wcrtomb -- convert a wide-character code to a character (restartable)
Standard C Library (libc, -lc)
wcrtomb(char * restrict s, wchar_t wc, mbstate_t * restrict ps);
The wcrtomb() function stores a multibyte sequence representing the wide
character wc, including any necessary shift sequences, to the character
array s, storing a maximum of MB_CUR_MAX bytes.
If s is NULL, wcrtomb() behaves as if s pointed to an internal buffer and
wc was a null wide character (L'\0').
The mbstate_t argument, ps, is used to keep track of the shift state. If
it is NULL, wcrtomb() uses an internal, static mbstate_t object.
The wcrtomb() functions returns the length (in bytes) of the multibyte
sequence needed to represent wc, or (size_t)-1 if wc is not a valid wide
The wcrtomb() function will fail if:
[EILSEQ] An invalid wide character code was specified.
mbrtowc(3), setlocale(3), wctomb(3)
The wcrtomb() function conforms to ISO/IEC 9899:1999 (``ISO C99'').
The current implementation does not support shift states.
