Chapter 17. Input Devices Drivers
Input devices are devices with which you can interact with the system. Such devices include buttons, keyboards, touchscreens, the mouse, and so on. They work by sending events that are caught and broadcast over the system by the input core. This chapter will explain each structure used by the input core to handle input devices. We will also illustrate how you can manage events from the user space.
In this chapter, we will cover the following topics:
- Inputting core data structures
- Allocating and registering input devices, as well as the polled device family
- Generating and reporting events to the input core
- Inputting devices from user space
- Writing a driver example
