WaitForSingleObject()精度 [英] WaitForSingleObject() accuracy

问题描述

我使用了WaitForSingleObject函数，并让我的线程休眠了将近24小时(以毫秒为单位).
但是我注意到线程在目标时间之前15秒醒了(没有信号！).

是什么原因导致这种早期唤醒?

提前谢谢..

Hi,

i use the function WaitForSingleObject, and let my thread to sleep for almost 24 hours (in milliseconds).
However I''ve noticed that the thread woke up 15 seconds before the destination time (it was not signaled!).

what might have caused this early wake up?

Thanks in advance..
Nir.

推荐答案

精确度与准确性不同 [ ^ ]-基本上，它后面的计时器不是很准确.

Precision is not the same as accuracy[^] - basically, the timer behind it isn''t very accurate.

是Xp还是Vista?
如果是Vista，则可能是HPET.

Is it Xp or Vista?
If it is Vista then HPET might be the cause.
