Examples

• kqueue() in stead of poll():

• handle_events()

• {

• int i, n;

• struct timespec timeout = { TMOUT_SEC, TMOUT_NSEC };

• n = kevent(kq, ch, nchanges, ev, nevents, &timeout);

• if (n <= 0)

• goto error_or_timeout;

• for (i = 0; i < n; i++) {

• if (evi.flags & EV_ERROR)

• /* error */

• if (evi.filter == EVFILT_READ)

• readable_fd(evi.ident);

• if (evi.filter == EVFILT_WRITE)

• writeable_fd(evi.ident);

• }

• ...

• }

• update_fd(int fd, int action, int filter)

• {

• EV_SET(&chnchanges, fd, filter, action == ADD ? EV_ADD :

• EV_DELETE, 0, 0, 0);

• nchanges++;

• }
