# SIMCONNECT_DATA_MARKERSTATE<no value>
The **SIMCONNECT\_DATA\_MARKERSTATE** structure is used to help graphically link flight model data with the graphics model.

 

##### Syntax

``` cpp
struct SIMCONNECT_DATA_MARKERSTATE{
    char  szMarkerName[64];
    DWORD  dwMarkerState;
    };
```

 

##### Members

##### Remarks

The `SimConnect_AddToDataDefinition` call can be used to add a `SIMCONNECT_DATA_MARKERSTATE` structure to a data definition. Use of this call and structure is to help determine that points specified in the flight model of an aircraft match the graphics model for that aircraft, by turning on the specified marker lights. A SimConnect client created to do this becomes a tool to aid to the accurate development of aircraft models, rather than an add-on that an end user might run.

 

This structure can only be used as input, it cannot be used as part of a data request.
