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, or until a spurious wake-up occurs. The mutex is locked again before the function returns.
The behavior is undefined if the mutex is not already locked by the calling thread.
| cond | - | pointer to the condition variable to block on |
| mutex | - | pointer to the mutex to unlock for the duration of the block |
thrd_success if successful, thrd_error otherwise.
|
(C11) | blocks on a condition variable, with a timeout (function) |
