Deleting and Unregistering a Message Pattern

If delivered messages that matched the deleted pattern have not been retrieved by your application (for example, the messages might be queued), the ToolTalk service does not destroy these messages.

To delete a message pattern, use the tt_pattern_destroy() function. This function first unregisters the pattern and then destroys the pattern object.

To stop receiving messages that match a message pattern without destroying the pattern object, use the tt_pattern_unregister() to unregister the pattern.

The ToolTalk service will automatically unregister and destroy all message pattern objects when you call tt_close.
