Just a thought, what about the other Simon's BlockIO library, its certainly very efficient, and probably what I am going to use for binaryIO from now on.

I've been playing around with decoding binary files, and I couldn't find a function in the libraries to read a byte from a file. Does anyone know if there is such a function? ....... it seems that we should have: hGetByte :: Handle -> IO Word8
hGetByte could be implemented on top of hGetBuf and StorableArray, but the overhead would be ugly. Recently I needed binary input for similar reasons, and would have used hGetByte had it been available. I ended up performing input using a reasonable-sized buffer.
In GHC, you can assume that hGetByte h = do c <- hGetChar h; return (fromIntegral (ord c))
you must open the file in binary mode (openBinaryFile). I don't think this works with Hugs, though.
Personally, I think this ought to be part of the redesign of the I/O library. hGetByte and hPutByte would be a stopgap. But, not much progress is being made on an I/O redesign right now.
