**
** The sqlite3_errcode() interface returns the numeric [result code] or
** [extended result code] for the most recent failed sqlite3_* API call
** associated with a [database connection]. If a prior API call failed
** but the most recent API call succeeded, the return value from
** sqlite3_errcode() is undefined.
** sqlite3_errcode() is undefined.  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 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.
**
** If an interface fails with SQLITE_MISUSE, that means the interface
** was invoked incorrectly by the application.  In that case, the
** error code and message may or may not be set.
**
** INVARIANTS:
**
** {H12801} The [sqlite3_errcode(D)] interface returns the numeric
**          [result code] or [extended result code] for the most recently
**          failed interface call associated with the [database connection] D.
**
** {H12802} The [sqlite3_extended_errcode(D)] interface returns the numeric
**          [extended result code] for the most recently
**          failed interface call associated with the [database connection] D.
**
** {H12803} The [sqlite3_errmsg(D)] and [sqlite3_errmsg16(D)]
**          interfaces return English-language text that describes
**          the error in the mostly recently failed interface call,
**          encoded as either UTF-8 or UTF-16 respectively.
**
** {H12807} The strings returned by [sqlite3_errmsg()] and [sqlite3_errmsg16()]
**          are valid until the next SQLite interface call.
**
** {H12808} Calls to API routines that do not return an error code
**          (example: [sqlite3_data_count()]) do not
**          change the error code or message returned by
**          [sqlite3_errcode()], [sqlite3_errmsg()], or [sqlite3_errmsg16()].
**          [sqlite3_errcode()], [sqlite3_extended_errcode()],
**          [sqlite3_errmsg()], or [sqlite3_errmsg16()].
**
** {H12809} Interfaces that are not associated with a specific
**          [database connection] (examples:
**          [sqlite3_mprintf()] or [sqlite3_enable_shared_cache()]
**          do not change the values returned by
