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 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. |
The putwchar function returns wc if no error occurred, or WEOF to indicate an error. |

fputwc(3) |
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. |
