SKB_PEEK(9) Linux Networking SKB_PEEK(9) NAME skb_peek - peek at the head of an sk_buff_head SYNOPSIS struct sk_buff * skb_peek(const 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 head element. The reference count is not incremented and the reference is therefore volatile. Use with caution. COPYRIGHT Kernel Hackers Manual 3.11 November 2013 SKB_PEEK(9)[top]
