You should be able to use ctypes with a C++ library, you'd just need to
know how your C++ compiler handles name mangling. Typically, changes are
made to accommodate classes, namespaces, and function overloads. Of course,
if you were to change to a different compiler (possibly including a
different version) or made minor tweaks to the functions, you'd have to
update all the Python code to use the new name mangling scheme.

Hmm...On second thought, maybe just only using functions exports with
"extern C" would be easier - or just using a C compiler.
