cnd_wait
| Defined in header <threads.h>
|
||
| (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.
Parameters
| cond | - | pointer to the condition variable to block on |
| mutex | - | pointer to the mutex to unlock for the duration of the block |
Return value
thrd_success if successful, thrd_error otherwise.
