title: Printing various FILE info
body: <p>Are there various print formatters for the file object? For example:</p>
  <pre><code>// pass the filepath
  char * filepath = argv[1];
  FILE * file = fopen(filepath, &quot;r&quot;);
  printf(&quot;Filepath: %s\n&quot;, file.size);
  </code></pre>
  <p>Error message:</p>
  <pre><code>main4.c:416:32: error: no member named 'size' in 'struct __sFILE'
  </code></pre>
  <p>What are the various items that can be printed from the struct?</p>
