[libvirt-glib PATCHv5 3/7] gobject: Port GVirConnection to GTask

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

 



GSimpleAsyncResult has been deprecated in favour of GTask and with
latest glib headers, we get tons of warnings about use of deprecated
API. This patch ports the GVirConnection class to GTask.
