  -- | Read data from an 'Fd' into memory.  This is exactly equivalent
  -- to the POSIX @read@ function.
  fdReadBuf :: Fd
            -> Ptr Word8    -- ^ Memory in which to put the data
            -> ByteCount    -- ^ Maximum number of bytes to read
            -> IO Bytecount -- ^ Number of bytes read (zero for EOF)
  
  -- | Write data from memory to an 'Fd'.  This is exactly equivalent
  -- to the POSIX @write@ function.
  fdWriteBuf :: Fd
             -> Ptr Word8    -- ^ Memory containing the data to write
             -> ByteCount    -- ^ Maximum number of bytes to write
             -> IO ByteCount -- ^ Number of bytes written
