Is there anything that describes "timer
sockets" (PF_TIMER). I've
never seen these before and was wondering what problem they solved.
Briefly, they
provide a file-descriptor interface to the timer
facilities underlying setitimer(ITIMER_REAL) and SIGALRM. humm. I guess they would also allow you to have
multiple timers, and
you can tell which one fired by the fd...
Yes. That's another reason I find them useful - you don't have to keep
your own list of timers and constantly pick out the next one to expire,
simplifying code.
