.SH NAME
skb_copy \- create private copy of an sk_buff
.SH SYNOPSIS
.sp
\fB
.sp
struct sk_buff * skb_copy  (const struct sk_buff * \fIskb\fB, int \fIgfp_mask\fB);
\fR
.SH "ARGUMENTS"
.TP
\fB\fIskb\fB\fR
buffer to copy
.TP
\fB\fIgfp_mask\fB\fR
allocation priority
.SH "DESCRIPTION"
.PP
Make a copy of both an &sk_buff and its data. This is used when the
caller wishes to modify the data and needs a private copy of the
data to alter. Returns NULL on failure or the pointer to the buffer
on success. The returned buffer has a reference count of 1.
.PP
As by-product this function converts non-linear &sk_buff to linear
one, so that &sk_buff becomes completely private and caller is allowed
to modify all the data of returned buffer. This means that this
function is not recommended for use in circumstances when only
header is going to be modified. Use \fBpskb_copy\fR instead.
