# skb\_peek(9)

peek at the head of an sk\_buff\_head

## 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.
