<div>Hi is their a simple way <strong>at compile time </strong>to determine if a member function exist for a particular instance, if yes than use that function otherwise do not use it. <br><br>example std::list&lt;int&gt; li;
<br>// check if unique is a member function of li, if yes use unique. <br>li.unique();</div>
<div>// else use stl unique. </div>
<div>std::unique(li.begin(), li.end());</div>
