<p><!-- CL 497837 --> The special comment that precedes
  <code>import</code> <code>"C"</code> may now include two
  new <code>#cgo</code> directives.
  <ul>
    <li>
      <code>#cgo</code> <code>noescape</code> <code>cFunctionName</code>
      tells cgo that Go pointers passed to the C function
      <code>cFunctionName</code> do not escape.
    </li>
    <li>
      <code>#cgo</code> <code>nocallback</code> <code>cFunctionName</code>
      tells cgo that the C function <code>cFunctionName</code> does
      not call any Go functions.
    </li>
  </ul>
  See <a href="/cmd/cgo#hdr-Optimizing_calls_of_C_code">the <code>cgo</code>
