Build and send a UDP error message.

procedure SendError(UDPBase: TIdUDPBase; APeerIP: string; const APort: Integer; const ErrNumber: Word; ErrorString: string); overload;
procedure SendError(UDPClient: TIdUDPClient; const ErrNumber: Word; ErrorString: string); overload;
procedure SendError(UDPBase: TIdUDPBase; APeerIP: string; const APort: Integer; E: Exception); overload;
procedure SendError(UDPClient: TIdUDPClient; E: Exception); overload;

UDP descendant generating the exception.

IP address of the peer connection.

Port number of the peer connection.

Error number for the message.

Error text for the message.

UDP client generating the exception.

Exception which should be written in the message.

SendError is an overloaded method used to construct and send UDP protocol error messages. A UDP error message normally contains the error number and text as specified in ErrNumber and ErrorString.

When the Exception variant is used, the text of the error message will contain Exception.Message.

When the TIdUDPClient variant is used, the Host and Port properties of UDPClient are used to send the error message.
