Hi!

Many of the students in a C course I teach have started to use
EXIT_SUCCESS and EXIT_FAILURE as return values from functions
(other than main).

I have never used EXIT_SUCCESS and EXIT_FAILURE for anything
else than as the return value from main, and as the argument to exit.

I don't like this new practice, but questions of style are difficult.
So I wonder: Does the standard guarantee that EXIT_SUCCESS and
EXIT_FAILURE are different?

I have looked in my old ANSI X3-159-1989,
but I guess I'm not smart enough to understand it...
