B<exit>?(I<returnCode>)?; =head1 DESCRIPTION Terminate the process, returning I<returnCode> to the system as the exit status. If I<returnCode> isn't specified then it defaults to 0. If calling C<exit> from code invoked via a Tk callback then this Tk version of C<exit> cleans up more reliably than using the perl C<exit>. =head1 CAVEATS Using C<exit> from a forked process will terminate both the child process B<and> the parent process. As C<Tk::exit> is imported by default one should use C<CORE::exit> in the forked process instead. =head1 KEYWORDS exit, process =cut
