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 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.
RETURN VALUE
The getwchar function returns the next wide-character from
standard input, or WEOF.
CONFORMING TO
ISO/ANSI C, UNIX98
SEE ALSO
fgetwc(3)
NOTES
The behaviour 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.
