Trouble with socket&bluetooth

Hi. I have trouble with follow code:

Code:

	
WSADATA wsaData;
WSAStartup(MAKEWORD( 2, 2 ), &wsaData);
SOCKET s = socket(AF_BTH, SOCK_STREAM, BTHPROTO_RFCOMM);

Result: s = INVALID_SOCKET, and GetLastError() return 10047 (address family is not supported).

Does anyone have any experience with bluetooth socket in windows???

 

you can check the list of error messages ,then decide because every error has a specific no.
