MSN Messenger Library?
Author
I'm looking for a library that implements the MSN messenger protocol and is written in C/C++ (preferably C++). It would be nice if it supported MSN display images. I know there is DotMSN, but that is for .NET only, and portability matters to me. I also know of libmsn, but the development seems halted and they support very minimal features (excluding display images).
I've also thought of taking apart an open source MSN client... But I couldn't find one with the features I wanted written entirely in C++.
Any help would be appreciated...
I think there's a branch of gaim called libgaim which basically gives you all the IM protocol support of gaim minus all the UI etc so you can build it into your own applications.

That would be quite interesting, but do you have any idea where it can be found? I can only seem to find talks about "when GAIM will be done" dating from 2003 (hopefully it is done?)

You might also be able to do something similar with Miranda-IM, another open source IM client. They use plugin DLL's to connect to various networks so in theory, if you use the plugin DLL's the same way, you might be able to support the various IM networks.
I recently wrote an MSN bot to automate the last bits of my social life. The library I used is for C# though, but hell, if your fluent in C++ you can pickup C# in a day ( C -> C# takes a week, in my experience ).
DotMSN - .NET Messenger Library
The documentation is horrible; its for the programmers, not the end user. Go to www.planet-source-code.com download the dos-console code that demonstrates how to use this library, and learn from that.

This is pretty much the only source I used: http://www.hypothetic.org/docs/msn/index.php
My client can connect and do basic MSN stuff, but it doesn't support images or anything. The reason is, that part of the MSN protocol is when you recieve a challenge message, the server expects you to MD5 hash some value with another value. The problem is that one of the values is unknown (nobody seems to know how these values were reached), and the only known listed ones are for older protocol versions. I don't know how other clients do display images and the like.
Also, the newer protocols haven't been taken apart completely yet.
There's a version of my code uploaded Here (VC 6 workspace) which includes OpenSSL stuff for the HTTPS authentication. It's been ages since I looked at it though, and the code is a bit odd. As I said, it doesn't implement a lot of stuff, but it should be a reasonablr starting pooint.
Let me know if there's any issues with it. The protocol is ugly as hell, just look at CMSN::AttemptLogin in MSN.cpp...

I might just end up writing some kind of plugin *in* Miranda-IM or *in* gaim so that my software can use the IM software as it is. Surely someone has figured out display images since Trillian does it...

Unfortunately no, I've seen it mentioned in various places but I've never found somewhere which actually has the straight library for D/L. Adium purports to use it, so you may find the library by poking around in the source (I took a brief look through the SVN tree and found a few references to it but nothing that actually looked like the libgaim source), it may be sitting around in the gaim CVS as well.

I would also be interested in documentation on how to write plugins for IM software, assuming that can allow me to do what I want (use the IM software to allow my own software to communicate over MSN, and possibly other networks).
