getwchar3
Read a wide character from standard input
Usage
#include <wchar.h>
wint_t getwchar(void);
Library
Standard C library (libc, -lc)
Overview
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.

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.
