[Haskell-cafe] Writing binary files

Hi, I'm trying to write out a binary file, in particular I want the following functions: hPutInt :: Handle -> Int -> IO () hGetInt :: Handle -> IO Int For the purposes of these functions, Int = 32 bits, and its got to roundtrip - Put then Get must be the same. How would I do this? I see Ptr, Storable and other things, but nothing which seems directly useable for me. Thanks Neil
