# skb\_clone(9)

duplicate an sk\_buff

## NAME

skb\_clone - duplicate an sk\_buff

**struct sk\_buff \* skb\_clone(struct sk\_buff \*** *skb***, gfp\_t** *gfp\_mask***);**

## ARGUMENTS

## DESCRIPTION

Duplicate an sk\_buff. The new one is not owned by a socket. Both copies share the same packet data but not structure. The new buffer has a reference count of 1. If the allocation fails the function returns **NULL** otherwise the new buffer is returned.
