Get argument position for Simulink model port from model-specific C++ encapsulation interface
position = getArgPosition(obj, portName)
position = getArgPosition(obj, portName) gets the position — 1 for first, 2 for second, etc. — of the argument corresponding to a specified Simulink model inport or outport from a specified model-specific C++ encapsulation interface.
| obj | Handle to a model-specific C++ encapsulation interface control object, such as a handle previously returned by obj = RTW.getEncapsulationInterfaceSpecification (modelName). |
| portName | String specifying the name of an inport or outport in your Simulink model. |
| position | Integer specifying the argument position — 1 for first, 2 for second, etc. — for the specified Simulink model port. If no argument exists for the specified port, the function returns 0. |
To view argument positions in the Simulink Configuration Parameters graphical user interface, go to the Interface pane and click the Configure C++ Encapsulation Interface button. This button launches the Configure C++ encapsulation interface dialog box, where you can display and configure the step method for your model class. In the I/O arguments step method view of this dialog box, click the Get Default Configuration button to display step method argument positions. For more information, see Configure the Step Method for Your Model Class in the Embedded Coder documentation.
