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.

CONFORMING TO

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

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.
