fwide
— get/set
orientation of a stream
Standard C Library (libc, -lc)
#include <stdio.h>
#include <wchar.h>
int
fwide
(FILE
*stream, int
mode);
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.
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.
