<h2>Description</h2>
The class MountNotify is identical to Mount1 in nearly all aspects except:
<ul>
  <li>it publishes and consumes data from an event channel using the ACS event channel API.</li>
  <li>exception handling is not used.</li>
</ul>
<br>
<br>
<h2>What can I gain from this example?</h2>
<ul>
  <li>an example derived from the ACS::Component IDL interface.</li>
  <li>understanding of synchronous method implementation.</li>
  <li>publishing events (in the form of user-defined IDL structs) to consumers.</li>
  <li>processing events (in the form of user-defined IDL structs) sent by suppliers.</li>
</ul>
