mtx_trylock

Defined in header <threads.h>
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)

-

Parameters

- -
mutex - pointer to the mutex to lock

Return value

thrd_success if successful, thrd_busy if the mutex has already been locked or due to a spurious failure to acquire an available mutex, thrd_error if an error occurs.

Defect reports

-DR 470 C11 -mtx_trylock was not allowed to fail spuriously allowed
