How to fix leaks in a dll</h2>
<h3>
<a NAME="Stage 1: nsIModule conversion"></a>Stage 1: nsIModule conversion</h3>
<ol>
<li>
Convert dll to use nsIModule. Sample code is in&nbsp; <a href="http://lxr.mozilla.org/seamonkey/source/xpcom/sample/nsSampleModule.cpp">mozilla/xpcom/sample/nsSampleModule.cpp</a></li>
</ol>
<h3>
<a NAME="Stage 2: Leak fixing"></a>Stage 2: Leak fixing</h3>
<ol>
<li>
While in purify run <a href="http://lxr.mozilla.org/seamonkey/source/xpcom/tests/TestShutdown.cpp">bin/TestShutdown</a>
on the dll. For this you will need to find a CID that the module implements.
Then invoke TestShutdown as</li>
<ol>% TestShutdown {123d4-4908-490840-409850}</ol>
<li>
Make sure there are no leaks from the purify output.</li>
<br>Use ns&lt;dll>Module::Shutdown() to release any global memory that
is being leaked.</ol>
