[Spice-devel] [PATCH 13/14] gobject-ify RedChannelClient heirarchy

Tue May 3 20:00:29 UTC 2016


Convert the RedChannelClient heirarchy into GObjects. Since the existing
constructors could fail and return NULL, I inherited the base channel
client from GInitable, which introduces a dependency on gio.
