Overview

Creating an instance of a T–class into heap with a new operator

Description

It is possible to create an instance of a T–class with a new operator, but these precautions must be taken:

• Instances of T–Classes can be safely placed into the CleanupStack, assuming that they do not contain any pointers or references to external objects. CleanupStack handles the cleanup simply by calling User::Free().
• Member variables are not zeroed automatically on construction. Only CBase’s new operator zeroes members.
