Use pointers in simulink

Hello,

I would like to model on Simulink the code in C below, but as you see a pointer is used, this function modifies the value of the memory address, how can I model that, knowing that behind the goal is to regenerate a code using embedded coding?

thanks

void ModifyValue(uint16 Arg1, uint16 *Arg2)

{

{

*Arg2= 5;

}

return (void);

}

Hi,

You can perform this using following method.

1. Create a Simulink function with input and output arguments
2. Right click the block and navigate to C/C++ code --> C/C++ Function Interface
3. Configure C/C++ Return Argument to Void, which modifies all the output arguments defined in simulink function to pointer

Please refer to this sample model if not clear

Thanks.
