title: Use ctypes with typedef
body: <p>I would like to call a C function</p>
  
  <pre><code>void initialize(My_Session* session, My_Status* status);
  </code></pre>
  
  <p>from Python using ctypes. The datatypes are defined by</p>
  
  <pre><code>typedef uint32_t My_Session;
  typedef int32_t My_Status;
  </code></pre>
  
  <p>Now I would like to know how I can pass the arguments using ctypes. Do I use <code>c_uint32</code> and <code>c_int32</code>, or do I have to define a class like it is done for structures?</p>
