WaitForSingleObject() -- how long ?

[wxuf]

hi..

when an event i am waiting is signaled, the WaitForSingleObject() succeeds. but can i know how long the time is elapsed from the waiting begins ?

No, I don't think that's possible. You have to take the time right before you enter the Wait-function. Something like this:

time(&beforeWait);
WaitForSingleObject(...)
time(&afterWait);

Now you can calculate the time spent in Wait-function by doing afterWait - beforeWait.

You may prefer to use GetTickCount() if you need a resolution better than 1 second.

Or, even better than better :) use high-resolution performance counter.
See QueryPerformanceCounter and QueryPerformanceFrequency.

Thank you all..

Now I use GetTickCount() to get the interval.
