当输入设备有事件产生时,内核就会将事件上报到设备文件,事件的数据以struct input_event为单位存入设备文件,所以读取事件数据时使用struct input_event结构体,这个结构体定义在/usr/include/linux/input.h中,定义如下: struct input_event {struct timeval time;__u16 type;__u16 code;__s32 value;}; 二、结构体...

This field denotes the total size of the event as stored in memory. This includes the full size of this struct and not just the "payload" of the event. // Store event in private buffer: unsafe byte[] CopyEventData(InputEventPtr eventPtr) { var sizeInBytes = eventPtr.sizeInBytes; var...
Linux系统struct input_event结构体分类型(鼠标、键盘、触屏)详解与例子 一、概述Linux系统是通过输入子系统来管理输入设备(如鼠标、键盘、触摸屏、游戏摇杆)的。配置了内核支持且安装对应驱动后,当系统接入输入设备,会在/dev/input下生成对应设备文件,下图是鼠标、键盘在不同情况下/dev/input的设备文件。当输入设备有...
