putwchar(3) Library Functions Manual putwchar(3)
putwchar - write a wide character to standard output
Standard C library (libc, -lc)
#include <wchar.h>
wint_t putwchar(wchar_t wc);
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).
The putwchar() function returns wc if no error occurred, or WEOF
to indicate an error.
For an explanation of the terms used in this section, see
attributes(7).

C11, POSIX.1-2008.
POSIX.1-2001, C99.
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.
