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.

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.
