title: function pointer handling in Doxygen in C
body: <p>In my code, a vtable containts several function pointer.
  Doxygen is unable to follow them.</p>
  
  <p>I'd like to force it to recognize the possible paths, to produce a complete Call Graph, since now this part is missing.</p>
  
  <p>example:</p>
  
  <pre><code>typedef Bool(*SPECIAL_FUNC)(KEY key);
  
  typedef struct{
    int a;
    int b;
    SPECIAL_FUNC;
  }OBJ;
  
  Bool add(KEY key); //code...
  Bool sub(KEY key); //code...
  </code></pre>
