** <dt>SQLITE_DBCONFIG_RESET_DATABASE</dt>
** <dd> Set the SQLITE_DBCONFIG_RESET_DATABASE flag and then run
** [VACUUM] in order to reset a database back to an empty database
** with no schema and no content. The following process works even for
** a badly corrupted database file:
** <ol>
** <li> If the database connection is newly opened, make sure it has read the
**      database schema by preparing then discarding some query against the
**      database, or calling sqlite3_table_column_metadata(), ignoring any
**      errors.  This step is only necessary if the application desires to keep
**      the database in WAL mode after the reset if it was in WAL mode before
**      the reset.  
** <li> sqlite3_db_config(db, SQLITE_DBCONFIG_RESET_DATABASE, 1, 0);
** <li> [sqlite3_exec](db, "[VACUUM]", 0, 0, 0);
** <li> sqlite3_db_config(db, SQLITE_DBCONFIG_RESET_DATABASE, 0, 0);
** </ol>
** Because resetting a database is destructive and irreversible, the
** process requires the use of this obscure API and multiple steps to help
** ensure that it does not happen by accident.

** CAPI3REF: Error Codes And Messages
** METHOD: sqlite3
**
** ^If the most recent sqlite3_* API call associated with 
** [database connection] D failed, then the sqlite3_errcode(D) interface
** returns the numeric [result code] or [extended result code] for that
** API call.


** ^The sqlite3_extended_errcode()
** interface is the same except that it always returns the 
** [extended result code] even when extended result codes are
** disabled.
**
** The values returned by sqlite3_errcode() and/or
** sqlite3_extended_errcode() might change with each API call.
** Except, there are some interfaces that are guaranteed to never
** change the value of the error code.  The error-code preserving
** interfaces are:
**
** <ul>
** <li> sqlite3_errcode()
** <li> sqlite3_extended_errcode()
** <li> sqlite3_errmsg()
** <li> sqlite3_errmsg16()
** </ul>
**
** ^The sqlite3_errmsg() and sqlite3_errmsg16() return English-language
** text that describes the error, as either UTF-8 or UTF-16 respectively.
** ^(Memory to hold the error message string is managed internally.
** The application does not need to worry about freeing the result.
** However, the error string might be overwritten or deallocated by
** subsequent calls to other SQLite interface functions.)^

** ^The pointers returned are valid until a type conversion occurs as
** described above, or until [sqlite3_step()] or [sqlite3_reset()] or
** [sqlite3_finalize()] is called.  ^The memory space used to hold strings
** and BLOBs is freed automatically.  Do not pass the pointers returned
** from [sqlite3_column_blob()], [sqlite3_column_text()], etc. into
** [sqlite3_free()].
**
** As long as the input parameters are correct, these routines will only
** fail if an out-of-memory error occurs during a format conversion.
** Only the following subset of interfaces are subject to out-of-memory
** errors:
**
** <ul>
** <li> sqlite3_column_blob()
** <li> sqlite3_column_text()
** <li> sqlite3_column_text16()
** <li> sqlite3_column_bytes()
** <li> sqlite3_column_bytes16()
** </ul>
**
** If an out-of-memory error occurs, then the return value from these
** routines is the same as if the column had contained an SQL NULL value.

** Valid SQL NULL returns can be distinguished from out-of-memory errors
** by invoking the [sqlite3_errcode()] immediately after the suspect
** return value is obtained and before any
** other SQLite interface is called on the same [database connection].

** KEYWORDS: {application-defined SQL functions}
** METHOD: sqlite3
**
** ^These functions (collectively known as "function creation routines")
** are used to add SQL functions or aggregates or to redefine the behavior
** of existing SQL functions or aggregates. The only differences between
** the three "sqlite3_create_function*" routines are the text encoding 
** expected for the second parameter (the name of the function being 
** created) and the presence or absence of a destructor callback for
** the application data pointer. Function sqlite3_create_window_function()
** is similar, but allows the user to supply the extra callback functions
** needed by [aggregate window functions].
**
** ^The first parameter is the [database connection] to which the SQL
** function is to be added.  ^If an application uses more than one database
** connection then application-defined SQL functions must be added
** to each database connection separately.
**
** ^The second parameter is the name of the SQL function to be created or

** function that is not deterministic.  The SQLite query planner is able to
** perform additional optimizations on deterministic functions, so use
** of the [SQLITE_DETERMINISTIC] flag is recommended where possible.
**
** ^(The fifth parameter is an arbitrary pointer.  The implementation of the
** function can gain access to this pointer using [sqlite3_user_data()].)^
**
** ^The sixth, seventh and eighth parameters passed to the three
** "sqlite3_create_function*" functions, xFunc, xStep and xFinal, are
** pointers to C-language functions that implement the SQL function or
** aggregate. ^A scalar SQL function requires an implementation of the xFunc
** callback only; NULL pointers must be passed as the xStep and xFinal
** parameters. ^An aggregate SQL function requires an implementation of xStep
** and xFinal and NULL pointer must be passed for xFunc. ^To delete an existing
** SQL function or aggregate, pass NULL pointers for all three function
** callbacks.
**
** ^The sixth, seventh, eighth and ninth parameters (xStep, xFinal, xValue 
** and xInverse) passed to sqlite3_create_window_function are pointers to
** C-lanugage callbacks that implement the new function. xStep and xFinal
** must both be non-NULL. xValue and xInverse may either both be NULL, in
** which case a regular aggregate function is created, or must both be 
** non-NULL, in which case the new function may be used as either an aggregate
** or aggregate window function. More details regarding the implementation
** of aggregate window functions are 
** [user-defined window functions|available here].
**
** ^(If the final parameter to sqlite3_create_function_v2() or
** sqlite3_create_window_function() is not NULL, then it is destructor for
** the application data pointer. The destructor is invoked when the function 
** is deleted, either by being overloaded or when the database connection 
** closes.)^ ^The destructor is also invoked if the call to 
** sqlite3_create_function_v2() fails.  ^When the destructor callback is

** invoked, it is passed a single argument which is a copy of the application
** data pointer which was the fifth parameter to sqlite3_create_function_v2().
**
** ^It is permitted to register multiple implementations of the same
** functions with the same name but with either differing numbers of
** arguments or differing preferred text encodings.  ^SQLite will use
** the implementation that most closely matches the way in which the
** SQL function is used.  ^A function implementation with a non-negative
** nArg parameter is a better match than a function implementation with
