Unfortunately, this macro is defined inside the Windows SDK and it 
simply calls the C library function memcmp() which expects a (void *).

Would something like this be acceptable?

const void *guid = &(device_info_data->ClassGuid);

const void *guid_netuio = &GUID_DEVCLASS_NETUIO;

if (IsEqualGUID(guid, guid_netuio)
