title: Assignment with two values in Linux kernel
body: <p>I'm preparing a presentation on the linux kernel file <a href="https://github.com/torvalds/linux/blob/master/kernel/module_signing.c" rel="nofollow">module_signing.c</a> and on line 193 there is something I really don't get.
  The line is:</p>
  
  <pre><code>    size_t modlen = *_modlen, sig_len;
  </code></pre>
  
  <p>How can you have two values on the right side of the assignment operator??</p>
  
  <p>Any help would be great. Thanks!</p>
