I have a confusion regarding WdfRequestMarkCancelable. MSDN doc says when driver receives(and own) IO request, Driver should invoke this function with another callback. This call back shall be invoked by WDF framework when IO manager or another driver cancel this request. Inside this callback request can be cancelled.
But it is mentioned about another approach of using EvtWdfIoQueueIoCanceledOnQueue for handling cancelled request.
Which one should be used in driver?
