UDP Class
Properties Methods Events Config Settings Errors
The User Datagram Protocol (UDP) class is used to facilitate UDP (datagram) communications. It can act both as a client and a server and communicate with any number of hosts simultaneously, as well as generate and receive broadcast packets.
Class Name
IPWorks_UDP
Procedural Interface
ipworks_udp_open(); ipworks_udp_close($res); ipworks_udp_register_callback($res, $id, $function); ipworks_udp_get_last_error($res); ipworks_udp_get_last_error_code($res); ipworks_udp_set($res, $id, $index, $value); ipworks_udp_get($res, $id, $index); ipworks_udp_do_activate($res); ipworks_udp_do_config($res, $configurationstring); ipworks_udp_do_deactivate($res); ipworks_udp_do_doevents($res); ipworks_udp_do_pausedata($res); ipworks_udp_do_processdata($res); ipworks_udp_do_reset($res); ipworks_udp_do_resolveremotehost($res); ipworks_udp_do_send($res, $text); ipworks_udp_do_sendbytes($res, $data); ipworks_udp_do_sendtext($res, $text);
Remarks
The interface of the class is similar to the interface of TCPClient, only much simpler. The class is activated or deactivated through the Active property. This property enables or disables sends or receives. The data can be sent in the same way as TCPClient, using the Send method and specifying the text to send. The destination is specified using the RemoteHost and RemotePort properties. Inbound data are received through the DataIn event.
If the UseConnection configuration setting is set to True, then a local association is created with the remote host. Otherwise, the class can receive datagrams (packets) from any host, and send datagrams to any host. Packets can be broadcast on the local net by setting the destination (RemoteHost) to 255.255.255.255.
The operation of the class is almost completely asynchronous. All calls, except the ones that deal with domain name resolution, operate through Windows messages (no blocking calls). The gain in performance is considerable when compared to using blocking calls.

AcceptData Property (IPWorks_UDP Class)
This property indicates whether data reception is currently enabled.
Object Oriented Interface
public function getAcceptData();
Procedural Interface
ipworks_udp_get($res, 1 );
Default Value
true
Remarks
This property indicates whether data reception is currently enabled. When false, data reception is disabled and the DataIn event will not fire. Use the PauseData and ProcessData methods to pause and resume data reception.
This property is read-only and not available at design time.
Data Type
Boolean
Active Property (IPWorks_UDP Class)
This property indicates whether the class is active.
Object Oriented Interface
public function getActive();
Procedural Interface
ipworks_udp_get($res, 2 );
Default Value
false
Remarks
This property indicates whether the class is currently active and can send or receive data. Use the Activate and Deactivate methods to control whether the class is active.
This property is read-only and not available at design time.
Data Type
Boolean
DontRoute Property (IPWorks_UDP Class)
If this property is set to True, it forces the socket to send data directly to the interface (no routing).
Object Oriented Interface
public function getDontRoute(); public function setDontRoute($value);
Procedural Interface
ipworks_udp_get($res, 3 ); ipworks_udp_set($res, 3, $value );
Default Value
false
Remarks
If this property is set to True, it forces the socket to send data directly to the interface (no routing). Normally, IP sockets send packets of data through routers and gateways until they reach the final destination. If this property is set to True, then data will be delivered on the local subnet only.
This property is not available at design time.
Data Type
Boolean
LocalHost Property (IPWorks_UDP Class)
This property includes the name of the local host or user-assigned IP interface through which connections are initiated or accepted.
Object Oriented Interface
public function getLocalHost(); public function setLocalHost($value);
Procedural Interface
ipworks_udp_get($res, 4 ); ipworks_udp_set($res, 4, $value );
Default Value
''
Remarks
The LocalHost property contains the name of the local host as obtained by the gethostname() system call, or if the user has assigned an IP address, the value of that address.
In multihomed hosts (machines with more than one IP interface) setting LocalHost to the IP address of an interface will make the class initiate connections (or accept in the case of server classs) only through that interface. It is recommended to provide an IP address rather than a hostname when setting this property to ensure the desired interface is used.
If the class is connected, the LocalHost property shows the IP address of the interface through which the connection is made in internet dotted format (aaa.bbb.ccc.ddd). In most cases, this is the address of the local host, except for multihomed hosts (machines with more than one IP interface).
Note: LocalHost is not persistent. You must always set it in code, and never in the property window.
Data Type
String
LocalPort Property (IPWorks_UDP Class)
This property includes the User Datagram Protocol (UDP) port in the local host where UDP binds.
Object Oriented Interface
public function getLocalPort(); public function setLocalPort($value);
Procedural Interface
ipworks_udp_get($res, 5 ); ipworks_udp_set($res, 5, $value );
Default Value
0
Remarks
The LocalPort property must be set before UDP is activated (Active is set to True). This instructs the class to bind to a specific port (or communication endpoint) in the local machine.
Setting it to 0 (default) enables the Transmission Control Protocol (TCP)/IP stack to choose a port at random. The chosen port will be shown by the LocalPort property after the connection is established.
