Functions for Registering Object Extensions
546 Netscape Directory Server Plug-In Programmer’s Guide • December 2003
Returns
This function returns a pointer to the plug-in’s extension.
Description
A plug-in retrieves a pointer to its own extension by calling
slapi_get_object_extension
with the object from which the extension is to be
retrieved. The factory uses
objecttype
to find the offset into the object of where
the extension block is stored. The extension handle is then used to find the
appropriate extension within the block.
