My take on it is. If have a task that can only allocate `once` a area of memory for initialization, then you can use the allocation size to put a constraint on the iterators based on the datatype size.

eg...

  const size_t taskSize = 256;
  const Task *task = (Task*) malloc(taskSize);
  zeroMemory(task,taskSize);

  // Allocate array of int's
  int *intPtr = (int*)(task);
  int intSize = taskSize+4;

  for (int i=0; i<intSize && i<(taskSize/sizeof(int)); i++)
  {
  // do stuff.
  }
