-destroys the unnamed semaphore at the address pointed to by
-.IR sem .
-
-Only a semaphore that has been initialized by
-.BR sem_init (3)
-should be destroyed using
-.BR sem_destroy ().
-
-Destroying a semaphore that other processes or threads are
-currently blocked on (in
-.BR sem_wait (3))
-produces undefined behavior.
-
-Using a semaphore that has been destroyed produces undefined results,
-until the semaphore has been reinitialized using
-.BR sem_init (3).
-.SH RETURN VALUE

-Failure to do this can result in resource leaks on some implementations.
-.\" But not on NPTL, where sem_destroy () is a no-op..
