005.Character Device Driver Development with Project
Abstract:
A character device driver is one that transfers data directly to and from a user process. This is the most common type of device driver and there are plenty of simple examples in the source tree. Character device drivers may transfer data between a user-level process and the device using any scheme other than the system buffer cache. Character drivers control devices such as network cards, terminal devices, printers, and specialized devices such as robots, medical devices, and retail sales devices.
