I'm not sure about a natural way, but the following should suffice:

typedef void *(*NextStateFun)();

static void *state1();
static void *state2();
static void *state3();

void *state1() { return (void *)state2; }
void *state2() { return (void *)state3; }
void *state3() { return NULL; }
void * const initial_state = (void *)state1;
.
.
.
    void *state = initial_state;
  
    while (state) { state = (*(NextStateFun)state)(); }
