Writing S-Functions

ssGetIWorkValue

Get an element of a block's integer work vector.

Syntax

• int_T ssGetIWorkValue(SimStruct *S, int_T idx)
  

Arguments

S
   SimStruct representing an S-Function block.

idx
   Index of the element returned by this function

Description

Returns the idx element of the the integer vector used by the block represented by S. The vector consists of elements of type int_T and is of length ssGetNumIWork(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.

Example

The following statement

• int_T v = ssGetIWorkValue(s, 0);
  
  

is equivalent to

• int_T* wv = ssGetIWork(s);
  int_T v = wv[0];
