fwide -- get/set orientation of a stream
Standard C Library (libc, -lc)
fwide(FILE *stream, int mode);
The fwide() function determines the orientation of the stream pointed at
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.
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.
