Re: Get the current function used to handle control+z

in reply to Get the current function used to handle control+z

The key press Control-z is typically mapped by your termcap or terminfo database to the capability susp. Your terminal interprets that and sends a SIGSTOP signal to your foreground process. SIGSTOP is 19 on the CentOS box I looked at and 17 on the Mac OS X machine I also looked at. The kill program on your *NIX takes a signal name. kill() in Perl doesn't though the Config module stores your local system's mapping as well.

system "kill -STOP $$"; # stop self

It's a little clunky, but you can do the `kill` from within perl by counting SIGSTOP's position in `$Config{sig_name}` (which, unfortunately, is a space-separated list rather than an array.) `perl -MConfig -le 'for( split /\s/, $Config{sig_name} ) { last if /^STOP$/; $n++ } kill $n, $$'` [download] This just counts signal names until it gets to STOP, and `$n` will contain the right number.

There's no need to search signal number in `$Config` `kill STOP => $$;` [download] will work just fine.	[reply] [d/l]
