.SH NAME
snmpa_notification_delivery_info_receiver \- 
    Behaviour module for the SNMP agent notification delivery 
    information receiver.
  
.SH DESCRIPTION
.LP
This module defines the behaviour of the notification delivery information receiver\&.
.LP
A \fIsnmpa_notification_delivery_info_receiver\fR\& compliant module must export the following functions:
.RS 2
.TP 2
*
delivery_targets/3
.LP
.TP 2
*
delivery_info/4
.LP
.RE

.LP
The semantics of them and their exact signatures are explained below\&.
.LP
Legacy notification delivery information receiver modules used a target argument on the form \fI{IpAddr, PortNumber}\fR\& instead of \fI{Domain, Addr}\fR\&, and if the SNMP Agent is run without changing the configuration to use transport domains the notification delivery information receiver will still get the old arguments and work as before\&.
.SH "DATA TYPES"

See the  data types in \fIsnmpa_conf\fR\&\&.

.LP
Inform about target addresses\&.
.LP
This is the first function called when a notification delivery is in progress\&. It informs the \fIreceiver\fR\& which targets will get the notification\&. The result of the delivery will be provided via successive calls to \fIdelivery_info/4\fR\& function, see below\&.

Types:

.RS 3
Tag = term()

Targets = [Target]

.LP
Inform about delivery result\&.
.LP
This function is called for each target in the \fITargets\fR\& argument of the \fIdelivery_targets/3\fR\& function, see above\&.
.LP
The purpose is to inform the \fIreceiver\fR\& of the result of the delivery (was the notification acknowledged or not) for each target\&.
