The Parallel Editing Notification (PEN) allows workspaces to receive notifications (messages) when parallel editing of objects occurs. The following different classes of messages are used:
The client has to register one or more callback functions which will be invoked upon reception of the the messages from database server. There is a high level interface available which should be sufficient for most normal applications. By using the high level interface, you leave all details to LIBLINCKS which handles the exchange with the database server. For special applications, you might need to use the low level interface, but then you must handle the reception and retrieval of messages in your own code.
