LDAP_FIRST_ENTRY(3)					     Library Functions Manual					       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, 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 indi-
       cate 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.
