You might find D-feet useful: https://fedorahosted.org/d-feet/ It is a DBus debugger that you can use to see what applications have listeners active, what APIs are supported, etc. I asked some time ago whether there was (a) a way to self-document DBus APIs when registering them (as you can do with the GIMP in plug-ins, for example) or (b) a way to inspect DBus and get something resembling API docs out of it, or (c) some gtk-doc or Doxygen convention we could use to document D-Bus APIs I was told "no" for a and c, and D-feet, dbus-monitor (which David mentioned in that tools wiki page) and dbus-inspector (http://www.vitavonni.de/projekte/dbus-inspector.html.en) are the best I could find.

Re: DBus Methods and Signals Introspection or Documentation
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!

Re: DBus Methods and Signals Introspection or Documentation
Thanks for all your help! As I mentioned, I am doing a middleware (for energy efficiency) project on N900, hence I need to get the device status information such as battery, WLan card, mce. I need to use DBus to communicate with other components in my work. So the refs on DBus methods and signals will be helpful. Some of such information (for example, the battery) can be queried from HAL which has a defined specification. But some are not. For example, under /com/nokia path, there are many objects like icd, wlancond and in Faheem's example, csd (don't even know what it is. I assumed circuit switch data?), which I couldn't find the docs for them. If anyone knows a general reference to all those objects, like what HAL specification does, it would be great. BTW, in dbus-send command, the --desti argument specifies the "service", meaning the interface? I always get lost with bus name (connection name) and interface. Thanks for all the help!
