static void select_list_enqueue(termstate_t *term, struct term_select_info *t)
{
    l4semaphore_down(&term->termsem);
    t->prev       = NULL;
    t->next       = term->select_list;
    term->select_list = t;
    l4semaphore_up(&term->termsem);
}

Example #2

File: select.c Project: ErisBlastar/osfree

static void select_list_dequeue(termstate_t *term, struct term_select_info *t)
{
    if (t)
    {
        l4semaphore_down(&term->termsem);
        if (t == term->select_list)
            term->select_list = t->next;
        else
            t->prev->next = t->next;

    }
}
