int mtx_timedlock(mtx_t*restrict mutex, conststruct timespec*restrict time_point); | (since C11) | |
Blocks the current thread until the mutex pointed to bymutex is locked or until theTIME_UTC based absolute calendar time point pointed to bytime_point has been reached.
Since this function takes an absolute time, if a duration is required, the calendar time point must be calculated manually.
The behavior is undefined if the current thread has already locked the mutex and the mutex is not recursive.
The behavior is undefined if the mutex does not support timeout.
Prior calls tomtx_unlock on the same mutexsynchronize-with this operation (if this operation succeeds), and all lock/unlock operations on any given mutex form a single total order (similar to the modification order of an atomic)
