Bluetooth Connectivity

[sagarp]

Hi,
I am new programmer in bluetooth technology.
I need to write sample code for searching bluetooth devices and print their name.
This has to be done in Pocket PC.
I have already sample code for this downloaded from internet.
Problem is that, there are two files Bthdef.h, and BluetoothAPI.h
I am not able to locate these files.
Can anybody tell version of SDK where these files are....

Regards,
Sagar.
