title: Delphi function comparing content of two TStream?
body: <p>I need to compare if two <strong>TStream</strong> descendant <strong>have the same content</strong>.
  The only interesting result for me is the boolean Yes / No.</p>
  
  <p>I'm going to code a <strong>simple loop</strong> checking byte after byte the streams content's.</p>
  
  <p>But I'm <strong>curious</strong> to know if there is an already existing function. I haven't found any inside DelphiXE or JCL/JVCL libs.</p>
  
  <p>Of course, the two streams have the same size !</p>
