=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 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
