Programming

I've got a program running using epoll to poll activity on a listening socket. I want to be able to output a message to the terminal when the socket is connected to from the client app. It appears that epoll doesn't throw any events on the connect but only on the socket activity. Is there any way to be notified once the client connects so that I can write a banner message to the client?

Thanks...

You are using DGRAM, or other stateless sockets? Otherwise you'll need to call accept() for the new tcp connection anyway and writing to the new fd at that time
is okay.

Since udp is connectionless the idea of a 'new' client is kind of strange. You could record client addresses via recvfrom and implement some kind of scheme to determine what 'new' means based on context you determine I guess.

Here's a barebones example from google without a write after accept().
