Event Notifications from Stream Class Minidriver

Hi,

How can I get Event Nofications from Stream Class to Client?
Whenever the Hardware Interrupt occurs, I want to receive notifications
from Minidriver.

So far I am coding like this on client program:

http://msdn.microsoft.com/library/default.asp?url=/library/en-us/VidCapStream/hh/vidcapstream/avsover_5e27cc99-0dca-497c-a539-6f188d46374f.xml.asp

And on the mindriver side,
1. Is it the cbEventRoutine(strMiniEvent) called when the client send
pIKsControl->KsEvent?
2. If not, How can I arrange KSEVENT_ENTRY for
StreamClassStreamNotification?

Thanks.
