Arguments

Returns

Theint_Tindex of the output port that reuses the memory buffer of the input port indicated by the indexinputPortIdx. If none of the S-function's output ports reuse this input port buffer, returnsINVALID_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:
