Cleanup utilities

The Cleanup utility functions support four types of clean up operation.

The cleanup utility functions offer easy ways of constructing a TCleanUpItem and pushing it onto the cleanup stack. They support four types of clean up operation:

where the object is deleted: template <class T> void CleanupDeletePushL(T*)
where the object's Close() member function is called: template <class T> void CleanupClosePushL(T&)
where the object's Release() member function is called: template <class T> void CleanupReleasePushL(T&)
where an array of objects is deleted: template <class T> void CleanupArrayDeletePushL(T*)

The functions have the supporting templated classes:

CleanupDelete<class T>
CleanupClose<class T>
CleanupRelease<class T>
CleanupArrayDelete<class T>

The way in which these work is best illustrated graphically by taking CleanupClosePushL() as an example. See the diagram below.
