# swoole\_atomic->wakeup
喚醒處于`wait`狀態的其他進程。
~~~
function swoole_atomic->wakeup(int $n = 1);
~~~
* 當前原子計數如果為`0`時，表示沒有進程正在`wait`，`wakeup`會立即返回`true`
* 當前原子計數如果為`1`時，表示當前有進程正在`wait`，`wakeup`會喚醒等待的進程，并返回`true`
* 如果同時有多個進程處于`wait`狀態，`$n`參數可以控制喚醒的進程數量
* 被喚醒的進程返回后，會將原子計數設置為`0`，這時可以再次調用`wakeup`喚醒其他正在`wait`的進程
