<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 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 calls 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.
|
|
