Get the address of a contiguous signal entering an input port.

Syntax

Arguments

S
   SimStruct representing an S-Function block.

inputPortIdx
   Index of port whose sample time is required.

Description

Returns the address of the specified input port. A method should use this macro only if mdlInitializeSizes has specified that the elements of the input signal be contiguous, using ssSetInputPortRequiredContiguous.

Languages

C, C++

Example

The following code demonstrates the use of ssGetInputPortSignal.

If you know that the inputs are always real_T signals, the ssGetInputPortSignal line in the above code snippet would be
