Examples

• kqueue() in stead of poll():

• handle_events()

• {

• int i, n, timeout = TIMEOUT;

• n = poll(pfd, nfds, timeout);

• if (n <= 0)

• goto error_or_timeout;

• for (i = 0; n != 0; i++) {

• if (pfdi.revents == 0)

• continue;

• n--;

• if (pfdi.revents & (POLLERR | POLLNVAL))

• /* error */

• if (pfdi.revents & POLLIN)

• readable_fd(pfdi.fd);

• if (pfdi.revents & POLLOUT)

• writeable_fd(pfdi.fd);

• }

• ...

• }

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

• {

• if (action == ADD) {

• pfdfd.fd = fd;

• pfdfd.events = events;

• } else

• pfdfd.fd = -1;

• }
