今天介绍一个通过NetBIOS获取本机的mac地址。

什么是NetBOIS  
NETBIOS协议是由IBM公司开发，主要用于数十台计算机的小型局域网。该协议是一种在局域网上的程序可以使用的应用程序编程接口（API），为程序提供了请求低级服务的统一的命令集，作用是为了给局域网提供网络以及其他特殊功能。系统可以利用WINS服务、广播及Lmhost文件等多种模式将NetBIOS名-——特指基于NETBIOS协议获得计算机名称——解析为相应IP地址，实现信息通讯，所以在局域网内部使用NetBIOS协议可以方便地实现消息通信及资源的共享。因为它占用系统资源少、传输效率高，所以几乎所有的局域网都是在NetBIOS协议的基础上工作的。NetBIOS是Network Basic Input/Output System的简称，一般指用于局域网通信的一套API

NetBIOS is an acronym for Network Basic Input/Output System. It provides services related to the session layer of the OSI model allowing applications on separate computers to communicate over a local area network. As strictly an API, NetBIOS is not a networking protocol. Older operating systems\[clarification needed\] ran NetBIOS over IEEE 802.2 and IPX/SPX using the NetBIOS Frames (NBF) and NetBIOS over IPX/SPX (NBX) protocols, respectively. In modern networks, NetBIOS normally runs over TCP/IP via the NetBIOS over TCP/IP (NBT) protocol. This results in each computer in the network having both an IP address and a NetBIOS name corresponding to a (possibly different) host name.

**NCB结构体**  
功能：  
The NCB structure represents a network control block. It contains information about the command to perform, an optional post routine, an optional event handle, and a pointer to a buffer that is used for messages or other data. A pointer to this structure is passed to the Netbios function.  
原型：  
“\`cpp  
typedef struct \_NCB \{  
UCHAR ncb\_command;  
UCHAR ncb\_retcode;  
UCHAR ncb\_lsn;  
UCHAR ncb\_num;  
PUCHAR ncb\_buffer;  
WORD ncb\_length;  
UCHAR ncb\_callname\[NCBNAMSZ\];  
UCHAR ncb\_name\[NCBNAMSZ\];  
UCHAR ncb\_rto;  
UCHAR ncb\_sto;  
void (CALLBACK \*ncb\_post)( struct \*NCB);  
UCHAR ncb\_lana\_num;  
UCHAR ncb\_cmd\_cplt;  
UCHAR ncb\_reserve\[X\];  
HANDLE ncb\_event;  
\} NCB, \*PNCB;

**LANA_ENUM结构体**
     功能：
     The LANA_ENUM structure contains the numbers for the current LAN adapters.
    
    原型：
    ```cpp
    typedef struct _LANA_ENUM {
      UCHAR length;
      UCHAR lana[MAX_LANA];
    } LANA_ENUM, *PLANA_ENUM;
    
    
    
    
    <div class="se-preview-section-delimiter"></div>

*\* Netbios函数\**  
功能：  
The Netbios function interprets and executes the specified network control block (NCB).  
原型：  
“\`cpp  
UCHAR Netbios(  
PNCB pcnb  
);

** 注意：** Netbios is not supported on Windows Vista, Windows Server 2008, and subsequent versions of the operating system **别忘了引入lib:** <div class="se-preview-section-delimiter"></div> ```cpp #pragma comment(lib, "netapi32.lib")

最后上代码：

#include <windows.h>
    #include <stdlib.h>
    #include <stdio.h>
    #include <iostream>
    #include <strstream>
    #include <string>
    
    using namespace std;
    #pragma comment(lib, "netapi32.lib")
    
    bool GetMacAddressByNetBIOS(int nAdapterNum, string & sMAC)
    {
      // Reset the LAN adapter so that we can begin querying it 
      NCB Ncb;
      memset(&Ncb, 0, sizeof(Ncb));
      Ncb.ncb_command = NCBRESET;
      Ncb.ncb_lana_num = nAdapterNum;
      if (Netbios(&Ncb) != NRC_GOODRET) {
        char acTemp[80];
        ostrstream outs(acTemp, sizeof(acTemp));
        outs << "error " << Ncb.ncb_retcode << " on reset" << ends;
        sMAC = acTemp;
        return false;
      }
    
      // Prepare to get the adapter status block 
      memset(&Ncb, 0, sizeof(Ncb));
      Ncb.ncb_command = NCBASTAT;
      Ncb.ncb_lana_num = nAdapterNum;
      strcpy((char *)Ncb.ncb_callname, "*");
      struct ASTAT {
        ADAPTER_STATUS adapt;
        NAME_BUFFER NameBuff[30];
      } Adapter;
      memset(&Adapter, 0, sizeof(Adapter));
      Ncb.ncb_buffer = (unsigned char *)&Adapter;
      Ncb.ncb_length = sizeof(Adapter);
    
      // Get the adapter's info and, if this works, return it in standard,
      // colon-delimited form.
      if (Netbios(&Ncb) == 0) {
        char acMAC[18];
        sprintf(acMAC, "%02X:%02X:%02X:%02X:%02X:%02X",
          int(Adapter.adapt.adapter_address[0]),
          int(Adapter.adapt.adapter_address[1]),
          int(Adapter.adapt.adapter_address[2]),
          int(Adapter.adapt.adapter_address[3]),
          int(Adapter.adapt.adapter_address[4]),
          int(Adapter.adapt.adapter_address[5]));
        sMAC = acMAC;
        return true;
      }
      else {
        char acTemp[80];
        ostrstream outs(acTemp, sizeof(acTemp));
        outs << "error " << Ncb.ncb_retcode << " on ASTAT" << ends;
        sMAC = acTemp;
        return false;
      }
    }
    
    int main()
    {
      // Get adapter list
      LANA_ENUM AdapterList;
      NCB Ncb;
      memset(&Ncb, 0, sizeof(NCB));
      Ncb.ncb_command = NCBENUM;
      Ncb.ncb_buffer = (unsigned char *)&AdapterList;
      Ncb.ncb_length = sizeof(AdapterList);
      Netbios(&Ncb);
    
      // Get all of the local ethernet addresses
      string sMAC;
      for (int i = 0; i < AdapterList.length; ++i) {
        if (GetMacAddressByNetBIOS(AdapterList.lana[i], sMAC)) {
          cout << "Adapter " << int(AdapterList.lana[i]) <<
            "'s MAC is " << sMAC << endl;
        }
        else {
          cerr << "Failed to get MAC address! Do you" << endl;
          cerr << "have the NetBIOS protocol installed?" << endl;
          break;
        }
      }
    
      return 0;
    }

**缺点：**  
1 必须安装了NetBIOS  
2 必须进行额外的工作筛选想要的mac地址
