Inter-Process Communication (IPC) techniques are what you're interested in.
This looks like some decent documentation on IPC in Linux: http://tldp.org/LDP/lpg/node7.html

how about taking a recived message and reading the ip address from it.
agein is it possible and how is it done
Where is this message recieved from, and what do you want to send it to?Quote:

ok i got the forking thing to work, i broadcast between a few servers to find a file. if a server has the file it replies to the broadcast but i need to find out the ip address for that replying server from the message is it possible?
the next stage will be to use that ip address to create a tcp connection and transfering the file
I'm sure it's possible, but I still think this is a typical "threads rather than forks" task.
Either way, I'm sure that the simplest solution is for the server to just add it's own IP address to the message when it responds to the broadcast - after all, the server must know who it is, right? [And don't worry about the extra data, it's only 4 bytes if you do it right].
