.TH HOOK_NIC_EVENT 9S "May 1, 2008"
.SH NAME
hook_nic_event \- data structure describing events related to network
interfaces
.SH SYNOPSIS
.LP
.nf
#include <sys/neti.h>
#include <sys/hook.h>
#include <sys/hook_event.h>
.fi
.SH INTERFACE LEVEL
.sp
.LP
Solaris DDI specific (Solaris DDI).
.SH DESCRIPTION
.sp
.LP
The \fBhook_nic_event\fR structure contains fields that relate to an event that
has occurred and belongs to a network interface. This structure is passed
through to callbacks for \fBNE_PLUMB\fR, \fBNE_UNPLUMB\fR, \fBNE_UP\fR,
\fBNE_DOWN\fR and \fBNE_ADDRESS_CHANGE\fR events.
.sp
.LP
A callback may not alter any of the fields in this structure.

.in -2
.sp
.LP
The following fields are set for each event:
.sp
.ne 2
.na
\fB\fBhne_family\fR\fR
.ad
.RS 14n
A valid reference for the network protocol that owns this network interface and
can be in calls to other \fBnetinfo\fR(9F) functions.
.RE
.sp
.ne 2
.na
\fB\fBhne_nic\fR\fR
.ad
.RS 14n
The physical interface to which an event belongs.
.RE
.sp
.ne 2
.na
\fB\fBhne_event\fR\fR
.ad
.RS 14n
A value that indicates the respective event. The current list of available
events is:
.sp
.ne 2
.na
\fB\fBNE_PLUMB\fR\fR
.ad
.RS 21n
an interface has just been created.
.RE
.sp
.ne 2
.na
\fB\fBNE_UNPLUMB\fR\fR
.ad
.RS 21n
an interface has just been destroyed and no more events should be received for
it.
.RE
.sp
.ne 2
.na
\fB\fBNE_UP\fR\fR
.ad
.RS 21n
an interface has changed the state to "up" and may now generate packet events.
.RE
.sp
.ne 2
.na
\fB\fBNE_DOWN\fR\fR
.ad
.RS 21n
an interface has changed the state to "down" and will no longer generate packet
events.
.RE
.sp
.ne 2
.na
\fB\fBNE_ADDRESS_CHANGE\fR\fR
.ad
.RS 21n
an address on an interface has changed. \fBhne_lif\fR refers to the logical
interface for which the change is occurring, \fBhne_data\fR is a pointer to a
\fBsockaddr\fR structure that is \fBhne_datalen\fR bytes long and contains the
new network address.
