I\'m having some trouble create a linkedlist in reverse order from a given linkedlist.

I come from a java background, and just started doing some C++.

Can yo

  #include 
  /*
      this is a generic (structure agnostic) routine for reversing a singly linked list.
      1st argument is the memory address the structure is located at, and
      2nd argument is the memory address to this particular structure's NEXT member.

  void *rsll(void *struct_address, void *next_address /*(void **)*/)
  {
    uint32_t offset, holder;
    offset = next_address - struct_address;

    void **p = struct_address, *progress = NULL;
    while(p)
    {
      void *b;
      holder = (uint32_t)p;
      holder += offset;
      p = (void**)holder; //&(N->next)
      b = *p; //(N->next)
      *p = progress; //(N->next)
      holder = (uint32_t)p;
      holder -= offset;
      p = (void**)holder; //N
      progress = p;
      p = b;
    }
    return progress;

  #include

    struct list_t

      int integer;
      struct list_t *next;

    struct list_t d = {40,NULL},
                  c = {30,&d},

    struct list_t *list;
    list = &a;
    list = rsll(list,&(list->next));
    while(list)
    {
      printf("%d\n",list->integer);
      list = list->next;
    }
    return 0;
