NAME
     wctomb, wctomb_l -- convert a wide-character code to a character

LIBRARY
     Standard C Library (libc, -lc)

SYNOPSIS
     #include <stdlib.h>

     int
     wctomb(char *s, wchar_t wchar);

     #include <stdlib.h>
     #include <xlocale.h>

     int
     wctomb_l(char *s, wchar_t wchar, locale_t loc);

DESCRIPTION
     The wctomb() function converts a wide character, wchar, into a multibyte character and stores the result in s.  The object pointed to by s
     must be large enough to accommodate the multibyte character, which may be up to MB_LEN_MAX bytes.

     A call with a null s pointer returns nonzero if the current locale requires shift states, zero otherwise; if shift states are required, the
     shift state is reset to the initial state.

     Although the wctomb() function uses the current locale, the wctomb_l() function may be passed a locale directly. See xlocale(3) for more
     information.

RETURN VALUES
     If s is NULL, the wctomb() function returns nonzero if shift states are supported, zero otherwise.  If s is valid, wctomb() returns the num-
     ber of bytes processed in s, or -1 if no multibyte character could be recognized or converted.  In this case, wctomb()'s internal conversion
     state is undefined.

ERRORS
     The wctomb() function will fail if:

     [EILSEQ]		An invalid multibyte sequence was detected.

     [EINVAL]		The internal conversion state is invalid.

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