​
Function Syntax

long AREthSetValueDWord( dword objectHandle, char valuePath[], dword value );

​
Description

This function can be used to set a raw value in the object specified in the objectHandle parameter. The value is accessed in this case via symbolic access paths. Note
  • A corresponding syntax must be adhered to for specifying the access paths. The access path results from the database description of the value to be read (see also Syntax for Database-based Access Paths).
  • The content of a Service Discovery message can also be read out with this function. Here, the value is accessed via a predefined access path (see also Syntax for Predefined SD Access Paths).

​
Parameters

  • objectHandle: Handle to a AUTOSAR Eth IL object, which must be completely described in the AUTOSAR database. The following objects are supported:
  • valuePath: Access path of the value to be set.
  • value: Raw Value

​
Return Values

  • 0: The function was successfully executed
  • >0: Error code

​
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.
  // set parameter "value1" of struct "param1"
  AREthSetValueDWord(messageHandle,"param1.value1",7);
