    16 is a concern that memory, as a limited resource, is carefully handled, particularly

    17 in the event of error conditions. For this reason, exception handling and

    18 memory management are closely tied together in the Cleanup Support API.</p> </section>

    19 <section id="GUID-C176F084-C218-41EC-8C8C-AD5E74235382"><title>Architectural relationships</title> <p>The Uikon framework

    20 uses these APIs to provide to each GUI program the basic infrastructure for

    21 well-behaved memory handling. In particular, each GUI program has support

    22 for cleaning up memory in exception conditions, and, in debug builds, detection

    23 of memory leaks. </p> </section>
