ldap_first_entry, ldap_next_entry, ldap_count_entries — LDAP result entry parsing and counting routines

These routines are used to parse results received from ldap_result(3) or the synchronous LDAP search operation routines ldap_search_s(3) and ldap_search_st(3).
The ldap_first_entry()
routine is
used to retrieve the first entry in a chain of search
results. It takes the result
as returned by a call to
ldap_result(3) or ldap_search_s(3) or
ldap_search_st(3) and
returns a pointer to the first entry in the result.
This pointer should be supplied on a subsequent call to
ldap_next_entry()
to get the next entry, the result of which should be supplied
to the next call to ldap_next_entry()
, etc.
ldap_next_entry()
will return NULL when there are no more entries. The entries
returned from these calls are used in calls to the routines
described in ldap_get_dn(3), ldap_first_attribute(3),
ldap_get_values(3),
etc.
A count of the number of entries in the search result can
be obtained by calling ldap_count_entries()
.
If an error occurs in ldap_first_entry()
or
ldap_next_entry()
,
NULL is returned and the ld_errno field in the ld
parameter is set to indicate
the error. If an error occurs in ldap_count_entries()
, -1 is
returned, and ld_errno
is set
appropriately. See ldap_error(3) for a
description of possible error codes.
