int cnd_wait( cnd_t* cond, mtx_t* mutex ); | (since C11) |
Atomically unlocks the mutex pointed to by mutex and blocks on the condition variable pointed to by cond until the thread is signalled by cnd_signal or cnd_broadcast. The mutex is locked again before the function returns.
The behavior is undefined if the mutex is not already locked by the calling thread.
