<h3>Description: DbMemoryException</h3>
<p>This information describes the DbMemoryException class and how
it is used by the various Db* classes.</p>
<p>A DbMemoryException is thrown when there is insufficient memory
to complete an operation, and there is the possibility of recovering.
An example is during a <a href="../../db42-devel-4.2.52/api_cxx/db_get.html">Db::get</a> or <a href="../../db42-devel-4.2.52/api_cxx/dbc_get.html">Dbc::get</a> operation with
the <a href="../../db42-devel-4.2.52/api_cxx/dbt_class.html">Dbt</a> flags set to <a href="../../db42-devel-4.2.52/api_cxx/dbt_class.html#DB_DBT_USERMEM">DB_DBT_USERMEM</a>.</p>
<p>The <b>get_dbt</b> method returns the
<a href="../../db42-devel-4.2.52/api_cxx/dbt_class.html">Dbt</a> with insufficient memory to complete the operation, causing
the DbMemoryException to be thrown.
The <a href="../../db42-devel-4.2.52/api_cxx/dbt_class.html">Dbt</a> pointer may or may not refer to valid memory, depending
on whether the <a href="../../db42-devel-4.2.52/api_cxx/dbt_class.html">Dbt</a> used in the call to the failed Berkeley DB method
is still in scope and has not been deleted.</p>
