Chapter1.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
