int mtx_trylock( mtx_t *mutex ); | (since C11) |
Tries to lock the mutex pointed to by mutex
without blocking. Returns immediately if the mutex is already locked.
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 |
thrd_success
if successful, thrd_busy
if the mutex has already been locked, thrd_error
if an error occurs.
(C11) | blocks until locks a mutex (function) |
(C11) | blocks until locks a mutex or times out (function) |
(C11) | unlocks a mutex (function) |
