NAME¶
skb_peek - peek at the head of an sk_buff_headSYNOPSIS¶
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.
