getwchar(3)             Library Functions Manual             getwchar(3)

NAME         top

       getwchar - read a wide character from standard input

LIBRARY         top

       Standard C library (libc, -lc)

SYNOPSIS         top

       #include <wchar.h>

       wint_t getwchar(void);

DESCRIPTION         top

       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         top

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

HISTORY         top

       C99, POSIX.1-2001.

NOTES         top

       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.
