Just pitching in to say that yes, there's a lot of openal stuff out there
that's not C/C++.
In my experience (a library called opentk with C# bindings to opengl,
openal and opencl), callbacks are the single biggest issue. Oftentimes,
the only way to make them work is to write a C/C++ layer that abstracts
the callback.
So please avoid callbacks, if at all possible :)
