FWIDE(3)                   BSD Programmer's Manual                    FWIDE(3)

NAME

     fwide - get/set orientation of a stream

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 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

     fwide() 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.

STANDARDS

     The fwide() function conforms to ISO/IEC 9899:1999 ("ISO C99").
