Get "Connection Error" when invoking dbus_bus_get()

[jinqing17]

Seems I got the reason.
That's because I started the session bus and run the application as root.
There is a measure that the root doesn't run a sesstion bus. As a result, my application didn't connect to the session bus as any user, especially as root. Is it right?
 
I still run into another question. If only root exsits and the other user can not be added, how does the session bus work and the application run? I don't know whether using the syetem bus instead would solve this issue.
 
Thanks a lot.

I started the session bus and connected to it with the same user. 
 
The commands are: 
# dbus-daemon --print-pid --print-address --config-file=/etc/dbus-1/session.conf --fork
# export DBUS_SESSION_BUS_ADDRESS=unix:path=/var/run/dbus/session_bus_socket
 
Whether should I use the system bus instead?
Thanks.

Are you connecting to a session bus started by another user?
