[Haskell-cafe] hPutStrLn and hFlush

Hi all, A bit strange behaviour with hPutStrLn. Consider following program: main = do handle <- openFile "output.txt" WriteMode hPutStrLn handle (unlines contLines2) -- hFlush houtput where contLines2 = flip map [1..2000] $ \x -> show x ++ " been there done that" Outputs file which ends with following lines: 1989 been there done that 1990 been there done that 1991 been there done that 1992 been there done that 199 (END) So the output is truncated. When I uncomment hFlush, file is fully written. Is this expected/documented behaviour? Platform: WinXP, GHC version 6.4.1 -- Regards, Gracjan
