Defined in header
Atomically locks 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, or until the TIME_UTC based time point pointed to by
time_point has been reached. The mutex is locked again before the function returns.
The behavior is undefined if the mutex is not already locked by the calling thread.
