I´m Carol, and I´m just need some help to find the predefined types from the storable class. [...]

The following types are instances of Storable: Bool, Char, Int, Word, Ptr a, FunPtr a, StablePtr a, Float, Double, Word8, Word 16, Word32, Word64, Int8, Int16, Int32, Int64, Addr Note that the FFI "looks through" newtypes, so e.g. everything from CTypes is an instance of Storable, too. Did you have a look at the FFI draft http://www.cse.unsw.edu.au/~chak/haskell/ffi.ps.gz especially sec. 5.7? If yes, we should clarify this a bit... Hope that helps, S.
