[OCLUG-devel] exit vs. return

[James Colannino]

I have one simple question (hope it's not a stupid one): why is it that
some people use exit() at the end of main() and others use return()?  I
know that return() simply returns from a function, and exit(), according
to the man page, exits from the shell (although I admit I don't quite
know what to make of this in the context of programming), but I'm not
clear as to why I've seen exit() used in some examples and return() in
others.  Thanks :)
