PyArg_ParseTuple() & Py_DECREF()

[rwgk at my-deja.com]

Consider the following two lines of source code at the
beginning of a C extension function:

  PyObject *O;
  if (! PyArg_ParseTuple(args, "O", &O)) return NULL;

Is it necessary to call Py_DECREF(O) before leaving the
extension function?

Thanks!
