[cc'd to David E. Cross (crossd@cs.rpi.edu) and James Raynard (jraynard@freebsd.org)] I'm thinking about extending the number of signals. I like your thoughts and opinions. Why more than 32 signals? Primarily because Linux now uses more than 32 signals and I'm going to run into trouble in the Linuxulator. Also, NetBSD has increased its signals to 128. How do you want to do it? Basicly what I'm going to do is rewrite the signalling code to use a new sigset_t and provide new syscalls to use it. The current syscalls convert between the current and the new types for compatibility. I think I'm going to borrow a thought or two from Linux which allows further increasing of the number of signals without rewriting the logic, but that's basicly undecided yet and open for discussion. -- Marcel Moolenaar mailto:marcel@scc.nl SCC Internetworking & Databases http://www.scc.nl/ Amsterdam, The Netherlands tel: +31 20 4200655 To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe freebsd-hackers" in the body of the message
