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.
