[libvirt] [libvirt-php][PATCH 7/8] virDomainGetXMLDesc: Free returned value
Michal Privoznik
mprivozn at redhat.com
Thu Oct 1 14:14:48 UTC 2015
It's caller responsibility to free the returned value when no
longer needed. Moreover, some functions are rewritten so that
they use the fancy APIs we have (e.g. virDomainAttachDeviceFlags
instead of dumping domain XML, appending new disk there and
defining again).
