[gentoo-user] Tcp Listener

[xarman]

I'm interested in making a TCP Listener in C / C++ on Linux to accept
many connections simultaneously. I did a relative search on the Web and
although I am aware of the C language as to a certain extent, I
struggle to find a model program. Essentially, it is the listener of a
server that receives a signal and stores it in a database and do some
other functions. I know how to do the functions but I'm looking for a
way to fix the basic skeleton of listener that will be always active.
I'm not sure if I need multi threading or multi socketing for multi
connections.
If you have any knowledge on the subject or have a simple example or even
some reference in order to work on that, I'd appreciate it.
