[libvirt] [PATCH python 07/14] override: Replace Py{Int, Long}_FromLong with helpers
Daniel P. Berrange

Mon Dec 9 15:15:42 UTC 2013
From: "Daniel P. Berrange" <berrange at redhat.com>
Replace use of the PyInt_FromLong and PyLong_FromLongLong
with libvirt_{int,uint,longlong,ulonglong}Wrap helpers.
This isolates the need for Python3 specific code in one
place.
