title: Pointer to data that stored in a map container
body: <p>I have 2 map one of them contain data</p>
  
  <p>for example </p>
  
  <pre><code>struct DATA {
    int A1;
    int A2;
  };
  typedef map&lt;int,DATA&gt; DataList;
  DataList myData;
  </code></pre>
  
  <p>I have also tried some of the following: 
        <code>typedef  map&lt;int,DATA*??&gt; DataListPointer;</code> 
        <code>table&lt;col_name,DataListPointer&gt;;</code></p>
  
  <p>(Note: CC: I really do not get this line:</p>
  
  <blockquote>
    <p>map is a table. list of  column and pointer to data that exist on <code>myData</code>.</p>
  </blockquote>
  
  <p>or what table is doing in the above
  ).</p>
  
  <p>but i would like to know how to get to a pointer to data that exist in a map. How I can do it?
  thanks herzl.</p>