LocalPort cannot be changed once the class is Active. Any attempt to set the LocalPort property when the class is Active will generate an error.
The LocalPort property is useful when trying to connect to services that require a trusted port on the client side.
Data Type
Integer
RemoteHost Property (IPWorks_UDP Class)
This property includes the address of the remote host. Domain names are resolved to IP addresses.
Object Oriented Interface
public function getRemoteHost(); public function setRemoteHost($value);
Procedural Interface
ipworks_udp_get($res, 6 ); ipworks_udp_set($res, 6, $value );
Default Value
''
Remarks
The RemoteHost property specifies the IP address (IP number in dotted internet format) or domain name of the remote host.
If RemoteHost is set to 255.255.255.255, the class broadcasts data on the local subnet.
If the RemoteHost property is set to a domain name, a DNS request is initiated, and upon successful termination of the request, the RemoteHost property is set to the corresponding address. If the search is not successful, an error is returned.
If UseConnection is set to True, the RemoteHost must be set before the class is activated (Active is set to True).
Data Type
String
RemotePort Property (IPWorks_UDP Class)
This property specifies the User Datagram Protocol (UDP) port in the remote host.
Object Oriented Interface
public function getRemotePort(); public function setRemotePort($value);
Procedural Interface
ipworks_udp_get($res, 7 ); ipworks_udp_set($res, 7, $value );
Default Value
0
Remarks
The RemotePort is the UDP port on the RemoteHost to send UDP datagrams to.
A valid port number (a value between 1 and 65535) is required.
If UseConnection is set to True, the RemotePort must be set before the class is activated (Active is set to True).
Data Type
Integer
TimeToLive Property (IPWorks_UDP Class)
This property specifies the maximum number of subnets that a datagram can traverse.
Object Oriented Interface
public function getTimeToLive(); public function setTimeToLive($value);
Procedural Interface
ipworks_udp_get($res, 8 ); ipworks_udp_set($res, 8, $value );
Default Value
0
Remarks
The default value for this property is 0, which tells the class to use the default time-to-live (TTL) value of the underlying Transmission Control Protocol (TCP)/IP subsystem. Depending on the application, you can specify a value between 1 and 255.
Data Type
Integer
Activate Method (IPWorks_UDP Class)
This method enables sending and receiving of data.
Object Oriented Interface
public function doActivate();
Procedural Interface
ipworks_udp_do_activate($res);
Remarks
This method enables sending and receiving of data. When called, the class will create a communication endpoint (socket) that can be used for sending and receiving User Datagram Protocol (UDP) messages. This method must be called before using the class to send and receive data.
If the UseConnection configuration setting is set to true, then a local association (connection) to the remote host is also created.
Config Method (IPWorks_UDP Class)
Sets or retrieves a configuration setting.
Object Oriented Interface
public function doConfig($configurationstring);
Procedural Interface
ipworks_udp_do_config($res, $configurationstring);
Remarks
Config is a generic method available in every class. It is used to set and retrieve configuration settings for the class.
These settings are similar in functionality to properties, but they are rarely used. In order to avoid "polluting" the property namespace of the class, access to these internal properties is provided through the Config method.
To set a configuration setting named PROPERTY, you must call Config("PROPERTY=VALUE"), where VALUE is the value of the setting expressed as a string. For boolean values, use the strings "True", "False", "0", "1", "Yes", or "No" (case does not matter).
To read (query) the value of a configuration setting, you must call Config("PROPERTY"). The value will be returned as a string.
Deactivate Method (IPWorks_UDP Class)
This method disables sending and receive of data.
Object Oriented Interface
public function doDeactivate();
Procedural Interface
ipworks_udp_do_deactivate($res);
Remarks
This method disables sending and receiving of data. When called, the class will destroy the existing socket and disable data communications.
DoEvents Method (IPWorks_UDP Class)
This method processes events from the internal message queue.
Object Oriented Interface
public function doEvents();
Procedural Interface
ipworks_udp_do_doevents($res);
Remarks
When DoEvents is called, the class processes any available events. If no events are available, it waits for a preset period of time, and then returns.
PauseData Method (IPWorks_UDP Class)
This method pauses data reception.
Object Oriented Interface
public function doPauseData();
Procedural Interface
ipworks_udp_do_pausedata($res);
Remarks
This method pauses data reception when called. While data reception is paused, the DataIn event will not fire. Call ProcessData to reenable data reception.
ProcessData Method (IPWorks_UDP Class)
This method reenables data reception after a call to PauseData .
Object Oriented Interface
public function doProcessData();
Procedural Interface
ipworks_udp_do_processdata($res);
Remarks
This method reenables data reception after a previous call to PauseData. When PauseData is called, the DataIn event will not fire. To reenable data reception and allow DataIn to fire, call this method.
Note: This method is used only after previously calling PauseData. It does not need to be called to process incoming data by default.
Reset Method (IPWorks_UDP Class)
This method will reset the class.
Object Oriented Interface
public function doReset();
Procedural Interface
ipworks_udp_do_reset($res);
Remarks
This method will reset the class's properties to their default values.
