slapi_filter_join()

Joins the two specified filters using one of the following filter types: LDAP_FILTER_AND, LDAP_FILTER_OR, or LDAP_FILTER_NOT. (When specifying the filter type LDAP_FILTER_NOT, the second filter should be NULL.)

#include "slapi-plugin.h"
Slapi_Filter *slapi_filter_join( int ftype, Slapi_Filter *f1, Slapi_Filter *f2 );

The function has the following parameters:
ftype
Type of composite filter you want to create.

f1
First filter that you want to join.

f2
Second filter that you want to join. If ftype is LDAP_FILTER_NOT, specify NULL for this argument.

The new filter constructed from the other two filters.

Description

Filters of the type LDAP_FILTER_AND, LDAP_FILTER_OR, and LDAP_FILTER_NOT generally consist of one or more other filters. For example:

(&(ou=Accounting)(l=Sunnyvale))

(|(ou=Accounting)(l=Sunnyvale))

(!(l=Sunnyvale))

Each of these examples contain one or more LDAP_FILTER_EQUALITY filters.

Call the slapi_filter_join() function to create a new filter of the type LDAP_FILTER_AND, LDAP_FILTER_OR, or LDAP_FILTER_NOT.
