       through messages in a result chain

       int ldap_count_messages( LDAP *ld, LDAPMessage *result )

       LDAPMessage *ldap_first_message( LDAP *ld, LDAPMessage *result )

       LDAPMessage *ldap_next_message( LDAP *ld, LDAPMessage *message )


       These routines are used to step through the messages in a result  chain
       received  from ldap_result(3).  For search operations, the result chain
       can contain referral, entry and result  messages.  The  ldap_msgtype(3)
       function  can  be  used  to  distinguish  between the different message

       The ldap_first_message() routine is used to retrieve the first  message
       in  a  result  chain.   It  takes  the  result as returned by a call to
       ldap_result(3), ldap_search_s(3) or  ldap_search_st(3)  and  returns  a
       pointer to the first message in the result chain.

       This   pointer   should   be   supplied   on   a   subsequent  call  to
       ldap_next_message() to get the next message, the result of which should
       be   supplied   to   the   next   call   to  ldap_next_message(),  etc.
       ldap_next_message() will return NULL when there are no more messages.

       These   functions    are    useful    when    using    routines    like
       ldap_parse_result(3)  that  only  operate  on  the  first result in the

       A count of the number of messages in the result chain can  be  obtained
       by  calling  ldap_count_messages().   It  can also be used to count the
       number of remaining messages in a chain if called with a message, entry
       or  reference  returned by ldap_first_message() , ldap_next_message() ,
       ldap_first_entry(3),    ldap_next_entry(3),    ldap_first_reference(3),


       If an error occurs in ldap_first_message() or ldap_next_message(), NULL
       is returned.  If  an  error  occurs  in  ldap_count_messages(),  -1  is
