NAME
getwchar - read a wide character from standard input
SYNOPSIS
#include <wchar.h>
wint_t getwchar(void);
DESCRIPTION
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).
RETURN VALUE
The
getwchar()
function returns the next wide-character from
standard input, or
WEOF.
ATTRIBUTES
For an explanation of the terms used in this section, see

CONFORMING TO

NOTES
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.
