linux delayed _work使用小结

Delayed _work使用小结

直接使用delay_work将任务推迟执行，如同queue work一样。

//声明

static struct delayed_work wlan_suspend_worker;

//处理任务函数

static void xxx_worker(struct work_struct *work)

{

.........;

schedule_delayed_work(&wlan_suspend_worker,

5*HZ);

}

//初始化时将任务处理与delayed_work绑定

static int xxx_init(void)

{

int ret;

...........;

INIT_DELAYED_WORK(&wlan_suspend_worker,

xxx_worker);

}

//推出取消delayed_work

static void __exit ath6kl_sdio_exit(void)

{

........;

cancel_delayed_work(&wlan_suspend_worker);

}
