[systemd-devel] sd-bus object manager question

[David Härdeman]

Hi,

as an experiment I've tried porting a toy dbus daemon over to sd-bus. It 
seems to be working well so far and I have to say I really like the 
sd-bus API over the gdbus one (sd-bus feels like I'm still writing 
C...can't say the same thing about gdbus).

Now, a question...how is an object manager supposed to be implemented in 
sd-bus?

I've seen that there's a sd_bus_add_object_manager() function in 
sd-bus.h, but how would I notify the object manager when objects are 
added and removed?

Two likely candidates seemed to be:
sd_bus_emit_object_added()
sd_bus_emit_object_removed()

But calling them did not seem to do the right thing. And there seems to 
be zero usage of sd_bus_add_object_manager() in the systemd tree itself 
(though plenty of calls to sd_bus_add_node_enumerator() which might be 
related?).

So, could anyone provide me with an example of how to use 
sd_bus_add_object_manager()?

Regards,
David
