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.
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.
