 NET_GETLIFADDR 9F "Oct 13, 2008"
 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.



0


Successful completion.



1


Unsuccessful.




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