PROLOG
       This  manual  page is part of the POSIX Programmer's Manual.  The Linux
       implementation of this interface may differ (consult the  corresponding
       Linux  manual page for details of Linux behavior), or the interface may
       not be implemented on Linux.
NAME
       getwc - get a wide character from a stream
SYNOPSIS
       #include <stdio.h>
       #include <wchar.h>
       wint_t getwc(FILE *stream);

DESCRIPTION
       The getwc() function shall be equivalent to fgetwc(), except that if it
       is implemented as a macro it may evaluate stream more than once, so the
       argument should never be an expression with side effects.
RETURN VALUE
       Refer to fgetwc().
ERRORS
       Refer to fgetwc().
       The following sections are informative.
EXAMPLES
       None.
APPLICATION USAGE
       Since it may be implemented as a macro, getwc() may treat incorrectly a
       stream  argument with side effects. In particular, getwc(*f++) does not
       necessarily work as expected.  Therefore, use of this function  is  not
       recommended; fgetwc() should be used instead.
RATIONALE
       None.
FUTURE DIRECTIONS
       None.
