<p>
When an error occurs in the Berkeley DB library, a
<a href="T_BerkeleyDB_DatabaseException.htm">DatabaseException</a>, or subclass of DatabaseException,
is thrown. In some cases, however, the exception may be insufficient
to completely describe the cause of the error, especially during
initial application debugging.
</p>
<p>
In some cases, when an error occurs, Berkeley DB will call the given
delegate with additional error information. It is up to the delegate
to display the error message in an appropriate manner.
</p>
<p>
Setting ErrorFeedback to NULL unconfigures the callback interface.
</p>
<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.
</p>
<p>
For databases opened inside of a DatabaseEnvironment, setting
ErrorFeedback affects the entire environment and is equivalent to
setting DatabaseEnvironment.ErrorFeedback.
</p>
<p>
For databases not opened in an environment, setting ErrorFeedback
configures operations performed using the specified object, not all
operations performed on the underlying database.
