LINUX-driver-interface-programming

代码说明：

  Linux系统中，设备驱动程序是操作系统内核的重要组成部分，在与硬件设备之间建立了标准的抽象接口。通过这个接口，用户可以像处理普通文件一样，对硬件设备进行打开(open)、关闭(close)、读写(read/write)等操作。通过学习和分析设备驱动程序，更深入理解Linux系统设备驱动开发。(Linux system, device drivers are an important part of the operating system kernel, and a standard abstract interface with hardware devices. Through this interface, users can to deal with ordinary file open (open), turn off the hardware (close), read and write (read/write) operation. Through study and analysis of device drivers, a deeper understanding of the Linux system, device driver development.)
