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
       attributes(7).

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

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.
