The EventDnsBase class

(PECL event >= 1.2.6-beta)

Introducere

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

final EventDnsBase {

/* Constants */

const int OPTION_SEARCH = 1 ;

const int OPTION_NAMESERVERS = 2 ;

const int OPTION_MISC = 4 ;

const int OPTION_HOSTSFILE = 8 ;

const int OPTIONS_ALL = 15 ;

/* Metode */

public addNameserverIp ( string $ip ) : bool

public addSearch ( string $domain ) : void

public clearSearch ( ) : void

public __construct ( EventBase $base , bool $initialize )

public countNameservers ( ) : int

public loadHosts ( string $hosts ) : bool

public parseResolvConf ( int $flags , string $filename ) : bool

public setOption ( string $option , string $value ) : bool

public setSearchNdots ( int $ndots ) : bool

}

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
