<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>
