NAME    [Toc]    [Back]

     wcrtomb -- convert a wide-character code to a character (restartable)

LIBRARY    [Toc]    [Back]

     Standard C Library (libc, -lc)

SYNOPSIS    [Toc]    [Back]

     #include <wchar.h>

     size_t
     wcrtomb(char * restrict s, wchar_t wc, mbstate_t * restrict ps);

DESCRIPTION    [Toc]    [Back]

     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.

RETURN VALUES    [Toc]    [Back]

     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
     character code.

ERRORS    [Toc]    [Back]

     The wcrtomb() function will fail if:

     [EILSEQ]		An invalid wide character code was specified.

SEE ALSO    [Toc]    [Back]

     mbrtowc(3), setlocale(3), wctomb(3)

STANDARDS    [Toc]    [Back]

     The wcrtomb() function conforms to ISO/IEC 9899:1999 (``ISO C99'').

BUGS    [Toc]    [Back]

     The current implementation does not support shift states.
