man Tk::exit () - End the application
NAME
Tk::exit - End the application
SYNOPSIS
use Tk qw(exit);
...
B<exit>?(I<returnCode>)?;
DESCRIPTION
Terminate the process, returning returnCode to the system as the exit status. If returnCode isn't specified then it defaults to 0.
If calling CWexit from code invoked via a Tk callback then this Tk version of CWexit cleans up more reliably than using the perl CWexit.
KEYWORDS
