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 representing 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:
