Just because you're working in C doesn't mean you need to handle every detail yourself. In fact, please don't handle every detail yourself. Show your readers how to use some of the great libraries C has to offer. Not just system-level abstraction layers, either. You need to go get libraries for a lot of the stuff you'd normally use the standard library for in a more modern language. These libraries exist, and many of them are excellent, but because they're not built-in, people are less likely to use them. This is especially dangerous in C, because it requires so much work to do anything even vaguely complex. edit: That came off as saying "Teach some libraries". What I really mean is "Teach people to go find libraries."
