DataIn Event

Fired when new ICMP messages come in.

Syntax

 virtual int FireDataIn(ICMPPortDataInEventParams *e);

 
 typedef struct {

  int MessageType;
  int MessageSubType;
  char* MessageData;
  int Checksum;
  char* SourceAddress;

  int lenMessageData;
  int reserved;

 } ICMPPortDataInEventParams;

Remarks

The MessageType parameter shows the type of the ICMP messages and MessageSubType its subtype.

The MessageData parameter contains the message data.

The Checksum parameter is True or False depending on the ICMP checksum check on the message.

Note that events are not re-entrant. Performing time consuming operations within this event will prevent it from firing again in a timely manner and may impact overall performance.
