Wide-oriented streams contain a hidden multibyte
conversion state, equivalent to an mbstate_t, that helps
to transform between internal wide characters and external
multibyte characters. This state is also recorded in an
fpos_t.
It is an error to apply a byte-oriented function to a wide-oriented stream, or a wide-oriented function to a byte-oriented stream.
#include<stdio.h>#include<wchar.h>int fwide(FILE *stream, int mode);
An unoriented stream's orientation can be set with
fwide.
It attempts to make the stream wide-oriented if mode is positive, and byte-oriented if negative.
It does not attempt to change it if mode is zero. It returns the new orientation,
positive for wide-oriented, and negative for
byte-oriented.
