  protected: streambuf();
  protected: streambuf( char* pr, int nLength );
 
  Parameter   Description
 
  <pr>        A pointer to a previously allocated reserve area of length
              <nLength>. A NULL value indicates an unbuffered stream.
 
  <nLength>   The length (in bytes) of the reserve area. A length of 0
              indicates an unbuffered stream.
 
  Remarks
 
  The first constructor makes an uninitialized streambuf object. This
  object is not suitable for use until a setbuf call is made. A derived
  class constructor usually calls setbuf or uses the second constructor.
 
  The second constructor initializes the streambuf object with the
  specified reserve area or marks it as unbuffered.
