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

default one should use CORE::exit in the forked process instead.
