LIST: Additional macros for iteration over the list

[wmdlr]

We propose to include in qblist.h the following macros:

/**

• Iterate over list of given type safe against removal of list entry
• @param pos: the type * to use as a loop cursor.
• @param n: another type * to use as temporary storage
• @param head: the head for your list.
• @param member: the name of the list_struct within the struct.
  _/
  #define qb_list_for_each_entry_safe(pos, n, head, member)
  for (pos = qb_list_entry((head)->next, typeof(_pos), member),
  n = qb_list_entry(pos->member.next, typeof(_pos), member);
  &pos->member != (head);
  pos = n, n = qb_list_entry(n->member.next, typeof(_n), member))

/**

• Iterate backwards over list safe against removal
• @param pos: the type * to use as a loop cursor.
• @param n: another type * to use as temporary storage
• @param head: the head for your list.
• @param member: the name of the list_struct within the struct.
  _/
  #define qb_list_for_each_entry_safe_reverse(pos, n, head, member)
  for (pos = qb_list_entry((head)->prev, typeof(_pos), member),
  n = qb_list_entry(pos->member.prev, typeof(_pos), member);
  &pos->member != (head);
  pos = n, n = qb_list_entry(n->member.prev, typeof(_n), member))

Sure can. But beware debuggers really don't like these macros. They get really confused.
I am slowly removing the macros I once put in to the full code because of this.

It seems to be both the size of the macro and that there is iteration.

Why not post a patch to the mailing list?
