-/* Stat by handle
- * Windows' stat() does not accept path which is added "\\?\" especially "?"
- * character.
- * It means we cannot access a long name path(which is longer than MAX_PATH).
- * So I've implemented simular Windows' stat() to access the long name path.
- * And I've added some feature.
- * 1. set st_ino by nFileIndexHigh and nFileIndexLow of
- *    BY_HANDLE_FILE_INFORMATION.
- * 2. set st_nlink by nNumberOfLinks of BY_HANDLE_FILE_INFORMATION.
- * 3. set st_dev by dwVolumeSerialNumber by BY_HANDLE_FILE_INFORMATION.
