/***
*size_t wcstombs() - Convert wcs to mbcs
*
*Purpose:
* Convert a wide char string into the equivalent multibyte char string,
* according to the LC_CTYPE category of the current locale.
* [ANSI].
*
* NOTE: Currently, the C libraries support the "C" locale only.
*Entry:
* char *s = pointer to destination multibyte char string
* const wchar_t *pwc = pointer to source wide character string
* size_t n = maximum number of bytes to store in s
*
*Exit:
* If s != NULL, returns (size_t)-1 (if character cannot be converted)
* or number of bytes comprising the converted
* mb string, not including any terminating NUL.
*
*Exceptions:
* Returns (size_t)-1 if pwcs is NULL or a character cannot be converted
*

    Very nice! Thank you for this wonderful archive. I wonder why I found it only now. Long live the BBS file archives!

    This is so awesome! 😀 I’d be cool if you could download an entire archive of this at once, though.

    But one thing that puzzles me is the “mtswslnkmcjklsdlsbdmMICROSOFT” string. There is an article about it here. It is definitely worth a read: http://www.os2museum.com/wp/mtswslnk/
