.SH "DESCRIPTION"
.PP
Make a copy of both an
sk_buff
and part of its data, located in header\&. Fragmented data remain shared\&. This is used when the caller wishes to modify only header of
sk_buff
and needs private copy of the header to alter\&. Returns
\fBNULL\fR
on failure or the pointer to the buffer on success\&. The returned buffer has a reference count of 1\&.
