dbus Digest, Vol 75, Issue 9

[Thierry GAYET]

Hi

Thanks for the reply ; this is was i was planning to do but thanks for the
confirmation.

I am starting my dbus session such as :

    eval `dbus-launch --sh-syntax`
    env | grep DBUS_SESSION_BUS_ADDRESS >
/var/log/thommedia_dbus/thom_dbus_addr
    export `cat /var/log/thommedia_dbus/thom_dbus_addr`

How i can get the address and pass for a dbus connexion ? Then how to use it
in order to initialize the connexion ?

Any C/C++ source code welcome.

Regards

Thierry
