[libvirt PATCH 04/10] remote: consistently use flags for passing ro/user/autostart props

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



We have helper methods that return boolans for ro/user/autostart
properties. We then pack them into a flags parameter, and later
unpack them again. This makes te code consistently use flags
throughout.
