Why do you "have to" use an Fd? A regular handle should be sufficient. Where do you get the Fd from?
createPipe :: IO (Fd,Fd) (Unkown alternatives)
I suppose you have to pass this descriptor to another process through fork()?
Did you consider lifting the Fd back to a Handle?
How ? Only known intToFd :: Int -> Fd fdToInt :: Fd -> Int
There's System.Posix.IO.fdToHandle :: Fd -> IO Handle
What about ? threadReadWait :: Int -> IO() Should I convert a Handle into a Int ?
Yes, that should work, too, but you won't know how many bytes are available. You could use or adapt one of the *MayBlock-ellipses from Foreign.C.Error together with threadWaitRead, but that's making things even more ugly.
