title: 'class' keyword in function signature - is it standard C++?
body: <p>I'm studying code given to me and I see:</p>
  
  <pre><code>AFPSGameMode::AFPSGameMode(const class FPostConstructInitializeProperties&amp; PCIP)
      : Super(PCIP) {   }
  </code></pre>
  
  <p>I'm specially curious about the use of the <code>class</code> keyword. Is this standard C++ and if so what does it mean?</p>
  
  <p>Thank you.  </p>
