Hi,

in my application I need to write a custom listener. Could you please help me to start? I've never wrote something like that. Are there any classes in C++ which I could reuse, do you know some other relevant resources? Thank you in advance!

Do you mean a listener for clients in socket programming?

In standard C++ there are no "standard" listener classes. You will be using sockets either way. You can get an API that has implemented TCP client / server classes.

IP*Works makes it easy

Since you did not specificy a platform, I cannot tell much more except on Windows you will be using winsock capability in your project.
On UNIX you use "Berkeley sockets" API.

Start here: http://en.wikipedia.org/wiki/Berkeley_sockets

Also look online for UNIX Network Programming by W. RIchard Stevens, it is the classic standby and still the best. Even if not using UNIX, it covers the sockets API in extreme detail and most samples will compile on Windows.

Essentially, for a server, you do the following:

socket()
bind()
listen()
while(true) {
   accept()   // new connection
   service connection
   close()
}

I'm slightly confused as the two selected answer are, mostly, unrelated.

It's because I'm only doing a research, not implementing yet and both answers helped me to understand some concepts. I'm sure it's fair to split points the way I did it in this case :) Thank you again
