Open Directory Callbacks
Open Directory provides three callback routines for plug-ins to call:
DSDebugLog. Writes an entry in the Open Directory log file. All records written by all Open Directory plug-ins are written to the same log file in the order by which Open Directory receives them.
DSRegisterNode. Registers a node so that it is available for use by applications that make Open Directory calls.
DSUnregisterNode. Unregisters a node that was previously registered.
The Open Directory callback routines are described in detail in the section Open Directory Callbacks” in the Reference section.
