accepting cStringIO in an extension

I want to accept a cStringIO object in a function in a python extension
module. How do I do this?

e.g.,

static PyObject *myfunc(PyObjec t *self, PyObject *args)
{
PyObject *cstringio;
if (!PyArg_ParseTu ple(args, "O:cStringI O", &cstringio)) {
PyErr_SetString (PyExc_ValueErr or,
"value must be a cstringio");
return NULL;
}
/* how to get at the data buffer or call read() on cstringio? */

}

I understand that I probably want PyEval_CallObje ct(), but I don't know
how to get at the read() method of cstringio.

Thanks,
Gary
