<pre style="white-space: pre-wrap; white-space: -moz-pre-wrap; white-space: -pre-wrap; white-space: -o-pre-wrap; word-wrap: break-word;">I think the documentation should strongly discourage the use of these functions unless they are absolutely necessary. It's fairly expensive (a malloc() per item in the container).</pre>

<pre style="white-space: pre-wrap; white-space: -moz-pre-wrap; white-space: -pre-wrap; white-space: -o-pre-wrap; word-wrap: break-word;">In Richard's defense, this is (I think) just as costly as using a OBJ_MULTIPLE iterator. This mechanism at least tells you that you are cloning the container, which somewhat implies that it isn't going to be a cheap operation.</pre>

Some reasons you might need to do this:
1) You need to reconfigure a container. You would do this by creating a new container with the new configuration and ao2_container_dup the old container into it. Then replace the old container with the new. Then destroy the old container.
2) You need the contents of a container to remain stable while operating on all of the objects. You would do this by creating a cloned container of the original with ao2_container_clone. The cloned container is a snapshot of the objects at the time of the cloning. When done, just destroy the cloned container.</pre>
