NAME
       net_lifgetnext - search through a list of logical network interfaces

SYNOPSIS
       #include <sys/neti.h>

       net_if_t net_lifgetnext(const net_data_t net, const phy_if_t ifp,
	    net_if_t lif);

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).

       lif    value returned from a successful call to this function.

DESCRIPTION
       The  net_lifgetnext()  function	is used to search through all of the logical interfaces that are associated with a physical network inter-
       face. To start searching through this list, a value of 0 should be passed through as the value of lif. When 0 is returned by this function,
       the last of the interfaces owned by this protocol has been reached.

       When  called  successfully, the value returned represents a logical interface that exists, at the time of the call, within the scope of the
       network interface and its assigned network protocol. This value is only guaranteed to be unique for a name within the scope of the  network
       interface and its assigned protocol.

EXAMPLES
	    net_data_t net;
	     phy_if_t ifp;
	     net_if_t lif;
	     char buffer[32];
	     net_ifaddr_t atype[1];
	     struct sockaddr_in sin[1];

	     net = net_protocol_lookup("inet");

	     if (net != NULL) {
		  atype[0] = NA_ADDRESS;
		  ifp = net_phylookup(net, "hme0");
		  for (lif = net_lifgetnext(net, 0); lif != 0;
			lif = net_lifgetnext(net, lif)) {
			/* Do something with lif */
			if (net_getlifaddr(net, ifp, lif, 1, atype, sin) == 0)
			      printf("hme0:%d %x0, lif,
				  ntohl(sin[0].sin_addr.s_addr));
		   }
	       }

RETURN VALUES
       The  net_lifgetnext()  function	returns  a value of -1 if it is not supported by the network protocol and a value of 0 if an attempt to go
       beyond the last network interface is made. Otherwise, it returns a value representing a network interface.

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