fwide()

Set or get the stream orientation

Synopsis:

#include <wchar.h>

int fwide( FILE * fp,
           int mode  );

fp

The stream whose orientation you want to set.

mode

The orientation mode:

If mode is greater than zero and the stream orientation hasn't been set, fwide() flags the stream as wide-oriented.
If mode is less than zero, fwide() behaves similarly, but flags the stream as byte-oriented.
If mode is zero, fwide() returns the stream type without altering the stream.

libc

Use the -l c option to qcc to link against this library. This library is usually included automatically.

The fwide() function sets or determines the orientation of the stream fp.
