.Sh DESCRIPTION
|
|
The
|
|
.Fn fwide
|
|
function
|
|
determines the orientation of the stream pointed at by
|
|
.Fa stream .
|
|
.Pp
|
|
If the orientation of
|
|
.Fa stream
|
|
has already been determined,
|
|
.Fn fwide
|
|
leaves it unchanged.
|
|
Otherwise,
|
|
.Fn fwide
|
|
sets the orientation of
|
|
.Fa stream
|
|
according to
|
|
.Fa mode .
|
|
.Pp
|
|
If
|
|
.Fa mode
|
|
is less than zero,
|
|
.Fa stream
|
|
is set to byte-oriented.
|
|
If it is greater than zero,
|
|
.Fa stream
|
|
is set to wide-oriented.
|
|
Otherwise,
|
|
.Fa mode
|
|
is zero, and
|
|
.Fa stream
|
|
is unchanged.
|
|
.Sh RETURN VALUES
|
|
The
|
|
.Fn fwide
|
|
function
|
|
returns a value according to orientation after the call of
|
|
.Fn 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.
