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.
