ssSetInputPortOptimOpts

Specify reusability of the memory allocated to the input port of an S-function

Syntax

void ssSetInputPortOptimOpts(SimStruct *S, int_T port, uint_T val)

Arguments

S

SimStruct representing an S-Function block.

port

Index of an input port of S.

val

Reusability of port. Permissible values are

  • SS_NOT_REUSABLE_AND_GLOBAL

  • SS_REUSABLE_AND_LOCAL

  • SS_REUSABLE_AND_GLOBAL

  • SS_NOT_REUSABLE_AND_LOCAL

Description

Use this macro to specify the reusability and scope of the memory allocated to an S-function input port. The reusability indicates if the memory associated with the input port can be overwritten, or not. You must indicate an input port is reusable if you use the ssSetInputPortOverWritable macro to specify the input port's memory can be overwritten by one of the output ports.

The Simulink® engine disregards the memory scope setting, instead treating all S-function ports as global during simulation.
