RE: MQTT protocol

Moths ago I was involved in a Dynamic C project and started implementing the MQTT protocol on the rabbit, taking inspiration from https://github.com/menudoproblema/libemqtt https://github.com/menudoproblema/libemqtt
Here is my project: https://code.google.com/p/dmqtt/ https://code.google.com/p/dmqtt/
You can take a look at the code: https://dmqtt.googlecode.com/svn/trunk/src/mqtt.lib https://dmqtt.googlecode.com/svn/trunk/src/mqtt.lib
Unfortunately the project suddenly stopped, and the library is far from finished (publishing is somewhat working, subscribing does not work at all) but maybe you can borrow some ideas from it.
