PUTWCHAR (3)
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 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.
RETURN VALUE
The putwchar function returns wc if no error occurred, or WEOF to
indicate an error.

SEE ALSO
NOTES
The behaviour 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.
