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