Kernel Functions for Drivers net_lifgetnext(9F)
NAME
net_lifgetnext - search through a list of logical network
interfacesSYNOPSIS
#include
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 tonet_protocol_lookup(9F).
ifp value returned from a successful call tonet_phylookup(9F) or net_phygetnext(9F).
lif value returned from a successful call to this func-
tion.DESCRIPTION
The net_lifgetnext() function is used to search through all
of the logical interfaces that are associated with a physi-
cal network interface. 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 inter-
faces 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 inter-
face.CONTEXT
The net_lifgetnext() function may be called from user, ker-
nel, or interrupt context.ATTRIBUTES
