"WdfInterruptQueueDpcForIsr returns TRUE if it successfully queues the
interrupt object's EvtInterruptDpc callback function. The method
returns FALSE if the callback function was previously queued and has
What happens if DPC callback is executing, and interrupt callback is
called and queues another DPC? For example:
EvtInterruptDpc callback started EvtInterruptIsr callback started (interrupting DPC callback) EvtInterruptIsr callback calls WdfInterruptQueueDpcForIsr EvtInterruptIsr exits EvtInterruptDpc continues EvtInterruptDpc exits
So, if such sequence is executed, what is WdfInterruptQueueDpcForIsr
return value? More important, is another DPC queued in this case?
