<concept id="GUID-76D1438E-445E-5864-BA9D-27BC61D72C1B" xml:lang="en"><title>How

to use CleanupClosePushL()</title><shortdesc>The CleanupClosePushL() templated function constructs and pushes

a TCleanupItem onto the cleanup stack.</shortdesc><prolog><metadata><keywords/></metadata></prolog><conbody>

<p>The <codeph>CleanupClosePushL()</codeph> templated function constructs

and pushes a <codeph>TCleanupItem</codeph> onto the cleanup stack. When <codeph>CleanupStack::PopAndDestroy()</codeph> is

called, the <codeph>Close()</codeph> member function of the object encapsulated

by the <codeph>TCleanupItem</codeph> is called.</p>

<codeblock id="GUID-78CAEA8F-8A04-5A57-837F-18D6019EFB7A" xml:space="preserve">...

RTestTwo two;

CleanupClosePushL(two);

...

CleanupStack::PopAndDestroy();

...</codeblock>

<p>The <codeph>TCleanupItem</codeph> object encapsulates a reference to the <codeph>RTestTwo</codeph> object;

the cleanup operation is the static function <codeph>Close()</codeph> of the

templated class <codeph>CleanupClose&lt;class         T&gt;</codeph>. This is

implemented by simply calling the <codeph>Close()</codeph> member function

of <codeph>RTestTwo</codeph>. This means that <codeph>RTestTwo</codeph> must

define or inherit a member function <codeph>Close()</codeph> which performs

whatever clean up is required.</p>
