int mtx_lock( mtx_t* mutex ); | (since C11) |
Blocks the current thread until the mutex pointed to by mutex
is locked.
The behavior is undefined if the current thread has already locked the mutex and the mutex is not recursive.
Prior calls to mtx_unlock
on the same mutex synchronize-with this operation, 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_error
otherwise.
