在UNIX系统下FTP功能的编程实现

The programming of FTP in the UNIX

介绍了在UNIX系统下如何用C语言实现文件传输的功能。该方法利用了UNIX系统提供的socket功能和文件读写功能而实现的。虽然这里只讲述了如何传输文件,但若想利用它来传输其他数据都非常容易实现。这是一个典型的客户端 服务器的程序,能体现网络编程最常用的模式。

Here introduce how to realize the FTP in the UNIX using C program which is the result by using the socket function and file I/O in the UNIX.Although here only relates how to transfer file.If someone wants to transfer other data,its easy to be done.It is a typical connection——servicer program which can reflect the most common model of the network program.
