如何得到网卡编号(MAC地址)？
[解决方法]
用下面的代码实现：
int getMAC(char * mac)
{
NCB ncb;
typedef struct _ASTAT_
{
ADAPTER_STATUS adapt;
NAME_BUFFER NameBuff [30];
} ASTAT, * PASTAT;
ASTAT Adapter;
typedef struct _LANA_ENUM { // le
UCHAR length;
UCHAR lana[MAX_LANA];
} LANA_ENUM ;
LANA_ENUM lana_enum;
UCHAR uRetCode;
memset( &ncb, 0, sizeof(ncb) );
memset( &lana_enum, 0, sizeof(lana_enum));
ncb.ncb_command = NCBENUM;
ncb.ncb_buffer = (unsigned char *) &lana_enum;
ncb.ncb_length = sizeof(LANA_ENUM);
uRetCode = Netbios( &ncb );
if( uRetCode != NRC_GOODRET )
return uRetCode ;
for( int lana=0; lana<lana_enum.length; lana++ )
{
ncb.ncb_command = NCBRESET;
ncb.ncb_lana_num = lana_enum.lana[lana];
uRetCode = Netbios( &ncb );
if( uRetCode == NRC_GOODRET )
break ;
}
if( uRetCode != NRC_GOODRET )
return uRetCode;
memset( &ncb, 0, sizeof(ncb) );
ncb.ncb_command = NCBASTAT;
ncb.ncb_lana_num = lana_enum.lana[0];
strcpy( (char* )ncb.ncb_callname, "*" );
ncb.ncb_buffer = (unsigned char *) &Adapter;
ncb.ncb_length = sizeof(Adapter);
uRetCode = Netbios( &ncb );
if( uRetCode != NRC_GOODRET )
return uRetCode ;
sprintf(mac,"%02X-%02X-%02X-%02X-%02X-%02X",
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] );
return 0;
