NAME    [Toc]    [Back]

       fputwc - write a wide character to a FILE stream

SYNOPSIS    [Toc]    [Back]

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

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

DESCRIPTION    [Toc]    [Back]

       The fputwc function is the wide-character equivalent of the fputc 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.

RETURN VALUE    [Toc]    [Back]

       The  fputwc  function returns wc if no error occurred, or WEOF to indicate
 an error.

ERRORS    [Toc]    [Back]

       Apart from the usual ones, there is

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

NOTES    [Toc]    [Back]

       The behaviour of fputwc depends on the LC_CTYPE category of the current
       locale.

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