Function Documentation

bluetooth_login()

int bluetooth_login	(	FILE *	log_fp,
		const char *	trusted_dir_path,
		const char *	username,
		char **	detected_dev
	)

Deals whether or not the device is able to login via bluetooth

Parameters

log_fp	the file handle for the log file
trusted_dir_path	the path of where all the user's trusted devices are located
username	the username of the user who wants to login
detected_dev	The bluetooth address of the device that authenticates PAM NOTE: find_trusted_paired_device(...) will allocate and set the bluetooth address. Developer must free the memory themselves

Returns

: return 1 if the trusted bluetooth device is detected

		const char *	username,
		int *	num_of_devices
	)

Populate the array with trusted devices

Parameters

log_fp	the file handle for the log file
trusted_dir_path	the path where the trusted bluetooth device files for all users are located
username	the username of the user that wants to log in

	)

Return 1 iff a trusted device for the user is connected

Parameters

log_fp	the handle of the log file
trusted_devices	the array of trusted bluetooth MAC addresses of the user
num_of_devices	the number of devices the user trusts
detected_dev	the address of the detected device NOTE: detected_dev will be set in this function if a device was detected
