1:加载套接字库,创建套接字(WSAStartup()/socket()); 2:向服务器发出连接请求(connect()); 3:和服务器端进行通信(send()/recv()); 4:关闭套接字,关闭加载的套接字库(closesocket()/WSACleanup())。 函数介绍: 1.#include<sys/socket.h> int socket (int family, int type, int protocol); 返回值...
sockets(套接字)编程有三种,流式套接字(SOCK_STREAM),数据报套接字(SOCK_DGRAM),原始套接字(SOCK_RAW); 基于TCP的socket编程是采用的流式套接字。在这个程序中,将两个工程添加到一个工作区。要链接一个ws2_32.lib的库文件。 服务器端编程的步骤: ...
