The only know alternative to exceptions is return codes

For a very liberal meaning of "return code". You can use out
parameters, global variables (ever heard of errno?)

errno isn't a global variable

errno is a global variable.

That was true in POSIX.1, but would be completely unworkable in a
multithreaded environment.

I'm sorry but that's a meaningless statement/assertion; it's contrary
to readily available fact.

Scroll down to the section called "Redefinition of errno."

This is a newsgroup.

It's not a place to ask people to do things you want done.

If you have some argument, thebn make it: don't ask people to do things
for you.

Well, dang, notwithstanding that this is a newsgroup, did you have some argument
in mind, or not?

Now been waiting for *minutes*.

I think I'm reasonable.

No ads, and there is some C++ stuff! :-) Just going there is good. Linking
