[Applies to KMDF only]
The WdfFdoGetDefaultChildList method returns a handle to a specified device's default child list.
Syntax
WDFCHILDLIST WdfFdoGetDefaultChildList(
[in] WDFDEVICE Fdo
);
Parameters

A handle to a framework device object.
Return value
If the operation succeeds, WdfFdoGetDefaultChildList returns a handle to the default child list that is associated with the device that is specified by Fdo. Otherwise the method returns NULL.
A system bug check occurs if the driver supplies an invalid object handle.
