How to translate this line of code from C++ to Objective-C : <p>I need to translate this line from C++ to Objective-C
but I don't really understand this line</p>

<pre><code>IntVar* MakeIntVar(int64 vmin, int64 vmax, const std::string&amp; name);
</code></pre>

<p>This seems to be for me a function without a return value? </p>

<p>IntVar is by the way a class</p>

<pre><code>class IntVar;
</code></pre>
