Chapter 1. Admin Guide

1.1. Overview

This is a module which provides a UNIX/UDP SOCKET transport layer implementation for the Event Interface.

1.2. DATAGRAM events syntax

The raised events will follow the following grammar:

  • event = event_name (argument '\n')*

  • event_name = non-quoted_string'\n'

  • argument = ((arg_name '::')? arg_value)? | (arg_value)

  • arg_name = not-quoted_string

  • arg_value = not-quoted_string | '"' string '"'

  • not-quoted_string = string - {',",\n,\r}

The event name can contain any non-quoted string character, but it is recommended to follow the syntax: E_MODULE_NAME_EXTRA_NAME

1.3. DATAGRAM socket syntax

There are two types of sockets used by this module, based on the sockets type. An UNIX socket should follow this syntax:

['unix:'] unix_socket_path

An UDP socket should follow this syntax:

'udp:' address ':' port

1.4. Dependencies

E_PIKE_BLOCKED
ip::192.168.2.11

Example 1.2. UNIX socket


unix:/tmp/opensips_event.sock

Example 1.3. UDP socket


udp:127.0.0.1:8081
