This basicly how NetBSD does it. The Linux trick I like to add is to have sigset_t always be the last field in structures so that the impact of enlarging sigset_t is minimal. If you pass a size argument along with syscalls that include sigset_t, you are free to further enlarge sigset_t in the kernel without recompilation of userland tools. -- Marcel Moolenaar mailto:mar...@scc.nl SCC Internetworking & Databases http://www.scc.nl/ Amsterdam, The Netherlands tel: +31 20 4200655 To Unsubscribe: send mail to majord...@freebsd.org with "unsubscribe freebsd-hackers" in the body of the message
