       size_t mbrtowc(wchar_t *restrict pwc, const char s[restrict .n],
                      size_t n, mbstate_t *restrict ps);

<?><?><?><?><?><?><?><?>
       The main case for this function is when s is not NULL and pwc is not
       NULL.  In this case, the mbrtowc()  function inspects at most n bytes
       of the multibyte string starting at s, extracts the next complete
       multibyte character, converts it to a wide character and stores it at
       *pwc.  It updates the shift state *ps.  If the converted wide character
       is not L'\0' (the null wide character), it returns the number of bytes
       that were consumed from s.  If the converted wide character is L'\0',
       it resets the shift state *ps to the initial state and returns 0.

       The mbrtowc()  function returns the number of bytes parsed from the
       multibyte sequence starting at s, if a non-L'\0' wide character was
       recognized.  It returns 0, if a L'\0' wide character was recognized.
       It returns (size_t) -1 and sets errno to EILSEQ, if an invalid
       multibyte sequence was encountered.  It returns (size_t) -2 if it
       couldn't parse a complete multibyte character, meaning that n should be
       increased.
