The FFI spec is a wonderful document, but is of limited use in  
learning to use the FFI for practical tasks. I suggest you look into  
c2hs or some other tool that tries to help you with marshalling data  
structures (as compared to providing mechanisms sufficient for doing  

I suggest you do this even if you don't end up using a tool, as the  
generated Haskell has some carefully designed idioms that will  
definitely help.
