用套接字实现客户机时钟的自动设置

Use socket to carry out the time setting of a client automatically

分析了网络环境下基于 TCP/IP协议的通信应用程序间交互的最主要也是最典型的模式——客户机 /服务器模式 ,并通过一个利用网络编程界面——套接字来实现客户机在启动时向服务器询问系统当前时间的实例程序 ,阐述了该模式下 2个应用程序是如何实现通信的。

The main and the typical Client/Server mode in which application programes based on TCP/IP to communicate with each other under the network circumstances is analysized.By giving a sample which uses WINSOCK routine to make a Client get current time from a time-server when starting .It expounds in the Client/Server mode two application programes are how to communicate with each other.
