Is it A typo in WDF DDK

NTDEV
1

typedef NTSTATUS
(*PFN_WDF_DEVICE_RESOURCE_REQUIREMENTS_QUERY)(
IN WDFDEVICE Device,
IN WDFIORESREQLIST IoResourceRequirementsList
);

Should the second argument be IN OUT? or probably be OUT since input is an
empty list?

A very trivial one which users can probably figure it out from the desc…

Thanks,

The IN/OUT describe the value itself being passed. In this case, the
KMDF handle remains the same, while you are operating on the handle and
modifying its state underneath the handle.
