LDAP_FIRST_REFERENCE(3)                        Library Functions Manual                       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 )

       LDAPMessage *ldap_first_reference( 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()  routine  is  used  to retrieve the first reference 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_reference() to get the next reference mes‐
       sage, the result of which should be supplied to the next call to ldap_next_reference(), etc.  ldap_next_refer‐
       ence() 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_refer‐
       ences().  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() or ldap_next_reference(), NULL is returned.  If an error occurs
       in ldap_count_references(), -1 is returned.
