Hi, How would I map PDWORD, a pointer to a variable of type DWORD RequiredSize that returns a value

WINSETUPAPI BOOL WINAPI SetupDiGetDeviceInterfaceDetail( IN HDEVINFO DeviceInfoSet, IN PSP_DEVICE_INTERFACE_DATA DeviceInterfaceData, OUT PSP_DEVICE_INTERFACE_DETAIL_DATA DeviceInterfaceDetailData, OPTIONAL IN DWORD DeviceInterfaceDetailDataSize, OUT PDWORD RequiredSize, OPTIONAL OUT PSP_DEVINFO_DATA DeviceInfoData OPTIONAL );
