How to pass a data structure between Haskell and other language? (for example C ?)

[Nguyen Phan Dung]

Hello,

I want to pass some data structure (such as a record ... ) between Haskell
and C.
If you know anybody who did this or you have any ideas about this, would you
please advise me?

Thank you very much !
