ldap_first_reference, ldap_next_reference, ldap_count_references — Stepping through continuation references in a result chain

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.
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.
