C++ (Cpp) sem_destroy_internal Examples

Example #1

void sc_sdelete(int semid, int opt, int *errp)
{
	vrtxsem_t *sem;
	spl_t s;

	if (opt & ~1) {
		*errp = ER_IIP;
		return;
	}

	xnlock_get_irqsave(&nklock, s);

	sem = xnmap_fetch(vrtx_sem_idmap, semid);

	if (sem == NULL) {
		*errp = ER_ID;
		goto unlock_and_exit;
	}

	if (opt == 0 && xnsynch_nsleepers(&sem->synchbase) > 0) {
		*errp = ER_PND;
		goto unlock_and_exit;
	}

	/* forcing delete or no task pending */
	if (sem_destroy_internal(sem) == XNSYNCH_RESCHED)
		xnpod_schedule();

	*errp = RET_OK;

      unlock_and_exit:

	xnlock_put_irqrestore(&nklock, s);
}

Example #2

void vrtxsem_cleanup(void)
{

	xnholder_t *holder;

	while ((holder = getheadq(&vrtx_sem_q)) != NULL)
		sem_destroy_internal(link2vrtxsem(holder));

	xnmap_delete(vrtx_sem_idmap);
}
