WCTOMB(3)	       FreeBSD Library Functions Manual		     WCTOMB(3)

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

LIBRARY
     Standard C	Library	(libc, -lc)

SYNOPSIS
     #include <stdlib.h>

     int
     wctomb(char *mbchar, wchar_t wchar);

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

     A call with a null	mbchar 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.

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

ERRORS
     The wctomb() function will	fail if:

     [EILSEQ]		An invalid multibyte sequence was detected.

     [EINVAL]		The internal conversion	state is invalid.

SEE ALSO
     mbtowc(3),	wcrtomb(3), wcstombs(3), wctob(3)

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