DataIn Event

Fired when data is received.

Syntax

typedef void __fastcall (__closure *TipwMCastDataInEvent)(System::TObject* Sender, TipwMCastDataInEventParams *e);



__property TipwMCastDataInEvent OnDataIn = {read=FOnDataIn, write=FOnDataIn};



typedef struct {

     String Datagram;
     String SourceAddress;
     int SourcePort;
} TipwMCastDataInEventParams;

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 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.
