Where is this guaranteed in the standard? And between what and what?

Even with normal pointers to functions, there is no such guarantee. -- James Kanze mailto:James.Kanze@dresdner-bank.com Conseils en informatique orient�e objet/ Beratung in objekt orientierter Datenverarbeitung Ziegelh�ttenweg 17a, 60598 Frankfurt, Germany Tel. +49(069)63198627 Sent via Deja.com http://www.deja.com/ Before you buy. --- [ comp.std.c++ is moderated.
