title: How to convert sin_addr.S_un into char *?
body: <p>I need to get an IP address from a sender after he sent something to me. I'm using UDP socket, so the IP address of the sender will be automatically registered into <code>sin_addr</code> structure since I'm using <code>recvfrom()</code> function.</p>
  
  <p>How do I manipulate the <code>sin_addr</code> structure and convert it into a <code>char *</code>?</p>
  
  <p>Thank you.</p>
