Tring openBinaryFile,
Well, did you get it to work?
I can not locate which module including readBinaryFile.
This is what I find in System.IO (ghci> :b System.IO): openBinaryFile :: FilePath -> IOMode -> IO Handle openBinaryTempFile :: FilePath -> String -> IO (FilePath, Handle) hSetBinaryMode :: Handle -> Bool -> IO () so you have the option of either using openBinaryFile or openFile and using hSetBinaryMode to true. I guess - I've never had to use them. I can't find a readBinaryFile either, but writing one might be a good excercise? Makes me wonder whether one should have binary be the default? I'm a stranger in Windows-land, but are there cases where you want reading of a file to be terminated on ^Z? Seems pretty awful to me. Concerning mutable buffers, it is of course possible, but hardly idiomatic Haskell. Why do you need mutability? -k
