Re: Do's and Dont's inside a signal handler

[f00li5h]

Do as little as possible, the more stuff you do the more chance that things are happening at an inconvieniant time for your application... interrupted syscalls etc

Basically, just set a flag that your application will check and reset next iteration through...

my $running = 1;
$SIG{HUP} = sub { $running =0 }
while ($running){
  do_stuff();
}

the handler only signals the outside that next time through it should stop...
