putwchar - write a wide character to standard output
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 con
version error occurs, it sets errno to EILSEQ and returns WEOF. Other
wise it returns wc.
For a non-locking counterpart, see unlocked_stdio(3).
The putwchar() function returns wc if no error occurred, or WEOF to
indicate an error.
The behavior of putwchar() depends on the LC_CTYPE category of the cur
It is reasonable to expect that putwchar() will actually write the
multibyte sequence corresponding to the wide character wc.
