 and subsequent
 occurrences have the same index as the first occurrence.  The index for

 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.  This is the number of characters for UTF-8 strings
 and the number of bytes for UTF-16 strings and blobs.  The number
 of bytes does not include the zero-terminator at the end of strings.
 If the fourth parameter is negative, the length of the string is
 computed using strlen().

 The fifth argument to sqlite3_bind_blob(), sqlite3_bind_text(), and
 sqlite3_bind_text16() is a destructor used to dispose of the BLOB or

 sqlite3_column_... routines except that these routines take a single
 sqlite3_value* pointer instead of an sqlite3_stmt* and an integer
 column number.

 See the documentation under sqlite3_column_blob for additional
 information.
}

api {} {
  int sqlite3_sleep(int);
} {
 Sleep for a little while. The second parameter is the number of
 miliseconds to sleep for. 

 If the operating system does not support sleep requests with 
 milisecond time resolution, then the time will be rounded up to 
 the nearest second. The number of miliseconds of sleep actually 
 requested from the operating system is returned.
}

api {} {
  int sqlite3_expired(sqlite3_stmt*);
} {
 Return TRUE (non-zero) of the statement supplied as an argument needs
 to be recompiled.  A statement needs to be recompiled whenever the
 execution environment changes in a way that would alter the program
 that sqlite3_prepare() generates.  For example, if new functions or
 collating sequences are registered or if an authorizer function is
 added or changed.
}

api {} {
  int sqlite3_transfer_bindings(sqlite3_stmt*, sqlite3_stmt*);
} {
 Move all bindings from the first prepared statement over to the second.
 This routine is useful, for example, if the first prepared statement
 fails with an SQLITE_SCHEMA error.  The same SQL can be prepared into
 the second prepared statement then all of the bindings transfered over
 to the second statement before the first statement is finalized.
}

api {} {
  int sqlite3_global_recover();
} {
 This function is called to recover from a malloc() failure that occured
 within the SQLite library. Normally, after a single malloc() fails the 
 library refuses to function (all major calls return SQLITE_NOMEM).
 This function restores the library state so that it can be used again.

 All existing statements (sqlite3_stmt pointers) must be finalized or
 reset before this call is made. Otherwise, SQLITE_BUSY is returned.
 If any in-memory databases are in use, either as a main or TEMP
 database, SQLITE_ERROR is returned. In either of these cases, the 
 library is not reset and remains unusable.

 This function is *not* threadsafe. Calling this from within a threaded
 application when threads other than the caller have used SQLite is
 dangerous and will almost certainly result in malfunctions.

 This functionality can be omitted from a build by defining the 
 SQLITE_OMIT_GLOBALRECOVER at compile time.
}

api {} {
  int sqlite3_get_autocommit(sqlite3*);
} {
 Test to see whether or not the database connection is in autocommit
 mode.  Return TRUE if it is and FALSE if not.  Autocommit mode is on
 by default.  Autocommit is disabled by a BEGIN statement and reenabled
 by the next COMMIT or ROLLBACK.
}

api {} {
  int sqlite3_clear_bindings(sqlite3_stmt*);
} {
 Set all the parameters in the compiled SQL statement back to NULL.
}

api {} {
  int sqlite3_db_handle(sqlite3_stmt*);
} {
 Return the sqlite3* database handle to which the prepared statement given
 in the argument belongs.  This is the same database handle that was
 the first argument to the sqlite3_prepare() that was used to create
 the statement in the first place.
