title: Meaning of WinMain function call parameters?
body: <pre><code> int WINAPI WinMain(HINSTANCE hInstance, HINSTANCE hPrevInstance, PSTR pScmdline, int iCmdshow)
  </code></pre>
  
  <p>In this line, are these statements about the call parameters correct? </p>
  
  <p>HINSTANCE is a class and hInstance and hPrevInstance are objects, PSTR is a class and pScmdline is an object and int is a class and iCmdshow is an object ? </p>
