title: Assertion.h in FreeBSD
body: <p>I am trying to change the kernel of the freebsd and I need to use the library <code>list.h</code> which is in the directory: <code>/usr/src/lib/libc/include/isc</code>. There are two lines in this file which make errors:</p>
  
  <pre><code>#include &lt;assert.h&gt;
  #include &lt;isc/assertion.h&gt;
  </code></pre>
  
  <p>I could find the file <code>assert.h</code> and put it in the directory but I couldn't find <code>assertion.h</code> file on the net. Is there any link for downloading this library?</p>
