FFI tutorial??

[Ronald Legere]

Does anyone know of a tutorial introduction to the
FFI? How does one go about getting started with this
thing? Any simple examples? I just want to be able
to do simple things (mostly access a c library from
haskell... ok maybe not trivial :) )  I would be
happy if I could just call c programs with simple
types and pointers (no way am I going to figure out 
struct alignment! ). 
   I have had some success with Java Native methods, 
so I believe such things can be done :0

Cheers!
