GNU C. Ubuntu 11.

，你可能会做出 X11 客户端图形应用程序;在这种情况下使用图形工具库如 GTK 或的 Qt的
And you might make an X11 client graphical application; in that case use a graphical toolkit library like GTK or Qt
如果你想使一个控制台应用程序，使用 ncurses的或可能的 readline的
If you want to make a console application, use ncurses or perhaps readline
和你的问题，如果从字面上看，有没有意义：严格C标准不知道是什么一个键或一个按键是（唯一的I /在标准中提到O操作都涉及到 ＆LT;＆stdio.h中GT; 直通文件）。这就是为什么大多数人使用额外的库和标准（除了那些由ISO C要求的），例如。 的Posix ...

This is why most people uses additional libraries and standards (in addition of those required by ISO C), eg. Posix...
