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 non-locking counterpart, see unlocked_stdio(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
.
