title: List particular function calls in outline of eclipse
body: <p>In my C-code I repeatedly use a function from an external library:</p>
  <pre><code>XCALL(&quot;Blabla&quot;);
  ...
  XCALL_END(&quot;Blabla&quot;);
  </code></pre>
  <p>It would be very helpful to be able to put each XCALL call into the outline view for better code querying. However, I could not find an easy solution for this. Also, installed Xtext in hope it was easy to configure. Any ideas?</p>
  <p>Many thanks in advance!</p>
