NAME    [Toc]    [Back]

     fwide -- get/set orientation of a stream

LIBRARY    [Toc]    [Back]

     Standard C Library (libc, -lc)

SYNOPSIS    [Toc]    [Back]

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

     int
     fwide(FILE *stream, int mode);

DESCRIPTION    [Toc]    [Back]

     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 byte-oriented.  If it is
     greater than zero, stream is set to wide-oriented.  Otherwise, mode is
     zero, and stream is unchanged.

RETURN VALUES    [Toc]    [Back]

     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.
