PUTWCHAR(3)                                                  Linux Programmer's Manual                                                 PUTWCHAR(3)

NAME

       putwchar - write a wide character to standard output

SYNOPSIS

       #include <wchar.h>

       wint_t putwchar(wchar_t wc);

DESCRIPTION

       The  putwchar()  function is the wide-character equivalent of the putchar(3) function.  It writes the wide character wc to stdout.  If fer-
       ror(stdout) 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.

       For a nonlocking counterpart, see unlocked_stdio(3).

RETURN VALUE

       The putwchar() function returns wc if no error occurred, or WEOF to indicate an error.

CONFORMING TO

       POSIX.1-2001, POSIX.1-2008, C99.

NOTES

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

       It is reasonable to expect that putwchar() 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.  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

       POSIX.1-2001, POSIX.1-2008, C99.

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.
