Linux环境下模拟鼠标操作

在Linux/input.h中定义了以下结构体类型，用于标准按键的编码操作：

Struct input_evnet{

Struct timeval time; //按键时间

_u16 type;//类型

_u16 code;//模拟成什么按键码

_u32 value;//按下还是释放

}

Type:

EV_KEY:表示键盘；EV_REL表示相对坐标；EV_ABS表示绝对坐标

Code:

若事件类型为EV_KEY,code为按键的键值码，vaule为0表示释放，value为1表示按下；若事件类型为EV_REL,code为REL_X(表示鼠标的X轴方向)或者REL_Y(表示鼠标的Y轴方向)。
