[Spice-devel] [PATCH 09/14] char-device: Replace RedCharDeviceMsgToClient with RedPipeItem

Thu Apr 7 22:11:22 UTC 2016


From: Christophe Fergeau <cfergeau at redhat.com>

Now that all derived classes use a type deriving from RedPipeItem for
their RedCharDeviceMsgToClient, we can make this explicit in the
RedCharDeviceClass vfuncs, and remove the RedCharDeviceMsgToClient
typedef.
