setArgCategory - Class: RTW.ModelSpecificCPrototype
Package: RTW

Set argument category for Simulink model port in model-specific C function prototype

Syntax

setArgCategory(obj, portName, category)

Description

setArgCategory(obj, portName, category) sets the category, 'Value' or 'Pointer', of the argument corresponding to a specified Simulink model inport or outport in a specified model-specific C function prototype.

Input Arguments

obj Handle to a model-specific C prototype function control object previously returned by obj = RTW.ModelSpecificCPrototype or obj = RTW.getFunctionSpecification(modelName).

portName String specifying the unqualified name of an inport or outport in your Simulink model.

category

String specifying the argument category, 'Value' or 'Pointer', that you set for the specified Simulink model port.

Note If you change the argument category for an outport from 'Pointer' to 'Value', it causes the argument to move to the first argument position when you call RTW.ModelSpecificCPrototype.attachToModel or RTW.ModelSpecificCPrototype.runValidation.

Alternatives

Use the Step function arguments table in the Model Interface dialog box to specify argument categories. See Model Specific C Prototypes View in the Embedded Coder documentation.
