Using SQLite

Name

sqlite3_mutex_alloc() — Allocate a new mutex lock

Definition

sqlite3_mutex* sqlite3_mutex_alloc( int type );

type

The desired type of mutual exclusion lock.

Returns

A newly allocated and initialized mutual exclusion lock.

Description

This function allocates and initializes a new mutual exclusion lock of the requested type. Applications can request an SQLITE_MUTEX_RECURSIVE or SQLITE_MUTEX_FAST lock. A recursive lock must support and properly reference-count multiple enter/leave calls by the same thread. A fast mutex does not need to support anything other than simple enter/leave semantics. Depending on the threading library, a fast lock may not actually be any faster than a recursive lock.

Any application mutex acquired through sqlite3_mutex_alloc() should eventually be freed with sqlite3_mutex_free().
