如何使用Winsock 2？

Question

如何在Visual Studio 2008中使用Windows套接字2.我使用的是预编译的头文件,到目前为止我尝试的是:

1. 在我的StdAfx.h文件中包含了winsock2.h
2. 并在项目设置中输入WS2_32.LIB作为附加依赖项

我收到这些错误

顺便说一句,如果我在我的main.cpp(我的main()函数所在的位置)中包含winsock2.h,那么我会得到不同的错误

------ Build started: Project: TestIVR, Configuration: Debug Win32 ------

c:\documents and settings\hussain\my documents\visual studio 2008\projects\testivr\testivr\main.cpp(36) : error C2039: 'S_addr' : is not a member of 'in_addr'

以下是我的StdAfx.h头文件的内容

#pragma once

#include <stdio.h>
#include <tchar.h>
#include <windows.h>
#include <winsock2.h>

Answer 1

那么你的in_addr问题是由于事实上in_addr中没有S_addr字段引起的.有一个in_addr.s_addr重定向到in_addr.S_un.S_addr.
