net_getlifaddr(9F)					   Kernel Functions for Drivers 					net_getlifaddr(9F)

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

       Solaris DDI specific (Solaris 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 infor-
		  mation 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  inter-
		       face.

       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  pack-
		       ets.

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.
