I've a windows application that calls the win32 API function FindFirstFileA on a non-existent file. 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. Under windows, the function doesn't return INVALID_HANDLE_VALUE, even if the file doesn't exist. On the contrary, with wine under linux it successfully returns INVALID_HANDLE_VALUE. Does anyone have an interpretation for this strange difference between the behaviour of this function with windows(the one with the strange behaviour) versus wine under linux?
