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
according 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.
