BOOL WINAPI EnumAddressCallback(REFGUID guidDataType,
DWORD dwDataSize, LPCVOID lpData,
LPVOID lpContext);

guidDataType
Globally unique identifier (GUID) indicating the type of this data chunk.
dwDataSize
Size, in bytes, of the data chunk.
lpData

The service provider should examine the GUID in the guidDataType parameter and process or store the value specified in lpData. Unrecognized values in guidDataType can be ignored.
