<p>Hi, <br>
</p>
<p>I am trying to modify the example "consumer-with-timer" in
ndn-cxx to be able to set a parameter name on the delayInterest
method so it will look like delayedInterest(const Name& name)</p>
<p>When trying to schedule a new event using this code:</p>
<p> m_scheduler.scheduleEvent(time::seconds(10),<br>
bind(&ConsumerWithTimer::delayedInterest, ref(name)));<br>
</p>
<p>I get this compilation error: <br>
</p>

</p>
<p>Any idea? <br>
</p>
<p>How can I schedule an event using methods with parameters? <br>
</p>
<p>Thanks</p>
