There are some things you can depend on: The order of members in the layout is the same as the order of declaration, if they are in the public/protected/private section. For POD classes, you can use the offsetof macro and get integral offsets; for other classes you can use pointers to members which encapsulate the offsets. Regards, --- [ comp.std.c++ is moderated.
