in thread Unix real time signals

If you "use warnings" you'll see:

No such signal: SIGSIGRTMIN+5 at rt.pl line 5.

I can't get anything to work with the +5 stuff, but this code works:

#!/usr/bin/perl use strict; use warnings; $SIG{'RTMIN'} = \&on_sig; print $$, "\n"; while (1) { sleep 1; print ".\n"; } sub on_sig { my $sig = shift; print "somebody told me $sig"; }

When I send it a signal like this:

$ kill -s SIGRTMIN 763

I get:

somebody told me RTMIN.

-sam

(Wow, I've been gone too long. This was supposed to be a reply to the original question!)
