In celebration of all things that are rock hard, or become rock hard, here's my C++ Game Jolt Achievements library in its current state.
Current Version: 0.5
Source Code: https://github.com/hworld/gj-cpp-api
Current Issues
It is Windows only, which is really lame, mainly because it relies on Windows networking libraries. I will hopefully change this in the future.
No support for player status at the moment.
All calls are synchronous and blocking.

Shouldn't be too hard with all the existing code we have! Perhaps something cross-platform using libCURL?
