Tk::exit - End the application

    use Tk qw(exit);
    ...
    B<exit>?(I<returnCode>)?;

Terminate the process, returning returnCode to the system as the exit status. If returnCode isn't specified then it defaults to 0.

If calling exit from code invoked via a Tk callback then this Tk version of exit cleans up more reliably than using the perl exit.

Using exit from a forked process will terminate both the child process and the parent process. As Tk::exit is imported by default one should use CORE::exit in the forked process instead.
