I've been looking at FreeBSD's `kevent' stuff recently - they have a really nice way to wait for several different types of event, including file descriptors, processes and even when a file is modified (eg. tail -f). Does Linux or Solaris have anything like this? I had a quick look around but didn't find anything.
Linus doesn't seem to be in favour of the approach as at the end of http://kt.linuxcare.com/kernel-traffic/kt20001113_93.epl#1 he writes I've actually read the BSD kevent stuff, and I think it's classic over-design. It's not easy to see what it's all about, and the whole <kq, ident, filter> tuple crap is just silly. Looks much too complicated. But not everybody seems to agree with that: http://www.uwsg.indiana.edu/hypermail/linux/kernel/0011.0/0083.html Cheers, Manuel
