This is correct if you want to delay a thread for 10 seconds. If you want to delay an IRP for 10 seconds, then place it in a manual queue, start a timer, and have the timer remove it from the queue and complete it.

KMDF links:
Framework queue objects: http://msdn2.microsoft.com/en-us/library/aa490073.aspx
Using timers: http://msdn2.microsoft.com/en-us/library/aa490296.aspx

For non-KMDF, do the same with an IO_CSQ and a KTIMER.

What’s the purpose for the delay? The proper answer depends on what you
are in the middle of doing.
