struct sk_buff * skb_peek (struct sk_buff_head * list_);
list_ list to peek at
Peek an &sk_buff. Unlike most other operations you _MUST_ be careful
with this one. A peek leaves the buffer on the list and someone else
may run off with it. You must hold the appropriate locks or have a
private queue to do this.
Returns NULL for an empty list or a pointer to the head element. The
reference count is not incremented and the reference is therefore
volatile. Use with caution.
