String Pointers to explore how the pointer work -The program takes lines from standard input and keeps the last n of them in memory as it goes through standard input. When it gets to an EOF, it prints the last n lines out. You may assume n is less than 2000 and each individual line is not longer than 1000 including the newline and the null terminator.

使用非阻塞 I/O 的应用程序常常使用 poll, select, 和 epoll 系统调用. poll, select 和 epoll 本质上有相同的功能: 每个允许一个进程来决定它是否可读或者写一个或多个文件而不阻塞. 这些调用也可阻塞进程直到任何一个给定集合的文件描述符可用来读或写. 因此, 它们常常用在必须使用多输入输出流的应用程序, 而不必粘连在它们任何一个上. 相同的功能常常由多个函数提供, 因为 2 个是由不同的团队在几乎相同时间完成的: select 在 BSD Unix 中引入, 而 poll 是 System V 的解决方案. epoll 调用[23]添加在 2.5.45, 作为使查询函数扩展到几千个文件描述符的方法.-poll application instance
