Functions marked SQLITE_PRIVATE are for internal use only. They change frequently and without notice. (One SQLITE_PRIVATE routine was change in an incompatible way and another was completely removed, just a few hours ago.) Between any two point releases of SQLite, you can expect that dozens of SQLITE_PRIVATE functions will be added, deleted, and/or modified in ways that would break any application that linked against them. Furthermore, those functions have not been tested for arbitrary inputs, but only inputs that they could have received when called from inside of SQLite. Hence, you should never, never use an SQLITE_PRIVATE function in your program. -- D. Richard Hipp drh at sqlite.org
