.TH NET_INSTANCE_T 9S "Mar 5, 2012"
.SH NAME
net_instance_t \- packet event structure passed through to hooks
.SH SYNOPSIS
.nf
#include <sys/neti.h>
.fi

.SH INTERFACE LEVEL
illumos DDI specific (illumos DDI).
.SH DESCRIPTION
The \fBnet_instance_t\fR data structure defines a collection of instances to be
called when relevant events happen within \fBIP\fR. The value returned by the
\fBnin_create()\fR function is stored internally and passed back to both the
\fBnin_destroy()\fR and \fBnin_shutdown()\fR functions as the second argument.
The \fBnetid_t\fR passed through to each function can be used to uniquely
identify each instance of \fBIP\fR.
