Module Name:
SdcaVXuTestInterface.h
Abstract:
Contains definitions to allow user mode applications to communicate
directly with private interface of SdcaVXu driver
Environment:
Kernel mode, User mode
--*/
#pragma once
// The SDCA XU Driver can add a device interface to any of the raw PDOs it creates.
//
// We'll add the GUID_DEVINTERFACE_SDCAVXU_TEST_RAWCONTROL to the initial raw PDO
// the XU driver creates (which currently isn't used for any other purpose).
//
// User-mode applications can then use this device interface to find the target
// for IOCTL requests that are intended for the XU driver.
//
// A real XU driver could add a device interface to the initial raw PDO or to
// any of the Circuit Devices it creates to support the XU driver circuits, or
// it could use WdfControlDeviceInitAllocate to create a Control Device Object
// to accept IOCTL requests from user mode (though a Control Device Object
// cannot be used with WdfDeviceCreateDeviceInterface and would instead be
// used with WdfDeviceCreateSymbolicLink)
//
// A real XU driver could also use WdfDeviceInitAssignName to enable user-mode
// applications to call CreateFile for the device.
