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

CAVEATS
       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.
