# The EventDnsBase class

(PECL event >= 1.2.6-beta)

## Introduction

Represents Libevent's DNS base structure. Used to resolve DNS asyncronously, parse configuration files like resolv.conf etc.

## Class synopsis

final EventDnsBase {
/* Constants */
const integer OPTION_SEARCH = 1 ;
const integer OPTION_NAMESERVERS = 2 ;
const integer OPTION_MISC = 4 ;
const integer OPTION_HOSTSFILE = 8 ;
const integer OPTIONS_ALL = 15 ;
/* Methods */
public bool addNameserverIp ( string `$ip` )
public void addSearch ( string `$domain` )
public void clearSearch ( void )
public __construct ( EventBase `$base` , bool `$initialize` )
public int countNameservers ( void )
public bool loadHosts ( string `$hosts` )
public bool parseResolvConf ( int `$flags` , string `$filename` )
public bool setOption ( string `$option` , string `$value` )
public bool setSearchNdots ( int `$ndots` )
}

## Predefined Constants

`EventDnsBase::OPTION_SEARCH`

  Tells to read the domain and search fields from the resolv.conf file and the ndots option, and use them to decide which domains(if any) to search for hostnames that aren’t fully-qualified.

`EventDnsBase::OPTION_NAMESERVERS`

  Tells to learn the nameservers from the resolv.conf file.

`EventDnsBase::OPTION_MISC`

`EventDnsBase::OPTION_HOSTSFILE`

  Tells to read a list of hosts from /etc/hosts as part of loading the resolv.conf file.

`EventDnsBase::OPTIONS_ALL`

  Tells to learn as much as it can from the resolv.conf file.
