用C或者C++语言实现SOCKET通信

1、用C或者C+f言实现SOCKETS信#include#include void main()WORDwVersionRequested;WSADATA wsaData;int err;wVersionRequested = MAKEWORD(1,1);err = WSAStartup(wVersionRequested,&wsaData);if( err != 0)return;)if(LOBYTE( wsaData.wVersion ) != 1|HIBYTE( wsaData.wVersion) != 1)WSACleanup();return;)SOCKETsockSrv=soc

2、ket(AF_INET,SOCK_STREAM,0);SOCKADDR_IN addrSrv;addrSrv.sin_addr.S_un.S_addr=htonl(INADDR_ANY);addrSrv.sin_family=AF_INET;addrSrv.sin_port=htons(6000);bind(sockSrv,(SOCKADDR*)&addrSrv,sizeof(SOCKADDR);listen(sockSrv,5);SOCKADDR_IN addrClient;int len=sizeof(SOCKADDR);while(1)SOCKETsockConn=accept(

3、sockSrv,(SOCKADDR*)&addrClient,&len);char sendBuf100;sprint(sendBuf, Welcome%stontoa(addrClient.sin_addr);send(sockConn,sendBuf,strlen(sendBuf)+1,0);char recvBuf100;recv(sockConn,recvBuf);printf( "s ,recvBuf);closesocket(sockConn);WSACleanup();注：这是 Server 端；File->New->Win32 Consol

4、e Application , 工程名：TcpSrv;然后，File->New->C+ Source File ,文件 名：TcpSrv;在该工程的 Setting 的 Link 的 Object/library modules 项要加入 ws2_32.lib#include#includevoid main()WORDwVersionRequested;WSADATA wsaData;int err;wVersionRequested = MAKEWORD(1,1);err = WSAStartup(wVersionRequested,&wsaData);if( err

5、!= 0)return;if(LOBYTE( wsaData.wVersion ) != 1|HIBYTE( wsaData.wVersion) != 1)WSACleanup();return;SOCKETsockClient=socket(AF_INET,SOCK_STREAM,0);SOCKADDR_IN addrSrv;addrSrv.sin_addr.S_un.S_addr=inet_addr(“127.0.0.1");addrSrv.sin_family=AF_INET;addrSrv.sin_porthtons(6000);connect(sockClient,(SOC

6、KADDR*)&addrSrv,sizeof(SOCKAD DR);char recvBuf100;recv(sockClient,recvBuf,100,0);printf("n% s,recvBuf);send(sockClient, " Thiss zhangsan ” ,strlen( "Titis zhangsan " )+1,0);closesocket(sockClient);WSACleanup();)注：这是 Client 端；File->New->Win32 Console Application , 工程名：TcpClient;然后，File->New
