putwchar - write a wide character to standard output

#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.
