 ipworks_ipinfo_do_reset($res);
 ipworks_ipinfo_do_resolveaddress($res, $hostaddress);
 ipworks_ipinfo_do_resolvename($res, $hostname);

Remarks

The IPInfo class operates asynchronously. Requests are posted to the class by setting a property like HostName or HostAddress and then waiting for the RequestComplete event. The RequestId property identifies the request.

Up to 100 simultaneous requests can be queued at any moment. PendingRequests shows the number of pending requests and also may be used to adjust the size of the queue (by dumping a number of the pending requests).

public function fireDNSCacheEntry($param);

Procedural Interface

ipworks_ipinfo_register_callback($res, 1, array($this, 'fireDNSCacheEntry'));

Parameter List

 'recordname'
 'recordtype'
 'timetolive'
 'datalength'
 'section'
 'recordvalue'
 'recordinfo'

Remarks

This event fires once for each entry in the local DNS cache when DisplayDNSCache is called.

RecordName is the host name to which the record applies.

RecordType is the type of response. For instance 1 is an A record.

TimeToLive is the time in seconds after which the cached entry expires.

DataLength is the length of the data in bytes. For instance, if the RecordType is A and an IPv4 address is cached, its DataLength would be 4. CNAME and PTR records will contain the length of the address in memory where the value is held.

Section is the section of the DNS response from which the record is taken. Most commonly, this is the "Answer" section.

RecordValue is the actual value that is cached. For instance this may be an IP address for A records.

RecordInfo is a text representation of the other parameters. This is suitable for use in a log file or to display.

Error Event (IPWorks_IPInfo Class)

Fired when information is available about errors during data delivery.

Object Oriented Interface

public function fireError($param);

Procedural Interface

ipworks_ipinfo_register_callback($res, 2, array($this, 'fireError'));

Parameter List

 'errorcode'
 'description'

Remarks

The Error event is fired in case of exceptional conditions during message processing. Normally the class fails with an error.

The ErrorCode parameter contains an error code, and the Description parameter contains a textual description of the error. For a list of valid error codes and their descriptions, please refer to the Error Codes section.

RequestComplete Event (IPWorks_IPInfo Class)

This event is fired after an asynchronous request completes.

Object Oriented Interface

public function fireRequestComplete($param);

Procedural Interface

ipworks_ipinfo_register_callback($res, 3, array($this, 'fireRequestComplete'));

Parameter List

 'requestid'
 'statuscode'
 'description'

Remarks

The RequestId parameter specifies the request that just completed. The class properties that relate to this request are completed with the returned values. For example, in the case of domain name resolution, HostName, HostAddress, HostAliases, and OtherAddresses are set to the resolved values.

If the request completed normally, StatusCode is 0, and Description is "OK". If not, StatusCode has the error code returned by the system. Description contains a description of this code.

Please refer to the Error Codes section for more information.

NOTE: This functionality is only available in Windows.

Config Settings (IPInfo Class)

The class accepts one or more of the following configuration settings. Configuration settings are similar in functionality to properties, but they are rarely used. In order to avoid "polluting" the property namespace of the class, access to these internal properties is provided through the Config method.
