I'm asking because I'm using s.th. like the following idiom. Is the cleanup
part clean?
--- snip ---
a = PyArray_SimpleNew (1, &n, NPY_OBJECT);
for (i=0; i < n; i++)
{
new_obj = some_object_factory (...);
if (new_obj == NULL)
goto cleanup;
((PyObject **) PyArray_DATA (a)) [i] = new_obj;
}
return a;
cleanup:
Py_DECREF (a);
return NULL;
