I don't know anything about writing c/c++ code with Python. I have
plenty of experience with each, but not together.
But the usual C++ answer is to use an extern "C" declaration for any
function you need to be visible to the outside world. It prevents the
usual C++ name mangling.
(It therefore also prevents function overloading and can't generally be
used on class member functions)
