what does exit(0) mean?

In UNIX C, definitely.  In ANSI C (as given in the current draft), no way.
Chapter and verse citations have been given in previous articles.  A VMS
ANSI C implementaion will return SS$NORMAL or whatever they call it when you
do "exit(0)".  Presumably, "exit(n)", for "n" != 0, can return with "n".
