FFI package bindings-DSL provides a language to describe foreign
interfaces on top of hsc2hs.

New to this release is that you can get pointers to all declared fields
of a structure. Suppose you have the following struct in C:
struct a {
int b;
struct {
char c;
float d;
} e;
struct a *f;
};
You write this in your .hsc file:
#starttype struct a
#field b , CInt
#field e.c , CChar
#field e.d , CFloat
#field f , Ptr <a>
#stoptype
Besides the usual Storable instantiated Haskell version of struct a,
(named C'a), now you also get the following:
p'a'b :: Ptr C'a -> Ptr CInt
p'a'e'c :: Ptr C'a -> Ptr CChar
p'a'e'd :: Ptr C'a -> Ptr CFloat
p'a'f :: Ptr C'a -> Ptr (Ptr C'a)
Hope it's useful to you.
Best,
Maurício
