GETWCHAR(3) Linux Programmer's Manual GETWCHAR(3)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 cur‐
rent locale.
It is reasonable to expect that getwchar() will actually read a multi‐
byte sequence from standard input and then convert it to a wide charac‐
ter.
