title: Interpreting strace output
body: <p>With strace it is possible to see the ioctl call for the certain file descriptor and with certain command. The third argument is a structure, but strace shows it as a raw pointer to the memory. 
  strace output example:</p>
  
  <pre><code>open("/dev/node", O_RDWR) = 3
  ioctl(3, 0x108, 0x8f0eb18) = 0
  close(3)  
  </code></pre>
  
  <p>Is there a way (strace options or other tools) to see what is the structure, or at least a value behind a raw pointer?</p>
