WdfRequestSend Fails with STATUS_CANCELLED

NTDEV

Hi,

WdfRequestSend Fails with STATUS_CANCELLED after I purge a IOTarget. Below
is the sequence of things I am doing:

1> Purge IO Target with WdfIoTargetPurgeIoAndWait. In completion routine I
mark the request for resuse.
2> Start the IO Target with WdfIotargetStart and resend the events to IO
Target. I don’t see any failure in starting the target but when i send the
request, WdfRequestSend fails. I used WdfRequestGetStatus to get the
status and it return STATUS_CANCELLED.

Does anyone know what going wrong here?

Thanks,

Ruby

Stopping the target with purge will cancel all outstanding io and the request is left in the cancelled state. Call wdfrequestreuse to reset the state
