ssSetInputPortRequiredContiguous - Specify that the signal elements entering a port must be contiguous

Syntax

void ssSetInputPortRequiredContiguous(SimStruct *S, int_T port, 
 int_T flag)

Arguments

S

SimStruct representing an S-Function block.

port

Index of an input port.

flag

True (1) if signal elements must be contiguous.

Description

Specifies that the signal elements entering the specified port must occupy contiguous areas of memory. This allows a method to access the elements of the signal simply by incrementing the signal pointer returned by ssGetInputPortSignal. The S-function can set the value of this attribute as early as in the mdlInitializeSizes method and at the latest in the mdlSetWorkWidths method.

Note   The default setting for this flag is false (0). Hence, the default method for accessing the input signals is ssGetInputSignalPtrs.

Languages

C, C++

Example

See the S-function matlabroot/toolbox/simulink/simdemos/simfeatures/src/sfun_io_handling2.c used in sfcndemo_io_handling.mdl.
