       snmpa_notification_delivery_info_receiver -
           Behaviour module for the SNMP agent notification delivery
           information receiver.


       This module defines the behaviour of the notification delivery information receiver.

       A  snmpa_notification_delivery_info_receiver  compliant  module  must export the following

         * delivery_targets/3

         * delivery_info/4

       The semantics of them and their exact signatures are explained below.


       address() = A 4-tuple


       delivery_targets(Tag, Targets, Extra) -> void()


                 Tag = term()
                 Targets = [target()]
                 target() = {Address, Port}
                 Address = address()
                 Port = integer()
                 Extra = term()

              Inform about target addresses.

              This is the first function called when a notification delivery is in  progress.  It
              informs  the  receiver  which  targets will get the notification. The result of the
              delivery will be provided via successive calls  to  delivery_info/4  function,  see

       delivery_info(Tag, Target, DeliveryResult, Extra) -> void()


                 Tag = term()
                 Target = target()
                 target() = {Address, Port}
                 Address = address()
                 Port = integer()
                 DeliveryResult = delivery_result()
                 delivery_result() = no_response | got_response
                 Extra = term()

              Inform about delivery result.

              This   function  is  called  for  each  target  in  the  Targets  argument  of  the
              delivery_targets/3 function, see above.

              The purpose is to inform the receiver of  the  result  of  the  delivery  (was  the
              notification acknowledged or not) for each target.
