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 *attributes*(7).

CONFORMING TO
POSIX.1-2001, POSIX.1-2008, C99.
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.
