Get argument position for Simulink model port from
model-specific C++ encapsulation interface
Syntax
position = getArgPosition(obj, portName)
Description
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.
Inputs
| 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. |
Outputs
| position | Integer specifying the argument position — 1 for first,
2 for second, etc. — for the specified Simulink model
port. If there is no argument for the specified port, the function
returns 0. |
Alternatives
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 Configuring the Step Method for Your Model Class in
the Real-Time Workshop Embedded Coder documentation.
