exit(3pm) User Contributed Perl Documentation exit(3pm)
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.
