NAME
skb_peek_tail - peek at the tail of an sk_buff_headSYNOPSIS
- struct sk_buff * skb_peek_tail(struct sk_buff_head * list_);
ARGUMENTS
list_
- list to peek at
DESCRIPTION
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 tail element. The reference count is not incremented and the reference is therefore volatile. Use with caution.
