Netscape DIRECTORY SERVER 6.2 - PLUG-IN Manual page 180

Summary of Data Types and Structures
You need to define the filter matching function, which is the function that has
prototype specified by
potential matching candidate entry. The server passes pointers to a filter structure
(that you create in your filter factory function — see "Writing a Filter Factory
Function"), the candidate entry, and the entry's attributes.
In your filter matching function, you can retrieve information about the filter (such
as the attribute type and value specified in the filter) from the filter structure. You
can then use this information to compare the value in the filter against the attribute
values in the candidate entry.
For more information on writing a filter matching function, see "Writing a Filter
Matching Function."
