GetPDUsTPIPv6SrcAddr

CAPL Functions » General » Function Overview » GetPDUsTPIPv6SrcAddr

​
Tool Availability

Valid for: CANoe DE • CANoe4SW DE

​
Function Syntax

long GetPDUsTPIPv6SrcAddr(this, byte IPv6SourceAddress[]);

​
Description

This function can only be used within a on PDU handler. If the PDU was received via IPv6, with this function the IPv6 source address can be requested.

​
Parameters

  • this: Handle to the currently handled (received) PDU object.
  • IPv6SourceAddress: IPv6 source address as 16 byte array.

​
Return Values

  • 0: Data access successful.
  • -1: Wrong bus system.
  • -2: The requested information was not available. Most probably the PDU was not received by an IPv6 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)

​
Example

on PDU engineDataPDU
{
  dword srcPort, dstPort;
  byte srcAddr[16], dstAddr[16];
  char srcAddrAsString[40], dstAddrAsString[40];

  if (GetPDUsTPIPv6SrcAddr(this, srcAddr)==0
      && GetPDUsTPIPv6DstAddr(this, dstAddr)==0)
  {
    IpGetAddressAsString(srcAddr, srcAddrAsString, elcount(srcAddrAsString));
    IpGetAddressAsString(dstAddr, dstAddrAsString, elcount(dstAddrAsString));

    if(GetPDUsTPUDPSrcPort(this, srcPort)==0
       && GetPDUsTPUDPDstPort(this, dstPort)==0)
    {
      write("PDU received by UDP from %s:%u to %s:%u", srcAddrAsString, srcPort, dstAddrAsString, dstPort);
    }

    if (GetPDUsTPTCPSrcPort(this, srcPort)==0
        && GetPDUsTPTCPDstPort(this, dstPort)==0)
    {
      write("PDU received by TCP from %s:%u to %s:%u", srcAddrAsString, srcPort, dstAddrAsString, dstPort);
    }
  }
