Writing a Filter Matching Function
The filter matching function has the following prototype:
#include "slapi-plugin.h"
typedef int (*mrFilterMatchFn) (void* filter,
This function passes the following arguments:
•
filter
•
entry
the filter.
•
attrs
attributes. (The extensible match filter might specify that the attributes in the
DN of an entry should also be included in the search.)
This function will never be called for the same filter object concurrently. (If you

function concurrently for different filter objects.)
The filter matching function should do the following:
From the filter object, get the attribute type, the values, and the query operator.
