Example of Socket programming in C using TCP/IP: As we know in socket programming network nodes (sockets) are communicating with each other over the network. One socket(node) listens on a particular port at an IP, while the other socket reaches out to the other to form a connection. In ...
In addition, the book covers several new classes and capabilities introduced in the last few revisions of the Java platform. New abstractions to be covered include NetworkInterface, InterfaceAddress, Inet4/6Address, SocketAddress/InetSocketAddress, Executor, and others; extended access to low-lev...
Course objective:Learn how to implement a typical complex Socket based Programs, closely tied to thread management In this course, we will be going to build the Complete TcpServer Program in which we will cover : How to manage Multiple Clients through Multiplexing ...
Socket其实最早叫做Berkeley Socket出现于Unix系统上,简称Socket,是应用程序收发数据的一种抽象手段,和打开文件操作,允许程序读写一样,毕竟Unix哲学:“一切都是文件”嘛。Socket也是一种文件。 不同的协议栈有不同的Socket,这里只关注TCP/IP协议栈。这里的Socket分为Stream Socket,以及Datagram Socket。前者使用TCP,后者...
服务端 server.c #include <stdio.h> #include <unistd.h> #include <sys/socket.h> #include <netinet/in.h> #include <arpa/inet.h> #include <string.h> int main() { printf("服务器创建socket...\n"); int sockfd = socket(AF_INET,SOCK_STREAM,0); ...
利用系统提供函数接口,通过C语言实现对TCP 服务器(IP地址)的连接,以及收发数据。 实现过程 1、socket(2) 创建套接字 2、connect(2) 连接服务器。服务器已打开,否则会直接返回错误。 3、send(2) 向服务器发送数据。连接成功后,即可与服务器通信。
SOCKETWSAAPIsocket([in]int af,[in]int type,[in]int protocol); af:即协议域,又称为协议族(family)。常用的协议族有,AF_INET代表IPv4 AF_INET6代表IPv6等等。 type:指定socket类型。常用的socket类型有,SOCK_STREAM代表TCP连接,SOCK_DGRAM代表UDP等等 ...
简介: linux下CC++网络编程基本:socket实现tcp和udp的例子 简单的linux下socket编程,分别基于TCP和UDP协议实现的简单程序 linux下socket编程可以概括为以下几个函数的运用: socket() bind() listen() connect() accept() read() write() close()函数 基于TCP实现 流程 server代码 #include <stdio.h> #include ...
printf("socket error !"); return 0; } //绑定IP和端口 sockaddr_in sin; sin.sin_family = AF_INET; sin.sin_port = htons(8888); sin.sin_addr.S_un.S_addr = INADDR_ANY; if(bind(slisten, (LPSOCKADDR)&sin, sizeof(sin)) == SOCKET_ERROR) ...
SOCKET s,//标识一个未绑定的套接字描述符 ,它是socket()函数调用成功时返回的值 const struct sockaddr FAR* name,//是一个与指定协议有关的地址结构指针,存储了套接字的地址信息, //Winsock中使用sockaddr_in结构指定IP地址和端口信息 int namelen ...
