cnd_timedwait
From cppreference.com
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 the TIME_UTC based time point pointed to by time_point
has been reached, 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 |
time_point | - | pointer to a object specifying timeout time to wait until |
Return value
thrd_success if successful, thrd_timedout if the timeout time has been reached before the mutex is locked, or thrd_error if an error occurred.
