Atomar sperrt der Mutex, auf den durch
mutex und blockiert unter der Bedingung, auf die variablen cond bis der Faden durch cnd_signal oder cnd_broadcast oder bis der TIME_UTC basierenden Zeitpunkt, auf den durch time_point erreicht signalisiert wird. Der Mutex wieder bevor die Funktion zurückkehrt gesperrt .Original:
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.