ResolveRemoteHost Method (IPWorks_UDP Class)
This method resolves the hostname in RemoteHost to an IP address.
Object Oriented Interface
public function doResolveRemoteHost();
Procedural Interface
ipworks_udp_do_resolveremotehost($res);
Remarks
This method resolves the hostname specified by RemoteHost to an IP address. The resolved value is available in the RemoteHost property after this method returns.
In most cases, calling this method is not necessary; the class will resolve the hostname automatically when needed. If DelayHostResolution is true, this method may be called to manually resolve RemoteHost, if desired.
Send Method (IPWorks_UDP Class)
This method sends binary data to the remote host.
Object Oriented Interface
public function doSend($text);
Procedural Interface
ipworks_udp_do_send($res, $text);
Remarks
This method sends the specified binary data to the remote host. To send text, use the SendText method instead.
Example. Send Data:
UDPControl.LocalPort = 8765
UDPControl.RemotePort = 8765
UDPControl.RemoteHost = "HostNameOrIPAddress"
UDPControl.Active = True
UDPControl.SendText("Hello!")
SendBytes Method (IPWorks_UDP Class)
This method sends binary data to the remote host.
Object Oriented Interface
public function doSendBytes($data);
Procedural Interface
ipworks_udp_do_sendbytes($res, $data);
Remarks
This method sends the specified binary data to the remote host. To send text, use the SendText method instead.
Example. Send Data:
UDPControl.LocalPort = 8765
UDPControl.RemotePort = 8765
UDPControl.RemoteHost = "HostNameOrIPAddress"
UDPControl.Active = True
UDPControl.SendText("Hello!")
SendText Method (IPWorks_UDP Class)
This method sends text to the remote host.
Object Oriented Interface
public function doSendText($text);
Procedural Interface
ipworks_udp_do_sendtext($res, $text);
Remarks
This method sends the specified text to the remote host. To send binary data, use the SendBytes method instead.
Example. Send Data:

This event is fired when data are received.
Object Oriented Interface
public function fireDataIn($param);
Procedural Interface
ipworks_udp_register_callback($res, 1, array($this, 'fireDataIn'));
Parameter List
'datagram'
'sourceaddress'
'sourceport'
Remarks
The DataIn event is fired every time a new datagram is received.
Datagram contains the packet as sent by the remote host.
SourceAddress contains the IP number (Internet address) of the remote host, and SourcePort contains the port from which the packet originated.
Note: Events are not re-entrant. Performing time-consuming operations within this event will prevent it from firing again in a timely manner and may affect overall performance.
Error Event (IPWorks_UDP Class)
Fired when information is available about errors during data delivery.
Object Oriented Interface
public function fireError($param);
Procedural Interface
ipworks_udp_register_callback($res, 2, array($this, 'fireError'));

ReadyToSend Event (IPWorks_UDP Class)
This event is fired when the class is ready to send data.
Object Oriented Interface
public function fireReadyToSend($param);
Procedural Interface
ipworks_udp_register_callback($res, 3, array($this, 'fireReadyToSend'));
Parameter List
Remarks
The ReadyToSend event indicates that the underlying Transmission Control Protocol (TCP)/IP subsystem is ready to accept data after a failed Send.
Config Settings (UDP 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.UDP Config Settings
The default value for this setting is False.
Note: This setting is available only in Windows.
The default value is false.
Note: This setting is available only in Windows.
In multihomed hosts (machines with more than one IP interface), setting LocalHost to the value of an interface will make the class initiate connections (or accept in the case of server classs) only through that interface.
If the class is connected, the LocalHost setting shows the IP address of the interface through which the connection is made in internet dotted format (aaa.bbb.ccc.ddd). In most cases, this is the address of the local host, except for multihomed hosts (machines with more than one IP interface).
Setting this to 0 (default) enables the system to choose a port at random. The chosen port will be shown by LocalPort after the connection is established.
LocalPort cannot be changed once a connection is made. Any attempt to set this when a connection is active will generate an error.
This configuration setting is useful when trying to connect to services that require a trusted port on the client side. An example is the remote shell (rsh) service in UNIX systems.
Note: This setting uses the qWAVE API and is available only on Windows 7, Windows Server 2008 R2, and later.
Note: This setting uses the qWAVE API and is available only on Windows Vista and Windows Server 2008 or above.
Note: QOSTrafficType must be set before setting Active to True.
The default value for this setting is False.
Note: This setting is available only in Windows and requires that the winpcap library be installed (or npcap with winpcap compatibility).
Note: This setting is available only in Windows and requires that the winpcap library be installed (or npcap with winpcap compatibility).
The default value for this setting is False.
Socket Config Settings
Note: This option is not valid for User Datagram Protocol (UDP) ports.
Some TCP/IP implementations do not support variable buffer sizes. If that is the case, when the class is activated the InBufferSize reverts to its defined size. The same happens if you attempt to make it too large or too small.
Some TCP/IP implementations do not support variable buffer sizes. If that is the case, when the class is activated the OutBufferSize reverts to its defined size. The same happens if you attempt to make it too large or too small.
