I don't really understand what you mean, could you please explain
exactly what you are trying to do so I can get a better grasp on what
you mean?

No, that is incorrect, avahi exposes a very complete API over dbus
including both resolving, browsing and publishing.

You may want to check out the example programs, and also the DBUS
introspect files if you plan to use DBUS from a language (and not C,
where we have an API, there are good python examples too)
