ssSetNumIWork

Specify the size of a block's integer work vector

Syntax

void ssSetNumIWork(SimStruct *S, int_T nIWork)

Arguments

S

SimStruct representing an S-Function block.

nIWork

Number of elements in the integer work vector.

Description

Use in mdlInitializeSizes to specify the number of int_T work vector elements as 0, a positive integer, or DYNAMICALLY_SIZED. If you specify DYNAMICALLY_SIZED, you can specify the true (positive integer) width in mdlSetWorkWidths; otherwise, the width used is the width of the signal passing through the block. The elements of the IWork vector are initialized to NULL until values are assigned using ssSetIWorkValue or via the pointer obtained fromssGetIWork.

Languages

C, C++

Example

See the S-function sfun_multirate.c used in sfcndemo_sfun_multirate.
