Function Documentation

free_device_list()

void free_device_list	(	char **	device_list,
		int	num_of_devices
	)

Free the list of bluetooth MAC addresses from memory

Parameters

device_list	the list of bluetooth MAC addresses
num_of_devices	the cardinality of device array - represents the number of bluetooth devices stored in the array

Definition at line 55 of file pam_bt_misc.c.

is_dev_trusted()

int is_dev_trusted	(	FILE *	log_fp,
		char *	dev,
		char **	trusted_devices,
		int	num_of_devices
	)

Return 1 iff the given address is one of the trusted devices the user trusts

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

Returns

: 1 iff the given address is one of the trusted devices the user trusts. Else return 0

Definition at line 46 of file pam_bt_misc.c.

verify_bt_addr()

int verify_bt_addr	(	char *	address,
		FILE *	log_fp
	)

Return 1 iff the address is a valid Bluetooth Address

NOTE: Bluetooth Address is a 48 bit address. The function will treat address as a string expecting:

• 17 bit string
• Each bit can only be a hexadecimal digit other than ":" in pos 2 5 8 11 14
• i.e. 00:00:00:00:00:00

Parameters

address	the bluetooth address
log_fp	the file handle for the log file

Returns

: 1 iff the address is a valid Bluetooth Address. Else return 0 (False)
