Chapter 3

Writing a WDM driver is fundamentally an exercise in software engineering. Whatever the requirements of your particular hardware, you will combine various elements to form a program. In the previous chapter, I described the basic structure of a WDM driver, and I showed you two of its elements—DriverEntry and AddDevice—in detail. In this chapter, I'll focus on the even more basic topic of how you call upon the large body of kernel-mode support routines that the operating system exposes for your use. I'll discuss error handling, memory and data structure management, registry and file access, and a few other topics. I'll round out the chapter with a short discussion of the steps you can take to help debug your driver.
