[Haskell-cafe] Exclusive mode in openFile

Hi all, It seems I'm not allowed to open same file both for writing and for reading: Prelude System.IO> f_out <- openFile "mylog.log" AppendMode Prelude System.IO> f_in <- openFile "mylog.log" ReadMode *** Exception: mylog.log: openFile: resource busy (file is locked) Usage scenario: I use hslogger to write to logs, but I'd like to read parts of these logs *from inside same Haskell application*. How do I get around exclusive mode in openFile? -- Gracjan
