求翻译：If the timer was already active, sys_setalarm returns the time remaining in its reply message. A return value of zero means the timer is not active. There are several possibilities to be considered. The timer might previously have been deactivateda timer is marked inactive by storing a special value, TMR_NEVER in its e是什么意思？ 待解决

如果计时器已经启动，sys_setalarm返回其答复消息的剩余时间。一个返回值为零意味着定时器不活跃。有要考虑的几种可能性。计时器可能以前一直deactivateda定时器标记存储一个特殊的值无效，TMR_NEVER在其exp_time领域。至于C代码而言，这只是一个大的整数，所以此值显式的测试，检查是否过期时间已经过去了。定时器可能表明一个已经过去的时间。这是unlikley发生，但很容易检查。
