ldap_first_reference(3) ldap_first_reference(3)
NAME
ldap_first_reference, ldap_next_reference, ldap_count_references -
Stepping through continuation references in a result chain
LIBRARY
OpenLDAP LDAP (libldap, -lldap)
SYNOPSIS
#include <ldap.h>
int ldap_count_references( LDAP *ld, LDAPMessage *result )
ldap_first_reference(3) LDAP *ld, LDAPMessage *result )
LDAPMessage *ldap_next_reference( LDAP *ld, LDAPMessage *reference )
DESCRIPTION
These routines are used to step through the continuation references in
a result chain received from ldap_result(3) or the synchronous LDAP
search operation routines.
The ldap_first_reference(3) routine is used to retrieve the first refer-
ence message in a result chain. It takes the result as returned by a
call to ldap_result(3), ldap_search_s(3) or ldap_search_st(3) and
returns a pointer to the first reference message in the result chain.
This pointer should be supplied on a subsequent call to ldap_next_ref-
erence() to get the next reference message, the result of which should
be supplied to the next call to ldap_next_reference(), etc.
ldap_next_reference() will return NULL when there are no more reference
messages. The reference messages returned from these calls are used by
ldap_parse_reference(3) to extract referrals and controls.
A count of the number of reference messages in the search result can be
obtained by calling ldap_count_references(). It can also be used to
count the number of reference messages remaining in a result chain.
ERRORS
If an error occurs in ldap_first_reference(3) or ldap_next_reference(),
NULL is returned. If an error occurs in ldap_count_references(), -1 is
returned.
