OnAREthProcessTxARPDU

Valid for: CANoe DE • CANoe4SW DE

​
Function Syntax

  • long OnAREthProcessTxARPDU(dword sourceAddress, dword sourcePort, dword destinationAddress, dword destinationPort, dword length, char buffer[], dword headerID); // form 1 is deprecated, use form 3
  • long OnAREthProcessTxARPDU(dword sourceAddress, dword sourcePort, dword destinationAddress, dword destinationPort, dword length, byte buffer[], dword headerID); // form 2 is deprecated, use form 4
  • long OnAREthProcessTxARPDU(IP_Endpoint sourceEndpoint, IP_Endpoint destinationEndpoint, dword length, char buffer[], dword header_id); // form 3
  • long OnAREthProcessTxARPDU(IP_Endpoint sourceEndpoint, IP_Endpoint destinationEndpoint, dword length, byte buffer[], dword header_id); // form 4
  • long OnAREthProcessTxARPDU(IP_Endpoint sourceEndpoint, IP_Endpoint destinationEndpoint, dword length, char buffer[]); // form 5
  • long OnAREthProcessTxARPDU(IP_Endpoint sourceEndpoint, IP_Endpoint destinationEndpoint, dword length, byte buffer[]); // form 6

​
Description

This callback is called before the interaction layer wants to send an AUTOSAR PDU. For PDUs with headers, form 3 or form 4 must be used, for headerless PDUs form 5 or form 6. This makes it possible to suppress the transmission.

​
Parameters

  • sourceAddress: IPv4 address of the local application endpoint.
  • sourcePort: UDP or TCP port of the local application endpoint.
  • sourceEndpoint: Endpoint of the local application endpoint.
  • destinationAddress: IPv4 address of the target.
  • destinationPort: UDP or TCP port of the target.
  • destinationEndpoint: Endpoint of the target.
  • length: Length of the data.
  • buffer: Data to transmit.
  • headerId: ID which is to be written in the header before the AUTOSAR PDU.

​
Return Values

The AUTOSAR PDU is sent by the interaction layer, if the callback sends back 1. Otherwise the transmission is suppressed.

​
Example

long OnAREthProcessTxARPDU(IP_Endpoint sourceEndpoint, IP_Endpoint destinationEndpoint, dword length, byte buffer[], dword header_id)
{ 
    // The AUTOSAR PDU is sent by the interaction layer, if the callback sends back 1
    IP_Endpoint UDP:192.168.1.10:4242 endpoint;

    if (sourceEndpoint.MatchesEndPoint(endpoint) == 1)
    {
        return 1; // send
    }
    else
    {
        return 0; // do not send
    }
}
