SKB_PEEK(9) Linux Networking SKB_PEEK(9)
NAME
skb_peek -
SYNOPSIS
struct sk_buff * skb_peek(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.
