  protected: void unbuffered( int nState );
  protected: int unbuffered() const;
 
  Parameter   Description
 
  <nState>    The value of the buffering state variable; 0 = buffered,
              nonzero = unbuffered.
 
  Remarks
 
  The first overloaded unbuffered function sets the value of the streambuf
  object's buffering state. This variable's primary purpose is to control
  whether the allocate function automatically allocates a reserve area.
 
  The second function returns the current buffering state variable.
