When creating a response to a D-Bus message with
reply = l_dbus_message_new_method_return(msg);
where the original method has an empty (void) return list, is it neccessary to set the
arguments:
l_dbus_message_set_arguments(reply, "");
or can I just:
return l_dbus_message_new_method_return(msg);
from within the message handler? (without setting non-existant arguments)

either will work. The latter is what I prefer to see/use.

I don't think you have to set the arguments if there isn't any. We do
it both ways in IWD, but it doesn't seem to be required.
Thanks,
