How to get DBus sender's information in the code

Hi Tao,

I'm not sure if I'm understanding your question correctly, but, when your 
app receives a message, you can call dbus_message_get_sender to get the 
caller's D-Bus id, and, assuming you are using dbus-daemon to route the 
messages, you can call GetConnectionUnixProcessID to get the pid of the 
process that sent the message.  It is described in the D-Bus specification
