GI.Gio.Objects.DBusAuthObserver

The DBusAuthObserver type provides a mechanism for participating in how a DBusServer (or a DBusConnection) authenticates remote peers. Simply instantiate a DBusAuthObserver and connect to the signals you are interested in. Note that new signals may be added in the future

# {auth-observer}

For example, if you only want to allow D-Bus connections from processes owned by the same uid as the server, you would use a signal handler like the following:

C code

static gboolean
on_authorize_authenticated_peer (GDBusAuthObserver *observer,
                                 GIOStream         *stream,
                                 GCredentials      *credentials,
                                 gpointer           user_data)
{
  gboolean authorized;

  authorized = FALSE;
  if (credentials != NULL)
    {
      GCredentials *own_credentials;
      own_credentials = g_credentials_new ();
      if (g_credentials_is_same_user (credentials, own_credentials, NULL))
        authorized = TRUE;
      g_object_unref (own_credentials);
    }

  return authorized;
}
