Chapter 2. Building and Running Modules
It's almost time to begin programming. This chapter
introduces all the essential concepts about modules and kernel
programming. In these few pages, we build and run a complete (if
relatively useless) module, and look at some of the basic code shared
by all modules. Developing such expertise is an essential foundation
for any kind of modularized driver. To avoid throwing in too many
concepts at once, this chapter talks only about modules, without
referring to any specific device class.All the kernel items (functions, variables, header files, and macros)
that are introduced here are described in a reference section at the
end of the chapter. |
