Valid for: CANoe DE • CANoe4SW DE

Function Syntax

• long SecurityLocalUnregisterApplicationProtocol(char applicationProtocolUserDefinedId[]) // form 1
• long SecurityLocalUnregisterApplicationProtocol(char applicationProtocolUserDefinedId[], dword vLanId) // form 2

Description

Unregisters the reception of the application protocol with the specified User Defined Id. The node will no longer receive this application protocol and the callbacks OnSecurityLocalApplicationProtocolRxFinished or OnSecurityLocalApplicationProtocolTxFinished will also no longer be called. The call of SecurityLocalAllowNetworkWideRegistrations is a precondition for using this function.

Parameters

—

Return Values

• 1: Success.
• -1: The specified applicationProtocolUserDefinedId has not been registered.
• -2: SecurityLocalAllowNetworkWideRegistrations must be called before using this function.
• -5: The specified applicationProtocolUserDefinedId has not been registered on the same VLAN.
• -6: The Security Manager does not support this function. (Security Manager V2.3.9 or later required).
• -10: Security is not usable. Reasons can be: Security Manager version is too old. Tool Version is too old. Security Profile is invalid.

Example

// Implement this in an Observer-Node to receive callbacks of Application-Protocol for real ECUs
on preStart
{
  long result = 0;
  result = SecurityLocalAllowNetworkWideRegistrations();
  Write("The call of SecurityLocalAllowNetworkWideRegistrations returned %i", result);
}

on start
{
  dword result = 0;
  result = SecurityLocalRegisterApplicationProtocol("APPLICATIONPROTOCOLNAME",10);
  Write("SecurityLocalRegisterApplicationProtocol to register to APPLICATIONPROTOCOLNAME on VLAN 10 returned %i", result);
}

void OnLocalSecurityApplicationProtocolRxFinished(char applicationProtocolName[], byte payload[], dword payloadLength, dword result)
{
  if(strncmp(applicationProtocolName,"APPLICATIONPROTOCOLNAME",23) == 0)
  {
    write("Received Application Protocol %s", applicationProtocolName);
  }
}

on stopMeasurement
{
  dword result = 0;
  result = SecurityLocalUnregisterApplicationProtocol("APPLICATIONPROTOCOLNAME",10);
  Write("SecurityLocalUnregisterApplicationProtocol to unregister from APPLICATIONPROTOCOLNAME on VLAN 10 returned %i", result);
