os_sched_sleep

int
os_sched_sleep(struct os_task *t, os_time_t nticks)

OS_ENTER_CRITICAL(sr);

pull_one: ev = STAILQ_FIRST(&evq->evq_list); if (ev) { STAILQ_REMOVE(&evq->evq_list, ev, os_event, ev_next); ev->ev_queued = 0; } else { evq->evq_task = os_sched_get_current_task(); os_sched_sleep(evq->evq_task, OS_TIMEOUT_NEVER); OS_EXIT_CRITICAL(sr);

    os_sched(NULL);

    OS_ENTER_CRITICAL(sr);
    evq->evq_task = NULL;
    goto pull_one;
}
OS_EXIT_CRITICAL(sr);

return (ev);
