本文实例采用vc6.0运行环境，通过实例实现获得MAC地址的功能。

完整的实例代码如下：

#include "stdafx.h"

#include

#include

#include

#include

#include

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

{

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;

}

int main(int argc, char* argv[])

{

char mac[200];

getMAC(mac);

printf(" mac : %s \n",mac);

return 0;

}

另外还需要注意：必须在project->Setting里添加库文件“netapi32.lib”。
