I'm needing to figure out how socket signaling mechanisms work under darwin.

Windows and Linux work, Darwin however does not support ePoll.

Anyone have any experience with Sockets events under OSX i386?

Thanks.

BSD's support the kqueue / kevent mechanism.

Helmut already answered that. But more importantly, there are example implementations for this stuff, see lnet.

Windows supports epoll?

No, windows doesn't offer polling socket mechanisms. They send messages to windows with the socket number - it's event driven. Kernel polling is different, but I assumed that Darwin would support it via e-Poll. I searched and found a few references to kQueue/kEvent.

Thanks for the help guys.

I'll check the iNet code to see the supporting units. Anyone have a write-up on the website for sockets and the different nuances for each of the major oses?

Afaik, Windows has select(), but I/O Completion Ports is the thing to use for scalable event notification.
