I bought this book on Yegge's recommendation as well, and this actually was a stumbling block for me at first. "Whyyy is this variable, ★★p a pointer to a pointer?! p is never referenced in the function, so why are we two levels of indirection down?!" I didn't realize at the time that pointers are copied by value in C, so in order to modify the pointer you need to give the function a pointer to it. I guess it was worthwhile, though, because it encouraged me to play around with C[1] a bit in order to grok it. P.S. Sorry for those stupid stars, HN kept eating my highlights. Any way to avoid that?
