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.
For an explanation of the terms used in this section, see attributes(7).
