Get the sample time of an input port
real_T ssGetInputPortSampleTime(SimStruct *S, int_T inputPortIdx)
A real_T value indicating the sample time of the input port specified by the index inputPortIdx.
Use in any routine (except mdlInitializeSizes) to determine the sample time of an input port. You should use this macro only if you have specified the sample times as port-based. Use ssGetSampleTime to determine the sample time of S-functions that do not use port-based sample times.
