Hi all,

   There may be an issue  in blow function when deleted the node is the first one, that mean n->prev is NULL….., similarly, same issue as the last one node is deleted.

LIST_INLINE void

rem_node(node *n)

{

  node *z = n->prev;

  node *x = n->next;

   z->next = x;

   x->prev = z;

   n->next = NULL;

   n->prev = NULL;

}

Thanks
