
+** object results in undefined behavior.
+**
+** 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.
+**
+** 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.
+**
+** Please pay particular attention to the fact that the pointer returned
+** from [sqlite3_value_blob()], [sqlite3_value_text()], or

+** 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() interfaces 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.
+**
+** 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 in native
+** byte order. 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_toobig() interface causes SQLite to throw an error
+** indicating that a string or BLOB is to long to represent.
+**
+** The sqlite3_result_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.
+** 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 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
+** from [sqlite3_malloc()] before it returns.
+**
+** The sqlite3_result_value() interface sets the result of
+** the application-defined function to be a copy the
+** [unprotected sqlite3_value] object specified by the 2nd parameter. The

+**
+** <pre>column OP expr</pre>
+**
+** where OP is =, &lt;, &lt;=, &gt;, or &gt;=. The particular operator is
+** stored in aConstraint[].op. 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 in the correct
+** form that refer 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 [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

+** is true, then the constraint is assumed to be fully handled by the
+** virtual table and is not checked again by SQLite.
+**
+** The idxNum and idxPtr values are recorded and passed into the

+** The SQLite core uses these routines for thread

+** 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. 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().
+**
+** {H17011} The sqlite3_mutex_alloc() routine allocates a new
+** mutex and returns a pointer to it. {H17012} If it returns NULL
+** that means that a mutex could not be allocated. {H17013} SQLite
+** will unwind its stack and return an error. {H17014} The argument
+** to sqlite3_mutex_alloc() is one of these integer constants:
+**
+** <ul>

+** <li> SQLITE_MUTEX_STATIC_LRU
+** <li> SQLITE_MUTEX_STATIC_LRU2
+** </ul>
+**
+** {H17015} 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. {H17016} 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.

+** may add additional static mutexes. Static mutexes are for internal

+** SQLITE_MUTEX_RECURSIVE.
+**
+** {H17018} 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. {H17034} But for the static
+** mutex types, the same mutex is returned on every call that has

+**
+** {H17019} The sqlite3_mutex_free() routine deallocates a previously

+** use when they are deallocated. {A17022} Attempting to deallocate a static
+** mutex results in undefined behavior. {H17023} SQLite never deallocates
+** a static mutex. {END}
+**
+** The sqlite3_mutex_enter() and sqlite3_mutex_try() routines attempt
+** to enter a mutex. {H17024} If another thread is already within the mutex,
+** sqlite3_mutex_enter() will block and sqlite3_mutex_try() will return
+** SQLITE_BUSY. {H17025} The sqlite3_mutex_try() interface returns [SQLITE_OK]

+**
+** The only difference is that the public sqlite3_XXX functions enumerated

+** The xMutexInit() method must be threadsafe. It must be harmless to

+**
+** SQLite will invoke the xMutexEnd() method when [sqlite3_shutdown()] is

+** KEYWORDS: {page cache}
+** EXPERIMENTAL
+**
+** The [sqlite3_config]([SQLITE_CONFIG_PCACHE], ...) interface can
+** register an alternative page cache implementation by passing in an
+** instance of the sqlite3_pcache_methods structure. The majority of the
+** heap memory used by SQLite is used by the page cache to cache data read
+** from, or ready to be written to, the database file. By implementing a
+** custom page cache using this API, an application can control more
+** precisely the amount of memory consumed by SQLite, the way in which
+** that memory is allocated and released, and the policies used to
+** determine exactly which parts of a database file are cached and for
+** how long.
+**
+** The contents of the sqlite3_pcache_methods structure are copied to an
+** internal buffer by SQLite within the call to [sqlite3_config]. Hence
+** the application may discard the parameter after the call to
+** [sqlite3_config()] returns.
+**
+** The xInit() method is called once for each call to [sqlite3_initialize()]
+** (usually only once during the lifetime of the process). It is passed
+** a copy of the sqlite3_pcache_methods.pArg value. It can be used to set
+** up global structures and mutexes required by the custom page cache
+** implementation.
+**
+** The xShutdown() method is called from within [sqlite3_shutdown()],
+** if the application invokes this API. It can be used to clean up
+** any outstanding resources before process shutdown, if required.
+**
+** SQLite holds a [SQLITE_MUTEX_RECURSIVE] mutex when it invokes
+** 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() method is used 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 not be a power of two. szPage
+** will the page size of the database file that is to be cached plus an
+** increment (here called "R") of about 100 or 200. SQLite will use the
+** extra R bytes on each page to store metadata about the underlying
+** database page on disk. The value of R depends
+** on the SQLite version, the target platform, and how SQLite was compiled.
+** R is constant for a particular build of SQLite. The second 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, a cache created with bPurgeable set to false will
+** never contain any unpinned pages.
+**
+** 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() method should return the number of pages currently
+** stored in the cache.
+**
+** The xFetch() method is used to fetch a page and return a pointer to it.
+** A 'page', in this context, is a buffer of szPage bytes aligned at an
+** 8-byte boundary. The page to be fetched is determined by the key. The
+** mimimum 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
+** behavior of the cache implementation is determined by the value of the
+** createFlag parameter passed to xFetch, according to the following table:
+**
+** <table border=1 width=85% align=center>
+** <tr><th> createFlag <th> Behaviour when page is not already in cache
+** <tr><td> 0 <td> Do not allocate a new page. Return NULL.
+** <tr><td> 1 <td> Allocate a new page if it easy and convenient to do so.
+** Otherwise return NULL.
+** <tr><td> 2 <td> Make every effort to allocate a new page. Only return
+** NULL if allocating a new page is effectively impossible.
+** </table>
+**
+** SQLite will normally invoke xFetch() with a createFlag of 0 or 1. If
+** a call to xFetch() with createFlag==1 returns NULL, then SQLite will
+** attempt to unpin one or more cache pages by spilling the content of
+** pinned pages to disk and synching the operating system disk cache. After
+** attempting to unpin pages, the xFetch() method will be invoked again with
+** a createFlag of 2.
+**
+** 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 should be evicted from the cache. In this case SQLite
+** assumes that the next time the page is retrieved from the cache using
+** the xFetch() method, it will be zeroed. If the discard parameter is
+** zero, then the page is considered to be unpinned. The cache implementation
+** may choose to evict unpinned pages at any time.
+**
+** The cache is not required to perform any reference counting. A single
+** call to xUnpin() unpins the page regardless of the number of prior calls
+** to xFetch().
+**
+** The xRekey() method is used to change the key value associated with the
+** page passed as the second argument from oldKey to newKey. If the cache
+** previously contains an entry associated with newKey, it should 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() 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_methods
+** functions.

