As stated in microsoft windows SDK documentation at http://msdn.microsoft.com/en-us/library/aa364418(VS.85).aspx, the function should return INVALID_HANDLE_VALUE, which is equivalent to 0xFFFFFFFF, when the file interrogated doesn't exist. According to Wine tests this is correct. MSK61 wrote: > Under windows, the function doesn't return INVALID_HANDLE_VALUE, even if the file doesn't exist. Show some prove. Wine has extensive tests for this and these tests succeed on _all_ versions of windows. And Wine itself. Check your code.
