[WinPcap-users] MAC ADDRESS pcap_if_t

[Descript]

Hello list,

I would like to get the mac address of a network device. I cant use ARP
request (due some security consideration).
So i'v see a small code from Microsoft that use Netbios function....

I'v to find a function that can give to me the address, so why pcap_if_t
typedef doesn't provide local mac address ?!

(on the bottom a small idea for pcap_if_t)

typedef struct _ASTAT_ {
    ADAPTER_STATUS adapt;
    NAME_BUFFER    NameBuff [30];
}ASTAT, * PASTAT;

ASTAT Adapter;

void main (void)
{
    NCB ncb;
    UCHAR uRetCode;
    char NetName[50];

    memset( &ncb, 0, sizeof(ncb) );
    ncb.ncb_command = NCBRESET;
    ncb.ncb_lana_num = 0;

    uRetCode = Netbios( &ncb );
    printf( "The NCBRESET return code is: 0x%x \n", uRetCode );

    memset( &ncb, 0, sizeof(ncb) );
    ncb.ncb_command = NCBASTAT;
    ncb.ncb_lana_num = 0;

    strcpy( ncb.ncb_callname,  "*               " );
    ncb.ncb_buffer = (char *) &Adapter;
    ncb.ncb_length = sizeof(Adapter);

    uRetCode = Netbios( &ncb );
    printf( "The NCBASTAT return code is: 0x%x \n", uRetCode );
    if ( uRetCode == 0 )
    {
        printf( "The Ethernet Number is: %02x%02x%02x%02x%02x%02x\n",
                Adapter.adapt.adapter_address[0],
                Adapter.adapt.adapter_address[1],
                Adapter.adapt.adapter_address[2],
                Adapter.adapt.adapter_address[3],
                Adapter.adapt.adapter_address[4],
                Adapter.adapt.adapter_address[5] );
    }
