[Haskell-beginners] Fwd: Real World Haskell: From Portable to System.Win32

createFile is probably what I should be looking for. As a side note, I really think this is not a big deal. The portable code is a lot better. I wonder if that exercise was a pun on working with Haskell code just to step back into foul territory. And yes, extra careful on the parameters, or it may end up corrupting other files, launch the missiles and whatnot. One thing I noticed so far using Haskell, usually I have to spend more time thinking before hitting the keyboard. Yet the code is always elegant. Meanwhile, I've been taking a peek inside System.IO.HVFS from MissingH [1]. Looks nice. Thanks for the replies.

getFileTime :: HANDLE -> IO (FILETIME, FILETIME, FILETIME)

I suppose that means getFileTime takes a file handle (with type HANDLE) and returns an IO type with CreationTime LastAccessTime LastWriteTime [3].

The thing is I don't know how to get a HANDLE type. I understand I can get a file handle by opening it. I've been trying the following:

openFile :: FilePath -> IOMode -> IO Handle fh <- openFile "myfile.hs" ReadMode

Yes, the case is significant and that means that Handle and HANDLE aren't the same, apparently HANDLE is specific to the win32 api (which I don't know well), a rapid inspection of System.Win32.File seems to reveal that the only function to get an HANDLE is createFile which has a ton of parameters you'll need to set carefully to avoid overwriting your existing file (you should probably define another function with most of these already fixed for convenience) but should do the trick.
