[spice-server v2 2/2] channel: Introduce logging helpers

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



This commit adds red_channel_{debug,warning,printerr}() helpers which
will prepend the log message with "channel-name:id (%p)". It also
changes various locations which were doing this manually.
