How do you use AIO and epoll together in a single event loop?

Question

How can you combine AIO and epoll together in a single event loop?

Google finds lots of talk from 2002 and 2003 about unifying them, but its unclear if anything happened, or if it's possible.

Has anyone rolled-their-own with an epoll loop using eventfd for the aio signal?

Answer 1

try libevent:

http://www.monkey.org/~provos/libevent/

there are patches to support both.

Answer 2

Tried eventfd with epoll?

"A key point about an eventfd file descriptor is that it can be monitored just like any other file descriptor using select(2), poll(2), or epoll(7)."

Answer 3

FreeBSD supports AIO together with Kqueue, the AIO completion can be monitored by the Kqueue interface.

Answer 4

you can see http://www.xmailserver.org/eventfd-aio-test.c for a sample of aio and eventfd
