GetValueForSimulation Macro

Returns a model-based value to return from a function or attribute value when simulating.

#define GetValueForSimulation(Vi, pValueOut, ...)

Parameters

Vi: [in] ViSession handle for the driver session.
pValueOut: [out] Simulated value chosen based from those supplied in the model-specific list of values in the variable argument parameter.
... (variable arguments): [in] A variable argument list of model-value pairs. The function returns in the pValueOut parameter a value from this list based on matching the connected instrument model with one of the entries in this list.

Example

The following example demonstrates use of the GetValueForSimulation function.

C++

ViStatus _VI_FUNC acme4321_get_BANDWIDTH(ViSession Vi, ViConstString RepCapIdentifier, ViReal64* AttributeValue)
{
    // ...

    if (SimulationEnabled(Vi))
    {
        if (!cacheManager.GetCachedValue(AttributeValue))
        {
            // The entries below indicate which values should be returned based upon the instrument model 
            // being simulated.  The entry with no model specified (the one with value 1.0E9) will be chosen
            // if the model is something other than ModelA, ModelB, or ModelC.
            // 
            GetValueForSimulation(
                Vi, AttributeValue,
                { 1.0E9 },              
                { "ModelA", 2.0E9 },
                { "ModelB", 5.0E9 },
                { "ModelC", 7.0E9 },
            );
        }

        return VI_SUCCESS;
    }    

    // ...
