LDAP_FIRST_ENTRY(3) LDAP_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(1,8), LDAPMessage *result )
LDAPMessage *ldap_first_entry( LDAP *ld(1,8), LDAPMessage *result )
LDAPMessage *ldap_next_entry( LDAP *ld(1,8), 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(1,8) 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(1,8) 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(1,8) calls to the routines described in(1,8)
ldap_get_dn(3), ldap_first_attribute(3), ldap_get_values(3), etc.
A count of the number of entries in(1,8) the search result can be obtained
by calling ldap_count_entries().
ERRORS
If an error(8,n) occurs in(1,8) ldap_first_entry() or ldap_next_entry(), NULL is
returned and the ld_errno field in(1,8) the ld(1,8) parameter is set(7,n,1 builtins) to indicate
the error. If an error(8,n) occurs in(1,8) ldap_count_entries(), -1 is returned,
and ld_errno is set(7,n,1 builtins) appropriately. See ldap_error(3) for a description
of possible error(8,n) codes.
