[Applies to KMDF and UMDF]
A driver's EvtIoResume event callback function resumes processing a specified I/O request after the underlying device returns to its working (D0) power state.
Queue [in]A handle to the framework queue object that is associated with the I/O request.
Request [in]A handle to a framework request object.
A driver registers an EvtIoResume callback function when it calls the WdfIoQueueCreate method. For more information about calling WdfIoQueueCreate, see Creating I/O Queues.
A driver registers EvtIoResume only for use with a power-managed queue.
The framework calls the driver's EvtIoResume callback function only if the driver's EvtIoStop callback function previously called WdfRequestStopAcknowledge with the Requeue parameter set to FALSE.
For more information about the EvtIoResume callback function, see Using Power-Managed I/O Queues.
This callback function can be called at IRQL <= DISPATCH_LEVEL, unless the ExecutionLevel member of the device or driver's WDF_OBJECT_ATTRIBUTES structure is set to WdfExecutionLevelPassive. You should not make this callback function pageable.
