And what was the motivation for allowing functions of this type where C forbids them? I also notice that C++ makes the comma optional, whereas it's mandatory in C. That is, this is a legal prototype: void function2(int ...); What is the motivation for this change? Followups set to comp.lang.c++ Thanks, -Peter --- [ comp.std.c++ is moderated.
