NAME

       fputwc - 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 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 non-locking counterparts, see unlocked_stdio(3).

RETURN VALUE

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

ERRORS

       Apart from the usual ones, there is

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

CONFORMING TO

       ISO/ANSI C, UNIX98

NOTES

       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.

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 fer-
       ror(stream) becomes true, it returns WEOF.  If a wide-character conversion error occurs, it sets errno to EILSEQ and returns WEOF.   Other-
       wise 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.

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.
