C++企业信息管理系统
我是在Linux Ubuntu12.04系统下编写，所以Windows下可能会遇到一些问题，将getch.h替换成conio.h
我并没有完全按照设计文档写，会有出入请自行斟酌。数据的一些处理可能没有过多的检查，可自行修改。
使用说明
终端运行 make 编译
终端运行 ./a
相关资料
可以参考设计文档
C + + enterprise information management system
I am writing under Linux Ubuntu 12.04 system, so I may encounter some problems under windows. Replace getch. H with conio. H
I didn't write it completely according to the design documents. Please consider the difference. Some processing of data may not be checked too much and can be modified by itself.

1* Why ?
-_-_-_-_-_
Why not ? :) I ve began to work on my own implementation of the ssh protocol
because i didn t like the currently public ones.
Not any allowed you to import and use the functions as a powerful library,
and so i worked on a library-based SSH implementation which was non-existing
in the free and open source software world.
2* How/Who ?
-_-_-_-_-_-_-_
If you downloaded this file, you must know what it is : a library for
accessing ssh client services through C libraries calls in a simple manner.
Everybody can use this software under the terms of the LGPL- see the COPYING

Linux 是一个源码开放的操作系统，无论是普通用户还是企业用户都可以编写自己的内核代码，再加上对标准内核的裁剪从而制作出适合自己的操作系统。目前有很多中低端用户使用的网络设备的操作系统是从标准 Linux 改进而来的，这也说明了有越来越多的人正在加入到 Linux 内核开发团体中。
一个或多个内核模块的实现并不能满足一般 Linux 系统软件的需要，因为内核的局限性太大，如不能在终端上打印，不能做大延时的处理等等。当我们需要做这些的时候，就需要将在内核态采集到的数据传送到用户态的一个或多个进程中进行处理。这样，内核态与用户空间进程通信的方法就显得尤为重要。在 Linux 的内核发行版本中没有对该类通信方法的详细介绍，也没有其他文章对此进行总结，所以本文将列举几种内核态与用户态进程通信的方法并详细分析它们的实现和适用环境。
