Библиотека (Library)
OpenLDAP LDAP (libldap, -lldap)
Синопсис (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 )
Описание (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 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.
Ошибки (Error)
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.
