ssSetPWorkValue (Writing S-Functions)

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.
