NAME
     mtx_unlock – unlocks a previously acquired mutex

SYNOPSIS
     library “threads”
     #include <threads.h>

     int
     mtx_unlock(mtx_t *mtx);

DESCRIPTION
     The function mtx_unlock() will unlock a previously acquired mutex mtx.

     A thread can only unlock a mutex if it has been acquired by that thread
     before.

     If recursive mutex acquisition is enabled and the mutex has been acquired
     by the same thread multiple times mtx_unlock() needs to be called from
     that thread an equal number of times before any other thread can acquire
     the mutex.

RETURN VALUES
     Upon success mtx_unlock() returns thrd_success, in the case of an error
     thrd_error will be returned.
