getwchar

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

       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 char-
       acter.

SEE ALSO

       fgetwc(3), unlocked_stdio(3)

COLOPHON

       This page is part of release 3.27 of the Linux man-pages project.  A description of the project, and information about reporting bugs,  can
