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.
