The length of the string in characters or zero.

int authenticate	(	char *	address,
		char *	pinInput,
		BLUETOOTH_DEVICE_INFO *	deviceInfo,
		int	xml
	)

Authenticates device.

Tries to authenticate device, if already authenticated this does nothing. If pinInput is Null tries to authenticate with most common pin codes: 0000, 1111, 2222, 3333, 4444, 5555, 6666, 7777, 8888, 9999, 1234 If pinInput is not null tries to authenticate with that one.

Parameters:

	address	Address to device
	pinInput	null terminated string as Pin Code
	deviceInfo	Bluetooth device info
	xml	tells that xml print wanted

Returns:

Returns zero if no error, -1 if error, -2 if already authenticated

int checkForWinSock

(

)

Check for WinSock and Initialize it.
