IPInfo Class

Properties   Methods   Events   Config Settings   Errors  

The IPInfo class is used to resolve host names to host addresses and vice versa using an asynchronous DNS. The class provides access to other Transmission Control Protocol (TCP)/IP database functions as well.

Syntax

IPInfo

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).

Setting this property to a particular protocol name (e.g., 'udp' or 'tcp') will force a search for a service for that protocol only. If this property is set to "" (empty string), then the first entry for the service will be returned and this property will be set to the corresponding protocol.

Note: This functionality is only available in Windows.

Data Type

String

Config Method (IPInfo Class)

Sets or retrieves a configuration setting.

Syntax

• C++
• C
• Qt

ANSI (Cross Platform)
char* Config(const char* lpszConfigurationString);

Unicode (Windows)
LPWSTR Config(LPCWSTR lpszConfigurationString);

char* ipworks_ipinfo_config(void* lpObj, const char* lpszConfigurationString);

QString Config(const QString& qsConfigurationString);

Remarks

Config is a generic method available in every class. It is used to set and retrieve configuration settings for the class.

These 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.

To set a configuration setting named PROPERTY, you must call Config("PROPERTY=VALUE"), where VALUE is the value of the setting expressed as a string. For boolean values, use the strings "True", "False", "0", "1", "Yes", or "No" (case does not matter).

To read (query) the value of a configuration setting, you must call Config("PROPERTY"). The value will be returned as a string.

Error Handling (C++)

This method returns a String value; after it returns, call the GetLastErrorCode() method to obtain its result code; 0 indicates success, while a non-zero error code indicates that this method encountered an error during its execution. If an error occurs, the GetLastError() method can be called to retrieve the associated error message.

virtual int FireDNSCacheEntry(IPInfoDNSCacheEntryEventParams *e);

typedef struct {
  const char *RecordName;
  int RecordType;
  int TimeToLive;
  int DataLength;
  const char *Section;
  const char *RecordValue;
  const char *RecordInfo;
  int reserved;
} IPInfoDNSCacheEntryEventParams;


Unicode (Windows)
virtual INT FireDNSCacheEntry(IPInfoDNSCacheEntryEventParams *e);

typedef struct {
  LPCWSTR RecordName;
  INT RecordType;
  INT TimeToLive;
  INT DataLength;
  LPCWSTR Section;
  LPCWSTR RecordValue;
  LPCWSTR RecordInfo;
  INT reserved;
} IPInfoDNSCacheEntryEventParams;

#define EID_IPINFO_DNSCACHEENTRY 1

virtual INT IPWORKS_CALL FireDNSCacheEntry(LPSTR &lpszRecordName, INT &iRecordType, INT &iTimeToLive, INT &iDataLength, LPSTR &lpszSection, LPSTR &lpszRecordValue, LPSTR &lpszRecordInfo);

class IPInfoDNSCacheEntryEventParams {
public:
  const QString &RecordName();

  int RecordType();

  int TimeToLive();

  int DataLength();

  const QString &Section();

  const QString &RecordValue();

  const QString &RecordInfo();

  int EventRetVal();
  void SetEventRetVal(int iRetVal);
};

// To handle, connect one or more slots to this signal.
void DNSCacheEntry(IPInfoDNSCacheEntryEventParams *e);

// Or, subclass IPInfo and override this emitter function.
virtual int FireDNSCacheEntry(IPInfoDNSCacheEntryEventParams *e) {...}

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 (IPInfo Class)

Fired when information is available about errors during data delivery.

Syntax

• C++
• C
• Qt

ANSI (Cross Platform)
virtual int FireError(IPInfoErrorEventParams *e);

typedef struct {
  int ErrorCode;
  const char *Description;
  int reserved;
} IPInfoErrorEventParams;


Unicode (Windows)
virtual INT FireError(IPInfoErrorEventParams *e);

typedef struct {
  INT ErrorCode;
  LPCWSTR Description;
  INT reserved;
} IPInfoErrorEventParams;

#define EID_IPINFO_ERROR 2

virtual INT IPWORKS_CALL FireError(INT &iErrorCode, LPSTR &lpszDescription);

class IPInfoErrorEventParams {
public:
  int ErrorCode();

  const QString &Description();

  int EventRetVal();
  void SetEventRetVal(int iRetVal);
};

// To handle, connect one or more slots to this signal.
void Error(IPInfoErrorEventParams *e);

// Or, subclass IPInfo and override this emitter function.
virtual int FireError(IPInfoErrorEventParams *e) {...}

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 (IPInfo Class)

This event is fired after an asynchronous request completes.

Syntax

• C++
• C
• Qt

ANSI (Cross Platform)
virtual int FireRequestComplete(IPInfoRequestCompleteEventParams *e);

typedef struct {
  int RequestId;
  int StatusCode;
  const char *Description;
  int reserved;
} IPInfoRequestCompleteEventParams;


Unicode (Windows)
virtual INT FireRequestComplete(IPInfoRequestCompleteEventParams *e);

typedef struct {
  INT RequestId;
  INT StatusCode;
  LPCWSTR Description;
  INT reserved;
} IPInfoRequestCompleteEventParams;

#define EID_IPINFO_REQUESTCOMPLETE 3

virtual INT IPWORKS_CALL FireRequestComplete(INT &iRequestId, INT &iStatusCode, LPSTR &lpszDescription);

class IPInfoRequestCompleteEventParams {
public:
  int RequestId();

  int StatusCode();

  const QString &Description();

  int EventRetVal();
  void SetEventRetVal(int iRetVal);
};

// To handle, connect one or more slots to this signal.
void RequestComplete(IPInfoRequestCompleteEventParams *e);

// Or, subclass IPInfo and override this emitter function.
virtual int FireRequestComplete(IPInfoRequestCompleteEventParams *e) {...}

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.
