Re: FW: [ma-linux] Info about top command required

Hi mark ,

Thanks for the info.

But the question really is , whether SIZE corrosponds to

  real memory( real text + real data + real stack)
                              OR
  virtual  memory(virtual text + virtual data + virtual stack)
                              OR
   both????

Thanks
Milind
