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 that represents 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 ssGetInputPortSignalPtrs.

Languages

C, C++

Examples

See the S-function sfun_io_handling2.c used in sfcndemo_io_handling.
