in reply to Unix real time signals

Try without the SIG part. I.e: $SIG{'RTMIN+5'} = \&on_sig;

    If you "use warnings" you'll see:

    No such signal: SIGSIGRTMIN+5 at 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.


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

      I thought first 3 RT signals are conserved by something. I forgot where I seen that...
