!= operator and file streams
<pre><code>#include &lt;iostream&gt;
#include &lt;fstream&gt;

using namespace std;

int main()
{

    ifstream file0( "file0.txt" );
    ifstream file1( "file1.txt" );

    if (file0 != file1) {
        cout &lt;&lt; "What is being compared?" &lt;&lt; endl;
    }

} 
</code></pre>

<p>If the above code, what is being compared in the conditional? I believe it is pointer values but I am unable to find supporting evidence.</p>

<p>Thanks!</p>
