fwide(3) BSD Library Functions Manual fwide(3)
NAME
fwide -- get/set orientation of a stream
LIBRARY
Standard C Library (libc, -lc)
SYNOPSIS
#include <stdio.h>
#include <wchar.h>
int
fwide(FILE *stream, int mode);
DESCRIPTION
The fwide() function determines the orientation of the stream pointed at
by stream.
If the orientation of stream has already been determined, fwide() leaves
it unchanged. Otherwise, fwide() sets the orientation of stream accord-
ing to mode.
If mode is less than zero, stream is set to be byte-oriented. If mode is
greater than zero, stream is set to be wide-oriented. Otherwise, mode is
zero, and stream is unchanged.
RETURN VALUES
The fwide() function returns a value according to orientation after the
call of fwide(); a value less than zero if byte-oriented, a value greater
than zero if wide-oriented, and zero if the stream has no orientation.
