Every object allocated on the heap should be protected by pushing its pointer to the cleanup stack via CleanupStack::PushL. Kernel resources used by the R-objects like RPointerArray are protected via CleanupClosePushL.

Sometimes you’d like or have to protect all the RPointerArray content without pushing all the individual items to the cleanup stack. There are custom solutions for this purpose, but there is also a built-in facility – CleanupResetAndDestroyPushL. It is not well known and not widely used only because it is defined in a quite an unusual place - \epoc32\include\mmf\common\mmfcontrollerpluginresolver.h
