[gentoo-user] Tcp Listener

[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.

My initial advice would be to use Python instead of C.

If you want to use C:

man socket
man select
man poll
man pthreads

Is this a school homework question?

He is asking because its one of the common C/C++ computer science
assignments!

In practice, perl, python are usually simpler and easier to use.

and the google-fu needed is to search for a TCP echo server to use as a
staring point.

Thank you Grant and William. I wasn't aware of python programming and now
that I have looked some stuff it seems indeed much simpler to implement it
with. I'll look into it.

It's worded like one, and it's your first post to this list I can find.
Google the topic "do my homework for me".

There's always a chance it's a genuine question though. If so, you are
unlikely to get decent answers here, this is a user-based support list
for users of Gentoo. Your question is better directed to forums that
deal with C programming as their core topic.

Well it's actually a project for a company that needs a tcp listener for
the data sent by the devices. You are right about my question. It's a bit
irrelevant with gentoo but I'm working on gentoo and I'm asking this list
because I consider its users have wide knowledge on general programming. In
fact I got a good suggestion and I believe my search is done. Thank you
anyway.

Maybe I miss your problem.But there is a command line program names
'netcat', which can send/receive TCP/UDP messages. also would be nice to
check its source code if you are interested to writing your own.
