LDAP_FIRST_ENTRY(3)OpenLDAP 2.2.23 (2005/01/24LDAP_FIRST_ENTRY(3)
NAME
ldap_first_entry, ldap_next_entry, ldap_count_entries - LDAP
result entry parsing and counting routines
LIBRARY
OpenLDAP LDAP (libldap, -lldap)
SYNOPSIS
#include <ldap.h>
int ldap_count_entries( LDAP *ld, LDAPMessage *result )
LDAPMessage *ldap_first_entry( LDAP *ld, LDAPMessage *result )
LDAPMessage *ldap_next_entry( LDAP *ld, LDAPMessage *entry )
DESCRIPTION
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().
ERRORS
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.
