In unix-2.7.0.0, fdRead and fdWrite in System.Posix.IO.ByteString use String instead of ByteString. This is wrong, isn't it? The point of the .ByteString modules is to do IO in ByteString.
Fwiw, here's the commit introducing the ByteString API and stating its intention: http://git.haskell.org/packages/unix.git/commitdiff/34c7bf896f19b182cf6fa104... However, I'm not totally sure from that, whether the type-sigs fdRead :: Fd -> ByteCount -- ^How many bytes to read -> IO (String, ByteCount) -- ^ The bytes read, how many bytes were read. fdWrite :: Fd -> String -> IO ByteCount were really intended to be that way. Simon, maybe you can provide some insight here? Cheers, hvr
