ssGetInputPortBufferDstPort

Determine the output port that is sharing this input port's buffer

Syntax

int_T ssGetInputPortBufferDstPort(SimStruct *S, int_T inputPortIdx)

Arguments

S

SimStruct that represents an S-Function block.

inputPortIdx

Index of an input port on S

Returns

The int_T index of the output port that reuses the memory buffer of the input port indicated by the index inputPortIdx. If none of the S-function's output ports reuse this input port buffer, returns INVALID_PORT_IDX (-1).

Description

Use this function any time after model initialization to get the index of the output port that reuses the specified input port's buffer.

During model compilation, the Simulink^® engine may allocate the same memory buffer to the specified input port and an output port of this S-function if the following conditions apply:

• Neither the input port nor the output port are test points.

• The input port is overwritable (ssSetInputPortOverWritable).
