guid

The GUID of the peer performing the role of server when authenticating.

If you are constructing a #GDBusConnection and pass %G_DBUS_CONNECTION_FLAGS_AUTHENTICATION_SERVER in the #GDBusConnection:flags property then you must also set this property to a valid guid.

If you are constructing a #GDBusConnection and pass %G_DBUS_CONNECTION_FLAGS_AUTHENTICATION_CLIENT in the #GDBusConnection:flags property you will be able to read the GUID of the other peer here after the connection has been successfully initialized.

Note that the D-Bus specification uses the term ‘UUID’ to refer to this, whereas GLib consistently uses the term ‘GUID’ for historical reasons.

Despite its name, the format of #GDBusConnection:guid does not follow RFC 4122 or the Microsoft GUID format.
