TcpAbort

Use the procedure shown in Figure 1 to shut down a specific connection immediately. Data sent by your application on the abended connection might be lost. TCP sends a reset packet to notify the foreign host that you have abended the connection, but there is no guarantee that the reset will be received by the foreign host.

Figure 1. TcpAbort example

   procedure TcpAbort
            (
                 Connection: ConnectionType;
        var    ReturnCode: integer
            );
            external;
