NAME

6       getwchar - read a wide character from standard input
7

SYNOPSIS

9       #include <wchar.h>
10
11       wint_t getwchar(void);
12

DESCRIPTION

14       The  getwchar()  function  is  the  wide-character  equivalent  of  the
15       getchar(3) function.  It reads a wide character from stdin and  returns
16       it.  If the end of stream is reached, or if ferror(stdin) becomes true,
17       it returns WEOF.  If a wide-character conversion error occurs, it  sets
18       errno to EILSEQ and returns WEOF.
19
20       For a nonlocking counterpart, see unlocked_stdio(3).
21

RETURN VALUE

23       The  getwchar()  function returns the next wide-character from standard
24       input, or WEOF.

NOTES

40       The behavior of getwchar() depends on the LC_CTYPE category of the cur‐
41       rent locale.
42
43       It is reasonable to expect that getwchar() will actually read a  multi‐
44       byte sequence from standard input and then convert it to a wide charac‐
45       ter.
