How to access *fcmp passed from parameter
<p>Currently I am working on a merge sort project in my class and am stuck on how to access and utilize the last parameter of this function header:</p>

<pre><code>void Mergesort(ItemType* item, size_t nelem, int **(*fcmp) (const ItemType&amp; e1, const ItemType&amp; e2))**
</code></pre>

<p>Knowing that the result of the comparison will be <em>-1</em>, <em>0</em>, or <em>1</em> but since the parameter itself doesn't have a name, I don't know how to explicitly call the pointer of the function.</p>

<p>Thanks in advance for any help.</p>
