AREthAddEvent

Valid for: CANoe DE • CANoe4SW DE

​
Function Syntax

dword AREthAddEvent( dword psiHandle, dword eventId, char onPrepareEventCallback[] );

​
Description

This function adds an Event to a Provided Service Instance that was created by AREthCreateProvidedServiceInstance. AREthTriggerEvent is used to trigger sending of the Event. Then, the CAPL Callback function <OnAREthPrepareEvent> is called, and the application has the opportunity to change or update the values of the SOME/IP Event. An Event can be removed again using the AREthRemoveEvent function.

​
Parameters

  • psiHandle: Handle of the Provided-Service Instance
  • eventId: Identifier of the Event
  • onPrepareEventCallback: Name of the CAPL function, see CAPL callback <OnAREthPrepareEvent>

​
Return Values

  • 0: An error occurred. The error can be evaluated using the AREthGetLastError function.
  • >0: Handle of the created Event

​
Example

void Initialize()
{
  dword aep; // Application Endpoint handle
  dword psi; // provided service handle
  dword peg; // provided Eventgroup handle
  dword pev; // provided Event handle

  // open Application Endpoint
  aep = AREthOpenLocalApplicationEndpoint(17, 50002);

  // create Service Instance
  psi = AREthCreateProvidedServiceInstance(aep,10,1);

  // create Eventgroup
  peg = AREthAddProvidedEventGroup(psi,1);

  // create Event and add Event to Eventgroup
  pev = AREthAddEvent(psi, 1, "OnPrepareEvent1");
  AREthAddEventToEventgroup(peg, pev);

  // ensure that Event is sent cyclically
  AREthSetProperty(pev,"CycleTimeMs",1000);
}

void OnPrepareEvent1(dword eventHandle, dword messageHandle)
{
  // this function is called before the Event is sent. Parameters can be specified here.
