ssSetNumPWork

Specify the size of a block's pointer work vector

Syntax

int_T ssSetNumPWork(SimStruct *S, int_T nPWork)

Arguments

S

SimStruct representing an S-Function block.

nPWork

Number of elements to be allocated to the pointer work vector of the block represented by S.

Returns

The number of elements specified by nPWork, or -1 if DYNAMICALLY_SIZED.

Description

Use in mdlInitializeSizes to specify the number of pointer (void *) 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 pointer vector are initialized to NULL until values are assigned using ssSetPWorkValue or via the pointer obtained fromssGetPWork.

Languages
