Sleep Function

CPallini

Yes, it is possible: just set the Sleep interval to 1 minute (or whatever appropriate) and iterate it 30 times, then, whenever you need to shorten the wait delay, decrease the iteration limit. :)

On the other hand, if you have to use a sleep of 30 minutes, it is likely that your design could be improved. For what reason do you need to sleep so long ?

But if you give sleep 1 hour, then what happen? I think it is not possible or we need to interrupt hardware.

CPallini

Well, you may use WaitForSingleObject instead. :)

OK,but How we stop sleep function? as we already put sleep for 1 hour.

What you are looking for is a WakeUp function. Unfortunately it doesn't exist. Since your thread is effectively blocked on Sleep, you need to handle this differently. This article [^] may give you some idea of how to accomplish what you are looking for.

You cannot stop it (well, without a hammer...). :)

You say you want to sleep for 30 minutes but might at a later stage decide to alter the duration. This begs the following question: Who is doing the deciding? If you've called Sleep[^] with the full duration it obviously can't be the calling thread because it's sleeping. Some possible solutions are:

Sleep for a shorter duration and periodically check on the same thread (do this in a loop).
Use the WaitForSingleObject[^] function with the dwMilliseconds parameter set to 30 minutes and for the hHandle parameter use a synchronisation object signalled by another thread (to abort the sleep).

Depending on your requirement, you could probably use SleepEx.
