A yes, I just figured it out myself. Being accustomed to Python I keep 
forgetting that with C you can't just return arbitrary types from 
functions and have to use all those scary pointers ;-)

The ctypes tutorial states:

"ctypes tries at its best to protect you from calling functions with the 
wrong number of arguments. Unfortunately this only works on Windows."

which is really a pity!
