If you are talking to another program directly (no bus daemon) you would
use dbus_connection_get_unix_process_id / dbus_connection_get_unix_user
If you are using the bus daemon, you need to ask the bus daemon to call
those functions for you.
To see the methods on the bus daemon type this command:
dbus-send --print-reply --dest=org.freedesktop.DBus
In this case you want GetConnectionUnixUser and GetConnectionUnixProcessID.
There is a convenience function dbus_bus_get_unix_user() that calls
GetConnectionUnixUser, but the convenience function makes a blocking
call. There's no convenience function for the process ID one.
To get the name of the client use dbus_message_get_sender()
