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


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

       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).

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

       Apart from the usual ones, there is

       EILSEQ Conversion of wc to the streams encoding fails.

       C99, POSIX.1-2001.

       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.
