.Sh DESCRIPTION
The
.Fn sqlite3_mutex_alloc
interface takes a single argument which is one of these integer constants.
.Pp
The set of static mutexes may change from one SQLite release to the
next.
Applications that override the built-in mutex logic must be prepared
to accommodate additional static mutexes.
.Sh IMPLEMENTATION NOTES
These declarations were extracted from the
interface documentation at line 8178.
