I am writing a filter driver (KMDF) which needs to initiate its own reading of the underlying device for our purpose. I have a EvtWdfDeviceFileCreate/EvtFileClose callback to track the fileobject creation/deletion and plan to use these file object(s) when reading the device. I am using WdfRequestCreate to create a new framework request, allocated a framework memory and use WdfIoTargetFormatRequestForRead. However, how do I set appropriate file object (I know which one to use) for the newly created request before sending it down the stack?
