title: wifi scan with ioctl SIOCGIWSCAN
body: <p>i wonder if anyone can tell me how to interpret the data that come as result from a wifi scan with</p>
  
  <pre><code>if (-1 != (status = ioctl(handle, SIOCGIWSCAN, &amp;data)))
  {
      data.u.data.pointer = ? what struct is this ?
  }
  </code></pre>
  
  <p>I t seems like a big char [] blob of data but there must be some kind of structure behind.</p>
  
  <p>Thank youe</p>
