I cannot recommend Understanding and Using C Pointers by Richard Reese highly enough (http://www.amazon.com/Understanding-Using-Pointers-Richard-Reese/dp/1449344186 http://www.amazon.com/Understanding-Using-Pointers-Richard-R...) Learning C syntax is pretty easy. Learning to use the standard library is mostly a matter of reading man pages and other people's code. But I found understanding pointers and memory management completely opaque until I read that book. It definitely brought me from "beginning C hacker flailing about" to "intermediate C hacker flailing about in a more dangerous way".
