Example #1

File: sem.c Project: spinlock/ucore

void
exit_sem_queue(sem_queue_t *sem_queue) {
    assert(sem_queue != NULL && sem_queue_count(sem_queue) == 0);
    list_entry_t *list = &(sem_queue->semu_list), *le = list;
    while ((le = list_next(list)) != list) {
        list_del(le);
        semu_destroy(le2semu(le, semu_link));
    }
}
