<h1>Description</h1>
<p>This manual page describes the DbMemoryException class and how
it is used by the various Db* classes.
<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="../api_cxx/db_get.html">Db::get</a> or <a href="../api_cxx/dbc_get.html">Dbc::get</a> operation with
the <a href="../api_cxx/dbt_class.html">Dbt</a> flags set to <a href="../api_cxx/dbt_class.html#DB_DBT_USERMEM">DB_DBT_USERMEM</a>.
<p>The <b>get_dbt</b> method returns the <a href="../api_cxx/dbt_class.html">Dbt</a> that has insufficient
memory to complete the operation, causing the DbMemoryException
to be thrown.
The <a href="../api_cxx/dbt_class.html">Dbt</a> pointer may or may not refer to valid memory, depending
on whether the <a href="../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.
