Get argument position for Simulink model port from model-specific C function prototype
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 function prototype.
| obj | Handle to a model-specific C prototype function control object previously returned by obj = RTW.getFunctionSpecification (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 is found for the specified port, the function returns 0. |
Click the Get Default Configuration button in the Model Interface dialog box to get argument positions. See Model Specific C Prototypes View in the Embedded Coder documentation.
