[Spice-devel] [PATCH spice-server v2 2/2] red-channel: Use a single structure to hold capabilities

Frediano Ziglio fziglio at redhat.com
Wed Mar 1 13:21:06 UTC 2017


Common and channel capabilities are received together
and copied together.
As there is already a structure that holds both these capabilities
use it even for GObject property.
