Determine Bluetooth RSSI of a Device in C/C++?

PLEASE
I'm deadlocked. I have no idea how work with bluetooth in c and c++. I looked around and IOBluetoothHostController.h looks like the way to go, but after that- lost. I am trying to determine the distance of my itouch (4g) to mbp (10.6.6) in x-code (3.2.3) using c or c++ (your choice). All I need to know is whether my ipod is 4ft away or 15ft away.

/Developer/Applications/Utilities/
Bluetooth/Bluetooth Explorer-----tells me it can be done.

Come on, one of you 40 viewers must have some idea. All I want is a sample code that gets the RSSI of an iPod. Open /Developer/Applications/Utilities/Bluetooth/Bluetooth Explorer and take a look.
