今天做一个告警检测时，需要获取本机物理网卡的所有信息，查阅MSDN后，发现可以使用windows api：GetAdaptersAddresses().

接口:

ULONG WINAPI GetAdaptersAddresses(

  __in     ULONG Family,  //指定网络协议是IPv4还是IPv6

  __in     ULONG Flags,  //指定地址类型的，可以指定单播、多播、ipv6、DNS等

  __in     PVOID Reserved,  //保留参数，传NULL

  __inout  PIP_ADAPTER_ADDRESSES AdapterAddresses,  //指向网卡信息结构体的指针，是一个链表

  __inout  PULONG SizePointer  //dapterAddresses所需数据大小的值

);

 

 

下面是使用例子：

 1 #include "stdafx.h"
 2 #include <winsock2.h>
 3 #include <ws2tcpip.h>
 4 #pragma comment(lib, "IPHLPAPI.lib")
 5 #pragma comment(lib, "Ws2_32.lib")
 6 #include <iphlpapi.h>
 7 
 8 #include <stdio.h>
 9 #include <stdlib.h>
10 
11 
12 #define MALLOC(x) HeapAlloc(GetProcessHeap(), 0, (x))
13 #define FREE(x) HeapFree(GetProcessHeap(), 0, (x))
14 
15 /* Note: could also use malloc() and free() */
