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
   ferror(stdout)  becomes  true,  it  returns  WEOF.  If a wide character
   conversion error occurs, it sets errno  to  EILSEQ  and  returns  WEOF.
   Otherwise, 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.

ATTRIBUTES

   For  an  explanation  of  the  terms  used   in   this   section,   see
   attributes(7).

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.
