Question

I have an array of 64 bit unsigned integers. Is it possible to assign some pointers of an array in some positions of it. I mean:

array [0] = Integer
array [1] = Integer
array [2] = Pointer to array
array [3] = Pointer to array
array [4] = Integer

Can anybody help me how to do that ?

Answer 1

One way is to turn array into an array of

union {
  uint64_t   intval;
  uintptr_t  ptrval;
};

and work with that.

You will, of course, need some way to know whether a particular element stores an integer or a pointer.
