NAME

       fputwc, putwc - write a wide character to a FILE stream

SYNOPSIS

       #include <stdio.h>
       #include <wchar.h>

       wint_t fputwc(wchar_t wc, FILE *stream);
       wint_t putwc(wchar_t wc, FILE *stream);

DESCRIPTION

       The  fputwc()  function  is  the  wide-character  equivalent of the fputc(3) function.  It
       writes the wide character wc to stream.  If ferror(stream) becomes true, it returns  WEOF.
       If  a  wide-character  conversion  error occurs, it sets errno to EILSEQ and returns WEOF.
       Otherwise it returns wc.

       The putwc() function or macro functions identically to fputwc().  It may be implemented as
       a macro, and may evaluate its argument more than once.  There is no reason ever to use it.

       For nonlocking counterparts, see unlocked_stdio(3).

RETURN VALUE

       The  fputwc()  function returns wc if no error occurred, or WEOF to indicate an error.  In
       the event of an error, errno is set to indicate the cause.

ERRORS

       Apart from the usual ones, there is

       EILSEQ Conversion of wc to the stream's encoding fails.

CONFORMING TO

       C99, POSIX.1-2001.

NOTES

       The behavior of fputwc() depends on the LC_CTYPE category of the current locale.

       In the absence of additional information passed to the fopen(3) call, it is reasonable  to
       expect  that fputwc() will actually write the multibyte sequence corresponding to the wide
       character wc.
