  32           Example, given a function <code class="computeroutput"><span class="identifier">foo</span></code>:
  33         </p>
  34 <pre class="programlisting"><span class="keyword">void</span> <span class="identifier">foo</span><span class="special">(</span><span class="keyword">int</span> <span class="identifier">n</span><span class="special">)</span>

  38 </pre>
  39 <p>
  40           Here's how the function <code class="computeroutput"><span class="identifier">foo</span></code>
  41           may be bound:
  42         </p>
  43 <pre class="programlisting"><span class="identifier">bind</span><span class="special">(&amp;</span><span class="identifier">foo</span><span class="special">,</span> <span class="identifier">arg1</span><span class="special">)</span>
  44 </pre>
  45 <p>
  46           This is now a full-fledged expression that can finally be evaluated by
  47           another function call invocation. A second function call will invoke the
  48           actual <code class="computeroutput"><span class="identifier">foo</span></code> function. Example:
  49         </p>
  50 <pre class="programlisting"><span class="identifier">bind</span><span class="special">(&amp;</span><span class="identifier">foo</span><span class="special">,</span> <span class="identifier">arg1</span><span class="special">)(</span><span class="number">4</span><span class="special">);</span>
  51 </pre>
  52 <p>
  53           will print out "4".
