Here are some places worth visiting that describe some topics in more details.

- http://www.visolve.com/squid/whitepapers/squidrtsignal.php - Describes Squid's modifications to use RT signals to polling sockets.
- http://www.linuxjournal.com/article/3985 - Old (2000), but still interesting article on how signals are implemented in Linux kernel.

It's not really everything...


The title of this article is misleading. UNIX/Linux signals is a big topic. When I was writing it I found many aspects of signals I had not known about. I'm also not a big expert, so as always: there could be bugs, not all important things may be mentioned. Comments are welcome!

Hi, typo jerk here again: page3: Moreover, it lack's features -> lacks why the signal was send -> sent page5: signals like SIGPIPE, SIGUSR1, SIGUSR1 -> SIGUSR2 signal i exits -> it This program read from it's -> reads, its Additionally when SIGUSR1 -> Additionally, when [missing comma] I hope you really, truly don't consider this as some kind of personal attack.

Thanks. I don't consider it

Thanks. I don't consider it as an attack :) Some of them are just caused by the fact that English is not my native language.

Signals - That's not everything

I wouls suggest the reading of "Advanced Programming in the Unix Environment". It does not address signals with threads, but it is the most extensive explanation of signal handling. It treats also long jumps to remove races in signal handling.
