实现获取本机所配置的dns服务器(windows)的IPv6地址c++代码

ipconfig /all是个方法，也有C++的：

#include
#include using namespace std;
#pragma comment(lib, "ws2_32.lib");
int main()
{ 
WSADATA wsaData;
WORD sockVersion = MAKEWORD(2, 2); 
WSAStartup(sockVersion, &wsaData); 
char lv_name[50];
gethostname(lv_name, 50);
hostent * lv_pHostent;
lv_pHostent = (hostent *)malloc(sizeof(hostent));
if( NULL == (lv_pHostent = gethostbyname(lv_name))) 
        {
           printf("get Hosrname Fail \n"); 
           return 0;
       } 
SOCKADDR_IN lv_sa; 
lv_sa.sin_family = AF_INET; 
lv_sa.sin_port = htons(6000); 
memcpy(&lv_sa.sin_addr.S_un.S_addr, lv_pHostent->h_addr_list[0],lv_pHostent->h_length); printf("%s\n", inet_ntoa(lv_sa.sin_addr)); free(lv_pHostent);
return 0;
}

这也是一个很简单的代码
