Dev-cpp下的一个socket的例子
这个例子很简单，服务端是单线程的，一般来说实际应用中多采用多线程方式监听客户请求的。先列客户端的代码：Client.h
#ifndef _SERVERSOCKET_H
http://images.csdn.net/syntaxhighlighting/OutliningIndicators/None.gif#define _SERVERSOCKET_H
http://images.csdn.net/syntaxhighlighting/OutliningIndicators/None.gif＃i nclude <sys/types.h>
http://images.csdn.net/syntaxhighlighting/OutliningIndicators/None.gif//! 下面是根据操作系统自动加载所需的库和头文件
http://images.csdn.net/syntaxhighlighting/OutliningIndicators/None.gif#ifdef WIN32
http://images.csdn.net/syntaxhighlighting/OutliningIndicators/None.gif ＃i nclude <winsock2.h>
http://images.csdn.net/syntaxhighlighting/OutliningIndicators/None.gif #pragma comment(lib,"ws2_32.lib")
http://images.csdn.net/syntaxhighlighting/OutliningIndicators/None.gif#else
http://images.csdn.net/syntaxhighlighting/OutliningIndicators/None.gif ＃i nclude <sys/socket.h>
http://images.csdn.net/syntaxhighlighting/OutliningIndicators/None.gif#endif
http://images.csdn.net/syntaxhighlighting/OutliningIndicators/None.gif＃i nclude <string>
http://images.csdn.net/syntaxhighlighting/OutliningIndicators/None.gif＃i nclude <iostream>
http://images.csdn.net/syntaxhighlighting/OutliningIndicators/None.gifint WSAStartup
http://images.csdn.net/syntaxhighlighting/OutliningIndicators/None.gif(
http://images.csdn.net/syntaxhighlighting/OutliningIndicators/None.gif WORD wVersionRequested,
http://images.csdn.net/syntaxhighlighting/OutliningIndicators/None.gif LPWSADATA lpWSAData
http://images.csdn.net/syntaxhighlighting/OutliningIndicators/None.gif);
http://images.csdn.net/syntaxhighlighting/OutliningIndicators/None.gif
http://images.csdn.net/syntaxhighlighting/OutliningIndicators/None.gifusing namespace std;
http://images.csdn.net/syntaxhighlighting/OutliningIndicators/None.gifclass CClient
http://images.csdn.net/syntaxhighlighting/OutliningIndicators/ExpandedBlockStart.gifhttp://images.csdn.net/syntaxhighlighting/OutliningIndicators/ContractedBlock.gif...{
http://images.csdn.net/syntaxhighlighting/OutliningIndicators/InBlock.gif int m_sockfd;
http://images.csdn.net/syntaxhighlighting/OutliningIndicators/InBlock.gif struct sockaddr_in m_addr;
http://images.csdn.net/syntaxhighlighting/OutliningIndicators/InBlock.gifpublic:
http://images.csdn.net/syntaxhighlighting/OutliningIndicators/InBlock.gif CClient(const string& strAddr, int iPort);
http://images.csdn.net/syntaxhighlighting/OutliningIndicators/InBlock.gif ~CClient();
http://images.csdn.net/syntaxhighlighting/OutliningIndicators/InBlock.gif BOOL Connect();
http://images.csdn.net/syntaxhighlighting/OutliningIndicators/ExpandedBlockEnd.gif};
http://images.csdn.net/syntaxhighlighting/OutliningIndicators/None.gif#endif
定义文件Client.cpp
<div style="padding-right: 5.4pt; padding-left: 5.4pt; background: #e6e6e6; padding-bottom: 4px; width: 95%; padding-top: 4px;">http://images.csdn.net/syntaxhighlighting/OutliningIndicators/None.gif＃i nclude "Client.h"

http://images.csdn.net/syntaxhighlighting/OutliningIndicators/InBlock.gif int err = WSAStartup( MAKEWORD(2, 2), &wsaData );
http://images.csdn.net/syntaxhighlighting/OutliningIndicators/InBlock.gif if (err == SOCKET_ERROR)
http://images.csdn.net/syntaxhighlighting/OutliningIndicators/InBlock.gif cout << "WSAStartup error" << endl;
