Everything works fine, but sorry for the recurrent question: where
should I use the Py_INCREF()/Py_DECREF() in code above?
That depends on the functions which are called. It should be given in
the API description. The same counts for the incoming parameters (which
are borrowed AFAIR - but better have a look).
The most critical parts are indeed
* the input parameters
and
* Py_BuildValue()
. Maybe you could as well have a look at some example code.
Especially look at the concepts called "borrowed reference" vs. "owned
reference".
And, for your other question:

You ask how to stop leaking memory? Well, simply by not leaking it :-)
Just free the memory area:
if (cRes == 0) {
PyObject* ret = Py_BuildValue("s", outdata);
free(outdata);
return ret;
}
BTW: Is there any reason for using calloc()? malloc() would probably be
faster...
