The CPosPassThru and CRendererPosPassThru classes are helper objects that pass seeking commands upstream, so the CSeekingPassThru class is a helper object for creating helper objects. It is not necessary to use this class directly. Instead, use the CreatePosPassThru function, which handles all...

To create a FunctionPortSpecification object for a selected C Caller block in a model, type in the command line: myCCallerConfigObj = get_param(gcb, 'FunctionPortSpecification') myCCallerConfigObj = FunctionPortSpecification with properties: CPrototype: 'real_T add(real_T u1, real_T u2);'...
