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.
