# snmpa_notification_delivery_info_receiver

### MODULE

snmpa_notification_delivery_info_receiver

### MODULE SUMMARY

Behaviour module for the SNMP agent notification delivery information receiver.

### DESCRIPTION

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

A snmpa_notification_delivery_info_receiver compliant module must export the following functions:

- delivery_targets/3

- delivery_info/4

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

### DATA TYPES

    address() = A 4-tuple

### EXPORTS

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

Types:

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 below.

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

Types:

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.
