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

CONFORMING TO

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.
