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
C, C++
Example
See the S-function matlabroot/toolbox/simulink/simdemos/simfeatures/src/sfun_rtwdwork.c used
in sfcndemo_sfun_rtwdwork.mdl.
