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.

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.
