Writing S-Functions

ssSetPWorkValue

Set an element of a block's pointer work vector.

Syntax

• void* ssSetPWorkValue(SimStruct *S, int_T idx, void* pointer)
  

Arguments

S
   SimStruct representing an S-Function block.

idx
   Index of the element to be set

pointer
   New pointer element

Description

Sets the idx element of S's pointer work vector to pointer. The vector consists of elements of type void* and is of length ssGetNumPWork(S). Typically, this vector is initialized in mdlStart or mdlInitializeConditions, updated in mdlUpdate, and used in mdlOutputs. You can use this macro in the simulation loop, mdlInitializeConditions, or mdlStart routines. This macro returns the pointer that it sets.

Example

The following statement

• typedef struct Color_tag {int r; int b; int g;} Color;
  Color* p = malloc(sizeof(Color)); 
  ssSetPWorkValue(s, 0, p);
  

sets the first element of the pointer work vector to a pointer to the allocated Color structure.
