Get argument position for Simulink model port from
model-specific C function prototype
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 function prototype.
Inputs
| 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. |
Outputs
| 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. |
Alternatives
Click the Get Default Configuration button
in the Model Interface dialog box to get argument positions. See Model Specific C Prototypes View in
the Real-Time Workshop Embedded Coder documentation.
