socket网络编程

【实例简介】
一个简单的socket网络编程例子： 服务器代码： #include #include #include #include #pragma comment(lib,"ws2_32.lib") //这句话的意思是加载ws2_32.lib这个静态库 #define NETWORK_EVENT WM_USER+100 //如果你用mfc做开发，你可以点击菜单project-〉setting-〉link-〉object/library中添加这个静态库。 //如果你用c语言，你需要通过#pragma comment（命令来连接静态库 int main(int argc, char* argv[]){ HANDLE hThread = NULL; //判断是否输入了端口号 if(argc!=3){ printf("Usage: %sPortNumber\n",argv[1]); exit(-1); } //把端口号转化成整数 short port; if((port = atoi(argv[2]))==0){ printf("端口号有误！"); exit(-1); } WSADATA wsa; //初始化套接字DLL if(WSAStartup(MAKEWORD(2,2),&wsa)!=0){ //高字节指定了次版本号，低字节指定了主版本号，两个字节加到一起，就是你想要的Winsock库的版本号了 printf("套接字初始化失败!"); exit(-1); } //创建套接字 SOCKET serverSocket; if((serverSocket=socket(AF_INET,SOCK_STREAM,IPPROTO_TCP))==INVALID_SOCKET){ printf("创建套接字失败！"); exit(-1); } struct sockaddr_in serverAddress; memset(&serverAddress,0,sizeof(sockaddr_in)); serverAddress.sin_family=AF_INET; serverAddress.sin_addr.S_un.S_addr = htonl(INADDR_ANY); serverAddress.sin_port = htons(port); //绑定 if(bind(serverSocket,(sockaddr*)&serverAddress,sizeof(serverAddress))==SOCKET_ERROR){ printf("套接字绑定到端口失败！端口: %d\n",port); exit(-1); } //进入侦听状态 if(listen(serverSocket,SOMAXCONN)==SOCKET_ERROR){ printf("侦听失败！"); exit(-1); } printf("Server %d is listening......\n",port); SOCKET clientSocket[5],maxSocket;//用来和客户端通信的套接字 struct sockaddr_in clientAddress;//用来和客户端通信的套接字地址 memset(&clientAddress,0,sizeof(clientAddress)); int addrlen = sizeof(clientAddress); fd_set fd_read; int i=0; int j; char buf[4096]; char buff[4096]="exit"; while(1) { FD_ZERO(&fd_read); maxSocket=serverSocket; FD_SET(serverSocket,&fd_read); //FD_SET(clientSocket[i-1],&fd_read); for(j=0;j<i;j++) { FD
