check_is_paired()

char* check_is_paired

(

GVariant *

properties

)

Return Bluetooth address if the device is paired. Else return NULL

Parameters

properties

An 'object' that holds a specific bluetooth device's metadata

Returns

: Return Bluetooth address if the device is paired. Else return NULL

Definition at line 3 of file pam_bt_pair.c.

get_paired_devices()

char** get_paired_devices

(

int *

num_of_paired

)

Return a list of Bluetooth addresses that is currently paired (connected) to the host

Approach: Use dbus to list all the bluetooth devices and see the connected property The paired property only indicates if the device has been paired with the host before and not if it is currently paired

Parameters

num_of_paired

the number of devices paired to the host NOTE: the value is set within the helper function that the function will call

Returns

: return a list of bluetooth addresses connected to the host

process_dbus_bt_list()

char** process_dbus_bt_list	(	GVariant *	result,
		int *	num_of_paired
	)

Return a list of paired devices

Parameters

num_of_paired	the number of devices that are paired NOTE: The number is set in this function
result	The object returned by request to DBUS for all managed bluetooth object

Returns

: returns a list of paired devices. Need to free
