## Socket Buffer Functions

struct sk_buff — socket buffer
skb_queue_empty — check if a queue is empty
skb_get — reference buffer
skb_cloned — is the buffer a clone
skb_header_cloned — is the header a clone
skb_header_release — release reference to header
skb_shared — is the buffer shared
skb_share_check — check if buffer is shared and if so clone it
skb_unshare — make a copy of a shared buffer
skb_peek —
skb_peek_tail —
skb_queue_len — get queue length
__skb_queue_after — queue a buffer at the list head
skb_put — add data to a buffer
skb_push — add data to the start of a buffer
skb_pull — remove data from the start of a buffer
skb_headroom — bytes at buffer head
skb_tailroom — bytes at buffer end
skb_reserve — adjust headroom
skb_trim — remove end from a buffer
pskb_trim_unique — remove end from a paged unique (not cloned) buffer
