<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>
documentation</a> for more details.
