:-) Yes. From the specification (and indeed the documentation of
tp_cli_connection_run_connect):

So, Connect returning successfully just means that the connection
manager will start trying to connect.

Having created the Connection, you should connect to the StatusChanged
signal, then call Connect. The connection will emit
StatusChanged(Connecting, Requested), and subsequently either emit
StatusChanged(Connected, None_Specified) if the connection succeeds, or
StatusChanged(Disconnected, Authentication).

For the sake of your example, the StatusChanged handler probably just
wants to log a message when the new state is Connecting. If it gets
Connected, it can start kicking off the relevant method calls to list
contacts, and subsequently call Disconnect() which will cause
StatusChanged(Disconnected, Requested) (at which point you probably want
to g_main_loop_quit () so the example exits). If it gets Disconnected
for any reason other than requested, it should log the reason (which in
the passwordTODO case will be Authentication_Failed) and
g_main_loop_quit ().
