GetPDUsTPTCPSrcPort

Syntax

long GetPDUsTPTCPSrcPort(this, dword &tcpSourcePort);

Function

This function can only be used within aon PDUhandler. If the PDU was received via TCP, with this function the TCP source address can be requested.

Parameters

this Handle to the currently handled (received) PDU object.

tcpDestinationPort

TCP source port.

Return Values

0: Data access successful.

-1: Wrong bus type.

-2: The requested information was not available. Most probably the PDU was not received by a TCP layer.

-3: The PDU object is invalid.

-4: PDU is not of RX type.

-5: Parameter too small (e.g. array has too less bytes)

-6: Message or PDU is not available (any more)
