NAME <\/a> <\/h2>\n

skb_peek \u2212 peek an sk_buff<\/p>\n

SYNOPSIS <\/a> <\/h2>\n

#include <\/b><\/p>\n\n\n
<\/td>\n\n

struct sk_buff *skb_peek(struct sk_buff_head<\/b> *list_<\/i>);<\/b><\/p>\n<\/td>\n

 <\/td>\n<\/tr>\n<\/table>\n

DESCRIPTION <\/a> <\/h2>\n

The skb_peek<\/b> function extracts the head element of list_<\/i>, without modifying list_<\/i>. It is important to note that this is not necessarily a safe operation, as list_<\/i> maintains the original sk_buff, and other operations on list_<\/i> may effect it. To be safe, either disable interrupts using cli<\/b>(9), call skb_peek<\/b>, copy the data necessary to continue, and re-enable interrupts using sti<\/b>(9), or use skb_dequeue<\/b>(9).<\/p>\n

RETURN VALUE <\/a> <\/h2>\n

Returns a pointer to sk_buff if there is a next element on the list_<\/i>. Otherwise, returns NULL.<\/p>\n

AVAILABILITY <\/a> <\/h2>\n

Linux 1.0+<\/p>\n
