fwide(3C)                                                         fwide(3C)

NAME
     fwide - wide-character stream orientation

SYNOPSIS
     #include <stdio.h>
     #include <wchar.h>

     int fwide(FILE *stream, int mode);

DESCRIPTION
     The fwide() function determines the orientation of the stream pointed
     to by stream. If mode is greater than zero, the function first
     attempts to make the stream wide oriented. If mode is less than zero,
     the function first attempts to make the stream byte oriented. (If the
     orientation of the stream has already been determined, fwide() does
     not change it.) Otherwise, mode is zero and the function does not
     alter the orientation of the stream.

RETURN VALUES
     The fwide() function returns a value greater than zero if, after the
     call, the stream has wide orientation, a value less than zero if the
     stream has byte orientation, or zero if the stream has no orientation.
