ssSetInputPortOverWritable (Writing S-Functions)

Specify whether an input port can be overwritten.

C Syntax

void ssSetInputPortOverWritable(SimStruct *S, int_T port, int_T 
isOverwritable)

Ada Syntax

procedure ssSetInputPortOverWritable(S : in SimStruct; port : in 
Integer := 0; isOverwritable : in Boolean);

Arguments
S
SimStruct representing an S-function block or a Simulink model.

port
Index of the input port whose overwritability is being set.

isOverwritable

Value specifying whether port is overwritable.

Description

Use in mdlInitializeSizes (after ssSetNumInputPorts) to specify whether the input port is overwritable by an output port. The default is isOverwritable=0, which means that the input port does not share memory with an output port. When isOverwritable=1, the input port shares memory with an output port.

Note ssSetInputPortReusable and ssSetOutputPortReusable must both be set to 0, meaning that neither port involved can have global and persistent memory.
