LDAP_FIRST_ENTRY(3)                                        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.
