主要使用幫助函數GetAdapterInfo便可。

VS成功實例：

 1 // getMac.cpp : 定義控制檯應用程序的入口點。  2 //  3 
 4 #include "stdafx.h"
 5 #include <windows.h>
 6  #include <stdio.h>
 7  #include "Iphlpapi.h" //包含對IP幫助函數的定義

10  u_char g_ucLocalMac[6]; 11  DWORD g_dwGatewayIP; 12  DWORD g_dwLocalIP; 13  DWORD g_dwMask; 14  BOOL GetGlobalData() 15  { 16      PIP_ADAPTER_INFO pAdapterInfo = NULL; 17      ULONG ulLen = 0; 18      //爲適配器結構申請內存
19      ::GetAdaptersInfo(pAdapterInfo,&ulLen); 20      pAdapterInfo = (PIP_ADAPTER_INFO)::GlobalAlloc(GPTR,ulLen); 21      //取得本地適配器結構信息
22      if(::GetAdaptersInfo(pAdapterInfo,&ulLen) == ERROR_SUCCESS) 23  { 24          if(pAdapterInfo != NULL) 25  { 26              memcpy(g_ucLocalMac,pAdapterInfo->Address,6); 27              g_dwGatewayIP = ::inet_addr(pAdapterInfo->GatewayList.IpAddress.String); 28              g_dwLocalIP = ::inet_addr(pAdapterInfo->IpAddressList.IpAddress.String); 29              g_dwMask = ::inet_addr(pAdapterInfo->IpAddressList.IpMask.String); 30  } 31  } 32  
33      printf("\n ---------------------本地主機信息---------------------\n\n"); 34      in_addr in; 35      in.S_un.S_addr = g_dwLocalIP; 36      printf(" IP Address : %s\n",::inet_ntoa(in)); 37  
38      in.S_un.S_addr = g_dwMask; 39      printf(" Subnet Mask : %s\n",::inet_ntoa(in)); 40  
41      in.S_un.S_addr = g_dwGatewayIP; 42      printf(" Default Gateway:%s\n",::inet_ntoa(in)); 43  
44      u_char *p = g_ucLocalMac; 45      printf(" MAC Address:%02X-%02X-%02X-%02X-%02X-%02X\n",p[0],p[1],p[2],p[3],p[4],p[5]); 46  
47      printf("\n\n"); 48  
49      return TRUE; 50  } 51 
52 int _tmain(int argc, _TCHAR* argv[]) 53 { 54  GetGlobalData(); 55     return 0; 56 }

結果以下：
