Description

TSocketErrorEvent is the type for event handlers that respond when a Windows socket reports an error.

The Sender parameter is the socket component that encountered the error.

The Socket parameter is the TCustomWinSocket object that receives the error notification.

The ErrorCode parameter is the error code returned by the Windows socket API call. Changing this to 0 within an error handler prevents an exception from being raised.
