想用getaddrinfo函数进行域名解析，用vc6.0，但是出现好多错误

[yiyinianhua2011]

下面是在网上找得例子：

#include "winsock2.h"
#include "windows.h"

#include "stdio.h"
#include "Ws2tcpip.h"
#include "string.h"


#pragma comment(lib, "Ws2_32.lib") // getaddrinfo 需要的 lib

int main(int argc, char * argv[])
{
const char *strDomain2Resolve = "gipv6.aulddays.com";

// 初始化 Winsock
WSADATA wsaData;
int nStatus = WSAStartup(MAKEWORD(2,2), &wsaData);
if (NO_ERROR != nStatus)
{
printf("WSAStartup() 错误\n");
return -1;
}

addrinfo Hints, *AddrList;
memset(&Hints, 0, sizeof(Hints));
Hints.ai_family = PF_INET6; // IPv6 address family

// 进行域名解析
nStatus = getaddrinfo(strDomain2Resolve, NULL, &Hints, &AddrList);
if (NO_ERROR != nStatus)
{
// 处理出错的情况，
// 例如目标域名没有对应的 AAAA 记录
printf("getaddrinfo() 失败，错误信息为 %d: %s\n",
nStatus, gai_strerror(nStatus));
return -1;
}

// 打印所有找到的地址（一个域名可能对应多个 IP 地址）
printf("已解析出下列地址:\n");
char pBuf[64]; // 打印缓冲
for(addrinfo *i = AddrList; i; i = i->ai_next)
{
// 取得一个解析出的地址
in6_addr DnsAddr = ((sockaddr_in6 *)i->ai_addr)->sin6_addr;
// 得到可打印版本
inet_ntop(AF_INET6, &DnsAddr, pBuf, 64);
printf("%s\n", pBuf);
}

// 一般来说，客户端程序使用解析出的 IP 列表中的第一个即可
// （如果解析出多个地址的话）
in6_addr AddrToUse = ((sockaddr_in6 *)AddrList->ai_addr)->sin6_addr;

freeaddrinfo(AddrList);

WSACleanup();
}




下面是出现的错误：

好像是因为没有最新的Microsoft Platform SDK，哪位朋友给我个sdk也行。。。

装个vs2005 vs2008不就行了

好吧，谢谢了。。。
