Thanks for the response, Mark!

The one drawback is the "native" C struct being returned by
the library may have contain several megabytes of data.
Converting these values back and forth between C and Python
might prove too much overhead.  (Correct me if I am
wrong!!!)

Just a thought, but are there examples Py_BuildValue's "O&"
modifier?  This might provide another solution...

I was wondering about this.  Guess I really need a cast:

static PyObject*
instance_method(PyObject *self, PyObject *args) {
  MyNew *real_self = (MyNew *)self;
  etc...
}


And in response to other posts, today I spend the day
learning SWIG.  Thanks for the help!
