|PTHREAD_COND_WAIT(3)||Library Functions Manual||PTHREAD_COND_WAIT(3)|
pthread_cond_wait() function atomically blocks the current thread waiting on the condition variable specified by cond, and unblocks the mutex specified by mutex. The waiting thread unblocks only after another thread calls pthread_cond_signal(3), or pthread_cond_broadcast(3) with the same condition variable, and the current thread reacquires the lock on mutex.
pthread_cond_wait() function will return zero. Otherwise an error number will be returned to indicate the error.
pthread_cond_wait() will fail if:
pthread_cond_wait() conforms to ISO/IEC 9945-1:1996 (“POSIX.1”).
