getwchar - read a wide character from standard input
Standard C library (
libc,
-lc)
#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 nonlocking counterpart, see
unlocked_stdio(3).
The
getwchar() function returns the next wide-character from standard
input, or
WEOF.
For an explanation of the terms used in this section, see

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.
