+/**
+ * An operation for pushing objects to cleanup stack with \c TCleanupItems
+ * that will perform a \c ResetAndDestroy() operation on the pushed object
+ * if a leave occurs.
+ *
+ * Note that the object itself will not be deleted.
+ *
+ * @par Example:
+ * Here is an example of using \c CleanupResetAndDestroy with a dynamically
+ * allocated \c RPointerArray. \c RPointerArray clears its contents with a
+ * \cResetAndDestroy() operation.
+ * @code
+ *
+ *  // A function which creates a pointer array with couple of initialized
+ *  // CThings. The function must return a pointer to the pointer array,
+ *  // because the array has to be allocated dynamically. CThing is some
+ *  // simple CBase-derived class.
+ *
+ *  RPointerArray< CThing >* CreateThingArrayL( )
+ *      {
+ *      // Create an array of pointers to CThings with granularity of 4
+ *
+ *      RPointerArray< CThing >* things =
+ *          new( ELeave ) RPointerArray< CThing >( 4 );
+ *
+ *      // Push pointer to the array to the cleanup stack; then push reference
+ *      // to the array and a ResetAndDestroy operation to the cleanup stack.
+ *
+ *      // (Note that order of these operations matters: the ResetAndDestroy
+ *      // operation must be performed before the array itself is deleted.)
+ *
+ *      CleanupStack::PushL( things );
+ *      CleanupResetAndDestroyPushL( *things );
+ *
+ *      // Add couple of CThings with magic numbers to the array.
+ *      // If any of the NewL() operations leaves, the array will be cleared
+ *      // with ResetAndDestroy() and the array itself will destroyed.
+ *
+ *      User::LeaveIfError( things->Append( CThing::NewL( 7 ) ) );
+ *      User::LeaveIfError( things->Append( CThing::NewL( 96 ) ) );
+ *      User::LeaveIfError( things->Append( CThing::NewL( 999 ) ) );
+ *
+ *      // Pop the array reference with ResetAndDestroy from cleanup stack
+ *      // then pop the pointer to the array itself.
+ *
+ *      CleanupStack::Pop(); // *things
+ *      CleanupStack::Pop(); // things
+ *
+ *      // Now we're ready to return the results (a pointer to the array)
+ *      return things;
+ *      }
