Registering Your Plug-in Functions
Whether you register your plug-in through the initialization function depends
upon the type of function you are registering.
For some plug-in types, you do not need to register the plug-in function from
within the initialization function. For example, you register entry store and entry
fetch plug-ins by specifying the function names in the
dse.ldif
For other plug-in types, such as pre-operation plug-ins and post-operation
plug-ins, the Directory Server gets the pointer to your function from a parameter
in the initialization function parameter block. In these cases, you use the
slapi_pblock_set()
The full list parameters that you can use to register your plug-in functions are
listed in "Parameters for Registering Plug-in Functions," on page 570.
For example, if you want to register
pre-operation search function, include the following code in your initialization
function:
slapi_pblock_set( pb, SLAPI_PLUGIN_PRE_SEARCH_FN, \
SLAPI_PLUGIN_PRE_SEARCH_FN
