[maemo-developers] DBus Methods and Signals Introspection or Documentation

[From: Wei Li]

Hi Daniil,

So you mean the API references are object (component) dependent hence there
is no unified reference to all the services of /com/nokia objects? I've got
to say it is a little bit inconvenient. A unified reference document will be
much helpful. So how about mce and icd? I found the dbus-names.h File
Reference but no luck with icd in the same page.

Thanks for the help!

Cheers,
Wei
