Query: Quick Look Encounters Errors and Typos

In the sections I have had to study, the book is obviously filled with typos. Sadly, it is another example of a poorly edited computer book. P.118 talks of a GetBothForks function. In the example, that function does not exist. There is a function called GetForks. That may be what they are referring to(?) On the next page the book discusses Preemption. The lines referenced in the example are obviously not the lines intended. In other words, references to lines 9-13 are probably really referencing lines 15 - 20(?) Finally, that solution is essentially the same as the previous. The first question a good student would ask is what is the difference? Of course, I guess the book does not pre-suppose a good student is reading. In summary, not edited well and therefore not trustworthy.
