<div class="textblock"><p>Basic functionality for a <em>safe</em> iterator. </p>
<p>The _Safe_iterator_base base class implements the functionality of a safe iterator that is not specific to a particular iterator type. It contains a pointer back to the sequence it references along with iterator version information and pointers to form a doubly-linked list of iterators referenced by the container.</p>
<p>This class must not perform any operations that can throw an exception, or the exception guarantees of derived iterators will be broken. </p>
