    std::vector<TYPE>* buffer);

Description

Remove up to the specified maxNumItems from the back of this container into the specified buffer. The removed items are appended to buffer as if by repeated application of buffer‐>push_back(popBack()) while the container is not empty and maxNumItems have not yet been removed.

Also note that *buffer is not cleared ‐‐ the popped items are appended after any pre‐existing contents.
