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.
