[Spice-devel] [PATCH spice-server] spice_protocol: Update many names
Frediano Ziglio
fziglio at redhat.com
Thu Oct 10 14:56:30 UTC 2019
Using an old "renames" file found in spice-protocol repository
I update some old names in the documentation protocol.
Also updated some other names manually.
I processed the file and fixed some code indentation.
File looks much more up to date.
