ldap_first_entry, ldap_next_entry, ldap_count_entries — LDAP result entry parsing and counting routines
#include <ldap.h>
int ldap_count_entries( |
LDAP *ld, |
LDAPMessage *result) ; |
LDAPMessage *ldap_first_entry( |
LDAP *ld, |
LDAPMessage *result) ; |
LDAPMessage *ldap_next_entry( |

LDAPMessage *entry) ; |
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.
