i am not sure i understand what you are saying correctly, but if you
think you can get long file names on a system that does not support them
(such as dos 6.22/win 3.1x) by adjusting a macro definition, you are
mistaken. consult the faq regarding details on lfn.

you need to use fflush to commit buffers to disk. do read the
documentation, the C and C++ faqs and consider getting an introductory C
book.
