    zmutex_new (void);

//  Destroy a mutex container
CZMQ_EXPORT void
    zmutex_destroy (zmutex_t **self_p);

//  Lock mutex
CZMQ_EXPORT void
    zmutex_lock (zmutex_t *self);

//  Unlock mutex
CZMQ_EXPORT void
    zmutex_unlock (zmutex_t *self);

//  Try to lock mutex
CZMQ_EXPORT int
    zmutex_try_lock (zmutex_t *self);

Description

The zmutex class provides a portable wrapper for mutexes. Please do not use this class to do multi-threading. It is for the rare case where you absolutely need thread-safe global state. This should happen in system code only. DO NOT USE THIS TO SHARE SOCKETS BETWEEN THREADS, OR DARK THINGS WILL HAPPEN TO YOUR CODE.

Please add @discuss section in ../src/zmutex.c.

Example

From zmutex_test method

zmutex_t *mutex = zmutex_new ();
assert (mutex);
zmutex_lock (mutex);
zmutex_unlock (mutex); zmutex_destroy (&mutex);
