putwchar - write a wide character to standard output
Návod, kniha: Linux Programmer's Manual
#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.
For a non-locking counterpart, see
unlocked_stdio(3).
The
putwchar function returns
wc if no error occurred, or WEOF to
indicate an error.
ISO/ANSI C, UNIX98
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.
