<h1>Description</h1>
<p>When an error occurs in the Berkeley DB library, an exception is thrown.  In
some cases, however, the <b>errno</b> value may be insufficient to
completely describe the cause of the error, especially during initial
application debugging.
<p>The DbEnv.set_error_stream method is used to enhance the mechanism for
reporting error messages to the application by setting a OutputStream
to be used for displaying additional Berkeley DB error messages.  In some cases,
when an error occurs, Berkeley DB will output an additional error message to
the specified stream.
<p>The error message will consist of the prefix string and a colon
("<b>:</b>") (if a prefix string was previously specified using
<a href="../api_java/env_set_errpfx.html">DbEnv.set_errpfx</a>), an error string, and a trailing
&lt;newline&gt; character.
<p>Alternatively, you can use the <a href="../api_java/env_set_errcall.html">DbEnv.set_errcall</a> method to capture the
additional error information in a way that does not use output streams.
You should not mix these approaches.
<p>This error logging enhancement does not slow performance or significantly
increase application size, and may be run during normal operation as well
as during application debugging.
