The WdfDeviceWdmGetDeviceObject method returns the Windows Driver Model (WDM) device object that is associated with a specified framework device object.
Device
A handle to a framework device object.
WdfDeviceWdmGetDeviceObject returns a pointer to a DEVICE_OBJECT structure.
A bug check occurs if the driver supplies an invalid object handle.
The pointer that the WdfDeviceWdmGetDeviceObject method returns is valid until the framework device object is deleted. If the driver provides an EvtCleanupCallback function for the framework device object, the pointer is valid until the callback function returns.
The following code example creates a tracing message that contains pointers to the WDM device objects that represent a device's PDO and FDO.
TraceEvents(
TRACE_LEVEL_INFORMATION,
AMCC_TRACE_INIT,
"PDO 0x%p, FDO 0x%p",
WdfDeviceWdmGetPhysicalDevice(device),
WdfDeviceWdmGetDeviceObject(device)
);
