Well, after my carefully investigations of << and >>
, I bielive it is not so trivail in C++ to control.

For example, I have to set up bufers for a 
data compressed encoder and decoder of various comprssion methods with options for fast speed RW operations or smaller sizes in the heap or the swap
files in the hd. 

How do I pass the option?

Unless I design a control foarmt for the stream 
or use some external methods to pass the  options
to the stream operators, I can't think of better ways
in C++ stream operator reloading.

I am wondering is there other way for the >> and <<
operator reloadings.
