putwc

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  fer-
       ror(stream) becomes true, it returns WEOF.  If a wide-character conver-
       sion 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 non-locking counterparts, see unlocked_stdio(3).

RETURN VALUE
       The fputwc() function returns wc if no error occurred, or WEOF to indi-
       cate an error.

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  cur-
       rent locale.

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