LDAP_FIRST_ENTRY(3) Library Functions Manual LDAP_FIRST_ENTRY(3)
ldap_first_entry, ldap_next_entry, ldap_count_entries - LDAP
result entry parsing and counting routines
OpenLDAP LDAP (libldap, -lldap)
#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 )
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.
