VC实现获取本机MAC地址的方法
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<stdio.h>
#include<stdlib.h>
#include<httpext.h>
#include<windef.h>
#include<Nb30.h>
intgetMAC(char*mac)
{
NCBncb;
typedefstruct_ASTAT_
{
ADAPTER_STATUSadapt;
NAME_BUFFERNameBuff[30];
}ASTAT,*PASTAT;
ASTATAdapter;
typedefstruct_LANA_ENUM
{//le
UCHARlength;
UCHARlana[MAX_LANA];
}LANA_ENUM;
LANA_ENUMlana_enum;
UCHARuRetCode;
memset(&ncb,0,sizeof(ncb));
memset(&lana_enum,0,sizeof(lana_enum));
ncb.ncb_command=NCBENUM;
ncb.ncb_buffer=(unsignedchar*)&lana_enum;
ncb.ncb_length=sizeof(LANA_ENUM);
uRetCode=Netbios(&ncb);
if(uRetCode!=NRC_GOODRET)
returnuRetCode;
for(intlana=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)
returnuRetCode;
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=(unsignedchar*)&Adapter;
ncb.ncb_length=sizeof(Adapter);
uRetCode=Netbios(&ncb);
if(uRetCode!=NRC_GOODRET)
returnuRetCode;
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]
);
return0;
}
intmain(intargc,char*argv[])
{
charmac[200];
getMAC(mac);
printf("mac:%s\n",mac);
return0;
}
另外还需要注意：必须在project->Setting里添加库文件“netapi32.lib”。
