title: dereferencing a created pointer
body: <p>I just have a quick question about what this code mean. Sorry, been reading other posts but I couldn't fully grasp the concept since none seems to resemble this piece of code that I'm currently working in my embedded system.</p>
  
  <pre><code>int8u buf[1024];
  memset(buf, 0, sizeof(buf));
  *((int16u*)&amp;buf[2]) = 0xbb01;
  </code></pre>
  
  <p>can someone explain to me what these lines mean?</p>
