Get an element of a block's integer work vector
int_T ssGetIWorkValue(SimStruct *S, int_T idx)
The int_T value stored in the idx element of the integer work vector for this S-function. Returns NULL if no value was assigned into the idx element of the IWork vector.
Use this macro in the simulation loop, mdlInitializeConditions, or mdlStart routines to obtain an element of the IWork vector. 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.
The following statement
int_T v = ssGetIWorkValue(S, 0);
is equivalent to
int_T* wv = ssGetIWork(S); int_T v = wv;
