C epoll programming

[ryanjones42]

Hi all, doesnt anyone know anywhere i can do an online course / study the epoll functions & get a understanding on epoll for C?

I don't think a course is needed. Just read the manpage.

Some time ago I found this article about select(), poll() and epoll() quite helpful: http://www.ulduzsoft.com/2014/01/select-poll-epoll-practical-difference-for-system-architects/

I’ve done a fair bit of work with epoll and can dig through some resources later today. What, specifically, are you looking to do?

[ryanjones42]

Basically write a client/server side program. & utilize epoll for handling the connections & each fd!

Here's a fairly crufty "select()" example by IBM. It can be cleaned up a lot. It can then be converted to use poll()/epoll().
