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
     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").
