The EventDnsBase class

(No version information available, might only be in SVN)

Introduction

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

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 void 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 )

}

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.

EventDnsBase::addNameserverIp — Adds a nameserver to the DNS base
EventDnsBase::addSearch — Adds a domain to the list of search domains
EventDnsBase::clearSearch — Removes all current search suffixes
EventDnsBase::__construct — Constructs EventDnsBase object
EventDnsBase::countNameservers — Gets the number of configured nameservers
EventDnsBase::loadHosts — Loads a hosts file (in the same format as /etc/hosts) from hosts file
EventDnsBase::parseResolvConf — Scans the resolv.conf-formatted file
EventDnsBase::setOption — Set the value of a configuration option
EventDnsBase::setSearchNdots — Set the 'ndots' parameter for searches
