[Spice-devel] [PATCH spice 2/2] Send name & uuid to capable clients
Marc-André Lureau
marcandre.lureau at gmail.com
Fri Mar 2 04:47:24 PST 2012
Add spice_server_set_name() and spice_server_set_uuid() that allows
the client to identify a Spice server (useful to associate settings
with a particular server)
The SPICE_MSG_MAIN_NAME and SPICE_MSG_MAIN_UUID messages are only sent
to capable clients, announcing SPICE_MAIN_CAP_NAME and
SPICE_MAIN_CAP_UUID respectively.
