Functions for Registering Object Extensions

This section contains reference information on routines for registering object
extensions. This set of functions provides a means for extending core server
objects—this functionality is provided so that you can efficiently pass state
information between plug-in calls. Typically, a plug-in might register both a
pre-operation and post-operation call. It is very convenient for the plug-in to
associate its private data with the operation object that is passed through the
parameter block.
