[Spice-devel] [PATCH 08/11] Add DisplayChannelClientPrivate and CursorChannelPrivate structs

Jonathon Jongsma jjongsma at redhat.com
Tue Aug 9 15:33:02 UTC 2016


These need to be introduced at the same time since cache-item.tmpl.c
assumes that both of these classes will have a cache in the same place:
either within the channel client struct itself or (now) within a priv
struct owned by the channel client.

This encapsulates private data and prepares for porting to GObject.
