#include <wchar.h> wint_t putwchar(wchar_t wc);
DESCRIPTIONThe 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 VALUEThe putwchar() function returns wc if no error occurred, or WEOF to indicate an error.
ATTRIBUTESFor an explanation of the terms used in this section, see attributes(7).
CONFORMING TOPOSIX.1-2001, POSIX.1-2008, C99.
NOTESThe behavior of putwchar() depends on the LC_CTYPE category of the current locale.
