Hello,

I heard that there is a possible library for sending/receiving messages between two computers (ip addresses) using C/C++.

Would you know which library would do this?

Regards

In Linux, it is the kernel; in Windows, it is WinSock.

Obligatory:

Is called "Socket programing"

There's plenty of discussion of how to do this. One program opens a socket and waits to accept a connection on it. The other program connects. (The socket is minimally specified by an IP-address and a socket-number.)

It is also possible to use other libraries, such as TLS (formerly: SSL), which provides support for encrypted connections, such as the one your web-browser is right now using to talk to LQ. (See the "padlock" on the address-bar?) In general, I like to use existing high-level wrappers to do things. For instance, if you want to do "AJAX calls" in your C/C++ program (especially "C++"), you can Google-around (or GitHub around ...) for an existing library that will deal with this very-common requirement "soup to nuts."

No need to reinvent the wheel. There was a little library for C/C++ that allows to sending/receiving messages from ip to ip, some 5-6 years ago in Linux. Which one could it be?

I don't think so. I guess you need to look for some examples or tutorials. You need to create a client-server application, probably using bidirectional communication.

maybe heard of nokia lib from im ?

Now you are talking about specific applications and protocols, all of which would be built on the client/server/socket model to meet the requirements of the target protocols.

Perhaps it would be better if you would describe for us what, exactly, you are trying to achieve.

Please see the Site FAQ Welcome page, and links included there, for guidance in asking a more complete question so that others can provide help more specific to your requirements.

Yeah, what kind of information would go into these "instant messages" and what kind of program is going to send them?

libpurple?

libpurple is for chat (icq,...). With the above mentioned library, one could set a port e.g. 2222 and im directly to given ip's.

Nope. Perhaps you would like to share with the rest of the class?

oh guys, no one? I can't remember the name of the package Hopefully someone will have a clue.

The only Nokia library that anyone else knows about is Qt. Sorry.
