int mtx_timedlock( mtx_t *restrict mutex,
const struct timespec *restrict time_point );
| (since C11) |
Blocks the current thread until the mutex pointed to by mutex is locked or until the TIME_UTC based time point pointed to by time_point has been reached.
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 to mtx_unlock on the same mutex synchronize-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).
| mutex | - | pointer to the mutex to lock |
| time_point | - | pointer to the timeout time to wait until |
thrd_success if successful, thrd_timedout if the timeout time has been reached before the mutex is locked, thrd_error if an error occurs.
