<p>
In some cases, when an error occurs, Berkeley DB will call
ErrorFeedback with additional error information. It is up to the
delegate function to display the error message in an appropriate
manner.
</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 Berkeley DB environments, setting
ErrorFeedback affects the entire environment and is equivalent to
setting <a href="P_BerkeleyDB_DatabaseEnvironment_ErrorFeedback.htm">ErrorFeedback</a>.
