setReturn

Add return argument to RTW.CImplementation object

Since R2024a

Syntax

setReturn(implementation,arg)

Description

setReturn(implementation,arg) adds the return argument to the RTW.CImplementation object that represents the implementation function specification implementation.

Examples

Specify a Void Return for an Implementation Function

Specify a void return for an implementation function for the Discrete FIR Filter block.

Create a block replacement entry for the Discrete FIR Filter block.

hLib = RTW.TflTable;

entry = RTW.TflBlockEntry;
entry.Key = 'DiscreteFir';

Create the RTW.CImplementation object that represents the implementation function. Specify the name and header file for the function.

impl = RTW.CImplementation;
impl.Name = 'arm_fir_init';
impl.HeaderFile = 'arm_math.h';

Add an input argument to the implementation object.

arg = getTflArgFromString(hLib, 'u1', 'uint16');
addArgument(impl, arg);

Specify a void return for the implementation object.

arg = hLib.getTflArgFromString('void','void');
arg.IOType = 'RTW_IO_OUTPUT';
setReturn(impl,arg); 

Add the implementation function to the block replacement entry as the replacement initialization function.

addImplementation(entry, 'initialize', impl);

Input Arguments

implementation — Implementation function

RTW.CImplementation object

Implementation function, specified as an RTW.CImplementation object.

arg — Implementation function return argument

argument handle

Implementation function return argument, specified as a handle such as the argument handle returned by the function getTflArgFromString.

Example: getTflArgFromString('void','void');