+** read-locked while it is actually being read, it is not locked
+** continuously for the entire operation. Thus, the backup may be
+** performed on a live database without preventing other users from
+** writing to the database for an extended period of time.
+**
+** To perform a backup operation:
+** <ol>
+** <li><b>sqlite3_backup_init()</b> is called once to initialize the
+** backup,
+** <li><b>sqlite3_backup_step()</b> is called one or more times to transfer
+** the data between the two databases, and finally
+** <li><b>sqlite3_backup_finish()</b> is called to release all resources
+** associated with the backup operation.
+** </ol>
+** There should be exactly one call to sqlite3_backup_finish() for each
+** successful call to sqlite3_backup_init().
+**
+** <b>sqlite3_backup_init()</b>
+**
+** The first two arguments passed to [sqlite3_backup_init()] are the database
+** handle associated with the destination database and the database name
+** used to attach the destination database to the handle. The database name
+** is "main" for the main database, "temp" for the temporary database, or
+** the name specified as part of the [ATTACH] statement if the destination is
+** an attached database. The third and fourth arguments passed to
+** sqlite3_backup_init() identify the [database connection]
+** and database name used
+** to access the source database. The values passed for the source and
+** destination [database connection] parameters must not be the same.
+**
+** If an error occurs within sqlite3_backup_init(), then NULL is returned
+** and an error code and error message written into the [database connection]
+** passed as the first argument. They may be retrieved using the
+** [sqlite3_errcode()], [sqlite3_errmsg()], and [sqlite3_errmsg16()] functions.
+** Otherwise, if successful, a pointer to an [sqlite3_backup] object is
+** returned. This pointer may be used with the sqlite3_backup_step() and
+** sqlite3_backup_finish() functions to perform the specified backup
+** operation.
+**
+** <b>sqlite3_backup_step()</b>
+**
+** Function [sqlite3_backup_step()] is used to copy up to nPage pages between
+** the source and destination databases, where nPage is the value of the
+** second parameter passed to sqlite3_backup_step(). If nPage is a negative
+** value, all remaining source pages are copied. If the required pages are
+** succesfully copied, but there are still more pages to copy before the
+** backup is complete, it returns [SQLITE_OK]. If no error occured and there
+** are no more pages to copy, then [SQLITE_DONE] is returned. If an error
+** occurs, then an SQLite error code is returned. As well as [SQLITE_OK] and
+** [SQLITE_DONE], a call to sqlite3_backup_step() may return [SQLITE_READONLY],
+** [SQLITE_NOMEM], [SQLITE_BUSY], [SQLITE_LOCKED], or an
+** [SQLITE_IOERR_ACCESS | SQLITE_IOERR_XXX] extended error code.
+**
+** As well as the case where the destination database file was opened for
+** read-only access, sqlite3_backup_step() may return [SQLITE_READONLY] if
+** the destination is an in-memory database with a different page size
+** from the source database.
+**
+** If sqlite3_backup_step() cannot obtain a required file-system lock, then
+** the [sqlite3_busy_handler | busy-handler function]
+** is invoked (if one is specified). If the
+** busy-handler returns non-zero before the lock is available, then
+** [SQLITE_BUSY] is returned to the caller. In this case the call to
+** sqlite3_backup_step() can be retried later. If the source
+** [database connection]
+** is being used to write to the source database when sqlite3_backup_step()
+** is called, then [SQLITE_LOCKED] is returned immediately. Again, in this
+** case the call to sqlite3_backup_step() can be retried later on. If
+** [SQLITE_IOERR_ACCESS | SQLITE_IOERR_XXX], [SQLITE_NOMEM], or
+** [SQLITE_READONLY] is returned, then
+** there is no point in retrying the call to sqlite3_backup_step(). These
+** errors are considered fatal. At this point the application must accept
+** that the backup operation has failed and pass the backup operation handle
+** to the sqlite3_backup_finish() to release associated resources.
+**
+** Following the first call to sqlite3_backup_step(), an exclusive lock is
+** obtained on the destination file. It is not released until either
+** sqlite3_backup_finish() is called or the backup operation is complete
+** and sqlite3_backup_step() returns [SQLITE_DONE]. Additionally, each time
+** a call to sqlite3_backup_step() is made a [shared lock] is obtained on
