Hi all,
Not having extra semicolons is one of the strongest arguments against incuding a trailing semicolon into a statement-generating macro. Can anybody explain why having an extra semicolon is considered a potential problem by some compilers? Isn't null as good as any other number? Shouldn't an empty statement be considered as good as any other statement?
Ths issue is IIRC and AFAIK macros that are used outside of any statement blocks, i.e. the thing David Abrahams suggested that spawned this whole thread. Something like a macro that declares or defines a function: #define MAKEFOO inline void foo () { ... } and then simply used as: (... other inline functions, for example ...) MAKEFOO; The point is that after macro expansion, that semicolon I put in after the macro invocation isn't valid, because I'm not allowed to have a null statement (or any other kind of statement) at this point in the file. The presence or absence of that semicolon is what the fuss has been about. :-) ---------------------------------------------------------------------- Dave Steffen, Ph.D. "There are two ways to write error-free Software Engineer IV programs; only the third one works."
