_WDF_DISPATCH_IRP_TO_IO_QUEUE_FLAGS enumeration

Description

[Applies to KMDF only]

The WDF_DISPATCH_IRP_TO_IO_QUEUE_FLAGS enumeration type defines flags that the driver can specify when it calls WdfDeviceWdmDispatchIrpToIoQueue.

Constants

`WDF_DISPATCH_IRP_TO_IO_QUEUE_NO_FLAGS:0x00000000`

No flags are set.

`WDF_DISPATCH_IRP_TO_IO_QUEUE_INVOKE_INCALLERCTX_CALLBACK:0x00000001`

Specifies that the framework should call the EvtIoInCallerContext callback function before inserting the request into the queue.

`WDF_DISPATCH_IRP_TO_IO_QUEUE_PREPROCESSED_IRP:0x00000002`

Specifies that the IRP was preprocessed by the driver's EvtDeviceWdmIrpPreprocess callback function. Accordingly, the framework adjusts the IRP's stack location to the next entry before inserting it into the queue.

Remarks

For more information about specifying queues for IRPs as they arrive, see Dispatching IRPs to I/O Queues.
