TestData Parameter - LabWindows/CVI Call Parameters
TestData Parameter
The TestData data type was used in TestStand 2.0. x with the C/CVI Standard Prototype Adapter, which required you to use a specific prototype. This parameter type represents a C structure that contains input and output data for the code module .
Note
Use this parameter for compatibility purposes only. National Instruments recommends that you use the new LabWindows/CVI code module templates.
The Pass Sequence Context option specifies whether the LabWindows/CVI Adapter passes a sequence context to the code module. Enable this option when you want to call the TestStand API in the code module or when the code module must pass the sequence context to another function.
