fwide(3)                 BSD Library Functions Manual                 fwide(3)


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 accord-
     ing 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.
