.SH DESCRIPTION
|
|
.LP
|
|
These routines are used to step through the continuation references in a
|
|
result chain received from
|
|
.BR ldap_result (3)
|
|
or the synchronous LDAP search operation routines.
|
|
.LP
|
|
The
|
|
.B ldap_first_reference()
|
|
routine is used to retrieve the first reference message in a
|
|
result chain. It takes the \fIresult\fP as returned by a call to
|
|
.BR ldap_result (3) ,
|
|
.BR ldap_search_s (3)
|
|
or
|
|
.BR ldap_search_st (3)
|
|
and returns a pointer to the first reference message in the
|
|
result chain.
|
|
.LP
|
|
This pointer should be supplied on a subsequent call to
|
|
.B ldap_next_reference()
|
|
to get the next reference message, the result of which should be
|
|
supplied to the next call to
|
|
.BR ldap_next_reference() ,
|
|
etc.
|
|
.B ldap_next_reference()
|
|
will return NULL when there are no more reference messages.
|
|
The reference messages returned from these calls are used by
|
|
.BR ldap_parse_reference (3)
|
|
to extract referrals and controls.
|
|
.LP
|
|
A count of the number of reference messages in the search result can be
|
|
obtained by calling
|
|
.BR ldap_count_references() .
|
|
It can also be used to count the number of reference messages remaining
|
|
in a result chain.
|
|
.SH ERRORS
|
|
If an error occurs in
|
|
.B ldap_first_reference()
|
|
or
|
|
.BR ldap_next_reference() ,
|
|
NULL is returned. If an error occurs in
|
|
.BR ldap_count_references() ,
|
|
-1 is returned.
