Foreign C with pointers

I am creating a binding to an existing library (lib*.a) from Haskell.
How can i bind a function that get a pointer?
e.g: I have in the c library.
int GetData( Data * d );
The steps that i need are:
1 - create the Data in Haskell
2 - create the foreign import sentence in a lib*.hs
3 - use the Data after the call
Where can i get a good tutorial about FFI? I try
http://www.haskell.org/hdirect/ffi.html but it's too general (need i pair of
examples, i think)
Thanks a lot, Luis Cabellos
