/*************************************************************************                      Linux 模拟 鼠标 键盘 事件* 说明：*     以前看到有些软件能够控制鼠标移动，键盘操作等功能，总想知道这些到底* 是怎么做到的，好像是2年前也尝试去做这件事，但那时候对知识的匮乏直接导致* 无法进行，早上突然想到这件事，于是又搜索了一下，鉴于目前经常接触Linux* 驱动，对这些东西的理解也就很容易。**                                     2016-2-27 深圳 南山平山村 曾剑锋***********************************************************************/一、参考文章：1. 交互系统的构建之（二）Linux下鼠标和键盘的模拟控制http://blog.csdn.net/zouxy09/article/details/7920253
