SYNOPSIS

#include <sqlite3.h>

#define SQLITE_MUTEX_FAST
#define SQLITE_MUTEX_RECURSIVE
#define SQLITE_MUTEX_STATIC_MAIN

#define SQLITE_MUTEX_STATIC_VFS2
#define SQLITE_MUTEX_STATIC_VFS3

DESCRIPTION

The sqlite3_mutex_alloc() interface takes a single argument which is one of these integer constants.

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.

IMPLEMENTATION NOTES

These declarations were extracted from the interface documentation at line 8178.
