This structure defines the interface between the low-level tty driver and the tty routines. The following routines can be defined unless noted otherwise, they are optional, and can be filled in with a null pointer.-This structure defines the interfac

tty驱动 * This driver shows how to create a minimal tty driver. It does not rely on * any backing hardware, but creates a timer that emulates data being received * from some kind of hardware.- tty driver* This driver shows how to create a minimal tty d

本书是一本介绍Linux设备驱动开发理论、框架与实例的书，本书以Linux 2.6版本内核为蓝本，详细介绍自旋锁、信号量、完成量、中断顶/底半部、定时器、内存和I/O映射以及异步通知、阻塞I/O、非阻塞I/O等Linux 设备驱动理论；字符设备、块设备、TTY设备、I2C设备、LCD设备、音频设备、USB设备、网络设备、PCI设备等Linux设备驱动的架构和框架中各个复杂数据架构和函数的关系，并讲解了大量Linux驱动开发的大量实例，使读者能够独立开发各类Linux设备驱动。-This book