+** the source database file. This lock is released before the
+** sqlite3_backup_step() call returns. Because the source database is not
+** locked between calls to sqlite3_backup_step(), it may be modified mid-way
+** through the backup procedure. If the source database is modified by an
+** external process or via a database connection other than the one being
+** used by the backup operation, then the backup will be transparently
+** restarted by the next call to sqlite3_backup_step(). If the source
+** database is modified by the using the same database connection as is used
+** by the backup operation, then the backup database is transparently
+** updated at the same time.
+**
+** <b>sqlite3_backup_finish()</b>
+**
+** Once sqlite3_backup_step() has returned [SQLITE_DONE], or when the
+** application wishes to abandon the backup operation, the [sqlite3_backup]
+** object should be passed to sqlite3_backup_finish(). This releases all
+** resources associated with the backup operation. If sqlite3_backup_step()
+** has not yet returned [SQLITE_DONE], then any active write-transaction on the
+** destination database is rolled back. The [sqlite3_backup] object is invalid
+** and may not be used following a call to sqlite3_backup_finish().
+**
+** The value returned by sqlite3_backup_finish is [SQLITE_OK] if no error
+** occurred, regardless or whether or not sqlite3_backup_step() was called
+** a sufficient number of times to complete the backup operation. Or, if
+** an out-of-memory condition or IO error occured during a call to
+** sqlite3_backup_step() then [SQLITE_NOMEM] or an
+** [SQLITE_IOERR_ACCESS | SQLITE_IOERR_XXX] error code
+** is returned. In this case the error code and an error message are
+** written to the destination [database connection].
+**
+** A return of [SQLITE_BUSY] or [SQLITE_LOCKED] from sqlite3_backup_step() is
+** not a permanent error and does not affect the return value of
+** sqlite3_backup_finish().
+**
+** <b>sqlite3_backup_remaining(), sqlite3_backup_pagecount()</b>
+**
+** Each call to sqlite3_backup_step() sets two values stored internally
+** by an [sqlite3_backup] object. The number of pages still to be backed
+** up, which may be queried by sqlite3_backup_remaining(), and the total
+** number of pages in the source database file, which may be queried by
+** sqlite3_backup_pagecount().
+**
+** The values returned by these functions are only updated by
+** sqlite3_backup_step(). If the source database is modified during a backup
+** operation, then the values are not updated to account for any extra
+** pages that need to be updated or the size of the source database file
+** changing.
+**
+** <b>Concurrent Usage of Database Handles</b>
+**
+** The source [database connection] may be used by the application for other
+** purposes while a backup operation is underway or being initialized.
+** If SQLite is compiled and configured to support threadsafe database
+** connections, then the source database connection may be used concurrently
+** from within other threads.
+**
+** However, the application must guarantee that the destination database
+** connection handle is not passed to any other API (by any thread) after
+** sqlite3_backup_init() is called and before the corresponding call to
+** sqlite3_backup_finish(). Unfortunately SQLite does not currently check
+** for this, if the application does use the destination [database connection]
+** for some other purpose during a backup operation, things may appear to
+** work correctly but in fact be subtly malfunctioning. Use of the
+** destination database connection while a backup is in progress might
+** also cause a mutex deadlock.
+**
+** Furthermore, 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 file-system 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.

+** CAPI3REF: Unlock Notification
+** EXPERIMENTAL
+**
+** When running in shared-cache mode, a database operation may fail with
+** an [SQLITE_LOCKED] error if the required locks on the shared-cache or
+** 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 connections 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 cancelled. 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.
+**
+** <b>Callback Invocation Details</b>
+**
+** 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 connections 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.
+**
+** <b>Deadlock Detection</b>
+**
+** 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.
+**
+** <b>The "DROP TABLE" Exception</b>
+**
+** 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.
