ssSetOutputPortOverwritesInputPort

Specify whether an output port can share its memory buffer with an input port

Syntax

void ssSetOutputPortOverwritesInputPort(SimStruct *S, int_T outIdx,
 int_T inIdx)

Arguments

S

SimStruct that represents an S-Function block.

outIdx

Index of the output port.

inIdx

Index of the input port.

Description

The argument inIdx tells the Simulink^® engine which input port of S can share its memory with the output port specified by outIdx. inIdx can have the following values:

• Index of an input port of S that can share its memory with the specified output port.

  You must use ssSetInputPortOverWritable to tell the engine that the specified input port can share its memory with an output port.

• OVERWRITE_INPUT_ANY

  The output port can share its memory with any input port.

• OVERWRITE_INPUT_NONE

  The output port must have its own memory buffer.
