getwchar(3)                Library Functions Manual                getwchar(3)

NAME
       getwchar - read a wide character from standard input

LIBRARY
       Standard C library (libc, -lc)

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.

HISTORY
       C99, POSIX.1-2001.

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.
