Libjabberc
Libjabberc is a c++ jabber library, i'm not doing much work on this website,
so this is going to be it, try
http://sourceforge.net/projects/libjabberc/
to download the lib. It's currently at release 0.0.1, which means all basic
functionality is there: messaging works, the roster works, iqs work, presences
work, agents etc. don't work (they work if you register with them first
using another jabber client)
here are some related links:
