The MD5SUM.EXE file I have chokes if you ask it to hash a file in another directory. It will hash from stdin, or from a file in the current directory, but point-blank refuses to hash anything else. So I'd have to write my Haskell code to open the file I want and *pipe* it to stdin on MD5SUM.EXE (making sure to not translate line ends or anything else that will alter the hash code). Then I have to parse the output and change it to actually match the UNIX md5sum program. [Because I want to make it compatible with that.] That also involves some fun with line ends...
I'm drawing a blank on the windows API, but at least in DOS it was possible to redirect standard input from a file without involving your program. Stefan
