Determine the output port that is sharing this input port's buffer
int_T ssGetInputPortBufferDstPort(SimStruct *S, int_T inputPortIdx)
SSimStruct representing an S-Function block.
inputPortIdxIndex of an input port on S
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).
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
