SimConnect_AddToFacilityDefinition

The SimConnect_AddToFacilityDefinition function is used to create a facility data definition.

 

Syntax
HRESULT SimConnect_AddToFacilityDefinition(
    HANDLE hSimConnect,
    SIMCONNECT_DATA_DEFINITION_ID DefineID,
    const char * FieldName
    );

 

Parameters
Parameter Description Type
hSimConnect Handle to a SimConnect object. Integer
DefineID Specifies the ID of the client defined data definition Integer
FieldName Specifies the client defined request ID. This will be returned along with the data. Integer

 

Return Values

The function returns an HRESULT. Possible values include, but are not limited to, those in the following table.

Return value Description
S_OK The function succeeded.
E_FAIL The function failed.

 

It is also possible that the following Exception IDs will be received:

  • SIMCONNECT_EXCEPTION_UNRECOGNIZED_ID - An invalid DefineID has been supplied.
  • SIMCONNECT_EXCEPTION_DATA_ERROR - An invalid FieldName has been supplied.

 

Remarks

This is used to add a new field to a client defined object definition in order to retrieve information. Using this function will require multiple calls and these calls will need to be formatted in a very specific way, initially using one of the four available entry points:

Each entry point will need to be prefixed with "OPEN " before any data is requested, and then prefixed with "CLOSED " to end the data retrieval, and this format works for the different child members of these entry points. For example:

SimConnect_AddToFacilityDefinition(hSimConnect, FACILITY_DATA_DEF_AIRPORT, "OPEN AIRPORT");
// Request further airport data
SimConnect_AddToFacilityDefinition(hSimConnect, FACILITY_DATA_DEF_AIRPORT, "CLOSE AIRPORT");
SimConnect_AddToFacilityDefinition(hSimConnect, FACILITY_DATA_DEF_AIRPORT, "OPEN NDB");
// Request further NDB data
SimConnect_AddToFacilityDefinition(hSimConnect, FACILITY_DATA_DEF_AIRPORT, "CLOSE NDB");
// etc...

Essentially, for every member that you open you must have a corresponding close, otherwise you will have an error. Note too that after defining the data that you want to retrieve, you will need to call SimConnect_RequestFacilityData to finalise and send the request.

 

At the bottom of this page you can find information on each of the entry points and the different members and children that they can contain.

 

Note that results may be filtered using the SimConnect_AddFacilityDataDefinitionFilter function, ensuring that you receive less data, and that the data is relevant.

 

Example
SIMCONNECT_DATA_DEFINITION_ID FACILITY_DATA_DEF_AIRPORT = 123;
{
    // Entry point will be an Airport
    SimConnect_AddToFacilityDefinition(hSimConnect, FACILITY_DATA_DEF_AIRPORT, "OPEN AIRPORT");
	
    // Add some airport members
    SimConnect_AddToFacilityDefinition(hSimConnect, FACILITY_DATA_DEF_AIRPORT, "A");
    SimConnect_AddToFacilityDefinition(hSimConnect, FACILITY_DATA_DEF_AIRPORT, "B");
    SimConnect_AddToFacilityDefinition(hSimConnect, FACILITY_DATA_DEF_AIRPORT, "C");
    
    // Runway is a child of Airport, so we can request them in Airport FacilityDataDefinition
    SimConnect_AddToFacilityDefinition(hSimConnect, FACILITY_DATA_DEF_AIRPORT, "OPEN RUNWAY");
	
    // Add some runway members
    SimConnect_AddToFacilityDefinition(hSimConnect, FACILITY_DATA_DEF_AIRPORT, "a");
    SimConnect_AddToFacilityDefinition(hSimConnect, FACILITY_DATA_DEF_AIRPORT, "b");
    
    // We requested every thing we want about runway, so "close" it to get back to Airport Definition
    SimConnect_AddToFacilityDefinition(hSimConnect, FACILITY_DATA_DEF_AIRPORT, "CLOSE RUNWAY");
    
    // We requested every thing we want about airport, so "close" it.
    SimConnect_AddToFacilityDefinition(hSimConnect, FACILITY_DATA_DEF_AIRPORT, "CLOSE AIRPORT");
    
    // Request data from Airport LFPG which will follow the format defined earlier.
    SimConnect_RequestFacilityData(hSimConnect, FACILITY_DATA_DEF_AIRPORT, 123, "LFPG");
}

In the example given above, we have created a facility data definition which will request members "A", "B", and "C" of an airport and members "a" and "b" of each runway for the airport with ICAO "LFPG" (which has four runways). You should receive back from this the following:

  • A message about Airport data [A, B, C]
  • 4 messages about runway data [a, b]

So, imagine we complete an example request like the one above and each runway has a child with members "1", "2", and "3". In that case you would receive back the following data:

[A, B, C] [a, b] [1, 2, 3] [a, b] [1, 2, 3] [a, b] [1, 2, 3] [a, b] [1, 2, 3]
