1. NAME▲

skb_peek - peek at the head of an sk_buff_head

2. SYNOPSIS ▲

struct sk_buff * skb_peek(const struct sk_buff_head *  list_ );

3. ARGUMENTS ▲

list_
    list to peek at

4. 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.
