I don't mind having these functions, but to be honest I doubt that they would be useful for real life applications. Reading a byte at a time is a performance nightmare, buffering or not. IMHO, the much better API is this one:
hPutBufNonBlocking :: Handle -> Ptr a -> Int -> IO Int hGetBufNonBlocking :: Handle -> Ptr a -> Int -> IO Int
You have these in GHC.IO at the moment. I beieve they don't have proper non-blocking behaviour on Windows, though. These are also rather more difficult to implement than the single-byte versions, so I can't see nhc98 or Hugs implementing them any time soon. Cheers, Simon
