NAME

net_getlifaddr - determine a network address for a given interface

SYNOPSIS

#include <sys/neti.h>
int net_getlifaddr(const net_data_t net, const phy_if_t ifp,


     const net_if_t lif, int const type,


     struct sockaddr* storage);

INTERFACE LEVEL

illumos DDI specific (illumos DDI).

PARAMETERS

net

value returned from a successful call to net_protocol_lookup(9F).

ifp

value returned from a successful call to net_phylookup(9F) or net_phygetnext(9F), indicating which network interface the information should be returned from.

lif

indicates the logical interface from which to fetch the address.

type

indicates what type of address should be returned. See below for more details on this field.

storage

pointer to an area of memory to store the address data.

DESCRIPTION

The net_getlifaddr() function retrieves the address information for each logical interface. Each call to net_getlifaddr() requires that the caller pass a pointer to an array of address information types to retrieve, and an accompanying pointer to an array of pointers to struct sockaddr structures to which to copy the address information. See net_lifgetnext(9F) for an example on how to use this function.

Each member of the address type array should be one of the values listed here.

NA_ADDRESS

Return the network address associated with the logical interface (lif) that belongs to the network interface (ifp).

NA_PEER

Return the address assigned to the remote host for point to point network interfaces for the given network/logical interface.

NA_BROADCAST

Return the broadcast address assigned to the given network/logical interface for network interfaces that support broadcast packets.

NA_NETMASK

Return the netmask associated with the given network/logical interface for network interfaces that support broadcast packets.

RETURN VALUES

The net_getlifaddr() function returns:

-1

The network protocol does not support this function.

Successful completion.

Unsuccessful.

CONTEXT

The net_getifaddr() function may be called from user, kernel, or interrupt context.
