let's just test Alex small test program on various platforms and see what gives...You're missing my point (or maybe you're not and you just don't agree with me - in either case, let me make my point in a clearer way). If windows doesn't say it won't change the last error, we, as programmers, should assume that it might. In my experience, a large number of functions that set last error on failure set it to ERROR_SUCCESS on success. For the few that don't, I would consider this an oversight on MS's part, and I wouldn't expect it to exist in all implementations of a particular function (across OS versions).
