If the handle is signaled it does not enter a waite state ever. And if the dwMilliseconds parameter is 0 it will not enter the wait state even if it is not signaled.

Regarding its second param: dwMilliseconds MSDN says the following:

... if dwMilliseconds is zero, the function does not enter a wait state if the object is not signaled; it always returns immediately...

The documentation says otherwise. MSDN: WatiForSingleObject:

If dwMilliseconds is zero, the function does not enter a wait state if the object is not signaled; it always returns immediately.
