I would also add the chapter 17 of Real World Haskell. you can read it
It will guide you through the writing of the bindings to the PCRE
library. Very useful and nicely conceived.
A good collection of Storable instances that I found very helpful in
understanding the subject can be found in the X11 bindings.
Hope this helps,
