=head1 NAME

Tk::exit - End the application

=for category Binding Events and Callbacks

=head1 SYNOPSIS

    use Tk qw(exit);
    ...
    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 KEYWORDS

exit, process
