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 1, meaning that neither port involved can have global and persistent memory.
