getwchar — read a wide character from standard input
#include <wchar.h>
wint_t getwchar( |
void); |
The getwchar() function is
the wide-character equivalent of the getchar(3) function. It
reads a wide character from stdin and returns it. If the end of stream
is reached, or if ferror(stdin) becomes true,
it returns WEOF. If a
wide-character conversion error occurs, it sets errno to EILSEQ and returns WEOF.
For a non-locking counterpart, see unlocked_stdio(3).
The behavior of getwchar()
depends on the LC_CTYPE
category of the current locale.
It is reasonable to expect that getwchar() will actually read a multibyte
sequence from standard input and then convert it to a wide
character.
