title: Get only closed questions from the Stack Exchange api, via /questions?
body: <p>I want to get only closed questions from <code>/questions</code> of the Stack Exchange API.</p>
  
  <p>I've played around a bit with the filters, and I've come up with <a href="https://api.stackexchange.com/docs/questions#order=desc&amp;sort=activity&amp;filter=!*7Pmg84vZ4DiDS2g1yshkLV6zTe8&amp;site=stackoverflow&amp;run=true">something which gives</a> me some JSON like this for each question:</p>
  
  <pre><code>{
        "tags": [
          "c++",
          "opencl",
          "intel"
        ],
        "close_vote_count": 0,
        "title": "Weird OpenCL calls side effect on C++ for loop performance",
        "body": "&lt;p&gt;I'm working on a C++ project using OpenCL. I'm using the CPU as an OpenCL device with the  &lt;a href=\"http://registrationcenter.intel.com/irc_nas/5193/intel_code_builder_for_opencl_2015_ubuntu_5.0.0.43_x64.tgz\" rel=\"nofollow\"&gt;intel OpenCL runtime&lt;/a&gt;&lt;/p&gt;[...]"
      },
  </code></pre>
  
  <p><strong>Now, I want only questions which are closed.</strong></p>
  
  <p>How can I do this ?</p>
  
  <p>(another thing: How could I <em>exclude</em> closed questions from the results ?)</p>
