<p>The Db::set_error_model method is gone. The way to change the C++ API to
|
||
return errors rather than throw exceptions is via a flag on the DbEnv or
|
||
Db constructor. For example:</p>
|
||
<pre class="programlisting">int dberr;
|
||
DbEnv *dbenv = new DbEnv(DB_CXX_NO_EXCEPTIONS);</pre>
|
||
<p>creates an environment that will never throw exceptions, and method
|
||
returns should be checked instead.</p>
|
||
<p>There are a number of smaller changes to the API that bring the C, C++
|
||
and Java APIs much closer in terms of functionality and usage. Please
|
||
refer to the pages for upgrading C applications for further details.</p>
