                           pthread_mutex_t *restrict mutex);

  Upon successful return, the mutex shall have been locked and shall be owned 
  by the calling thread.

  Upon successful completion, a value of zero shall be returned;

  The pthread_cond_wait() function may fail if:
    [EINVAL] The value specified by cond, mutex,or abstime is invalid.
    [EINVAL] Different mutexes were supplied for concurrent pthread_cond_timedwait() or
             pthread_cond_wait() operations on the same condition variable.
    [EPERM] The mutex was not owned by the current thread at the time of the call.
  These functions shall not return an error code of [EINTR].
