AREthSetValueString

Valid for: CANoe DE • CANoe4SW DE

Function Syntax

long AREthSetValueString( dword objectHandle, char valuePath[], char value[] ); // form 1
long AREthSetValueString( dword objectHandle, char valuePath[], char value[], long valueLength); // form 2

Description

This function can be used to set a string in the object specified in the objectHandle parameter. Enum data types can be set with one of their symbolic values using this function.

Note

• At present, only the basic A_ASCIISTRING data type is supported.
• 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:

  • Messages
  • Fields
  • Method calls: Handle to a method call that was created with AREthCreateMethodCall.

• valuePath: Path of the value to be set. For specification of complex paths, a corresponding syntax must be adhered to.

• value: New value (this string must be specified as null-terminated string). See BOM in SOME/IP UTF8 and UTF16 strings.

• valueLength: Length of the input string in characters.

Return Values

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

Example

In this example, it is assumed that a service with ID 10 (instance ID 1) is contained in the FIBEX database that is assigned to the CANoe configuration. The service provides an Event that transfers in the structured parameter param 1 the date Error_Message.

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 "Error_Message" of struct "param1"
  AREthSetValueString(messageHandle,"param1.Error_Message","Error Text");
}
