|
||
|
|
.B #include <libkybluetooth.h>
|

|
||
|
|
Link with \fI\-lkybluetooth\fP.
|
||
|
|
.SH "Detailed Description"
|
||
|
|
The main function of the interface is to obtain the link policy of Bluetooth.
|
||
|
|
.PP
|
||
|
|
The argument
|
||
|
|
.I id
|
||
|
|
is the device ID of Bluetooth.
|
||
|
|
.SH "RETURN VALUE"
|
||
|
|
On success, returns the Bluetooth link policy of type char*; The returned string needs to be released by
|
||
|
|
.I free
|
||
|
|
.PP
|
||
|
|
On error, return
|
