in reply to $SIG{INT} unlink problem

So much good stuff in this thread! If Ferret figures out what's up
he should consider writing a basic tutorial on the signal handler stuff

Unless Aristotle or sauoq want to get to it first.

    Thanks for your vote of confidence, cybear...

    Unfortunately, from my inexperienced point of view, basic and signal handling are mutually exclusive - it's pretty complex. I need a few more attempts and a little more time reading the docs before I'd consider writing a tutorial on something that in the Real World often gets enough chapters to make its own book.

    Until then, read perlipc and perlfork, Chapter 16 of the Camel, and the chapter(s) on signal handling in the nearest System Programming for Unix book. I'm going to go through them again (it's been awhile) and see if I can't grok in fullness.

    I too have to decline the offer. I pick up a lot of hints on various topics mainly by the reading about experience of fellow monks, and of course also poking around in the docs, so sometimes I can offer limited help on topics I'm not actually experienced with. As stated in my above post, signal handlers are one such topic. If someone did write a lightweight tutorial on them, I would however definitely be interested in reading it; accumulating knowledge never hurts. :-)

    Makeshifts last the longest.

      accumulating knowledge never hurts
      Unless its done inside a signal handler lacking enough preallocated memory to store it.... <grin>
