NAME
net_protocol_walk - step through the list of registered network protocols SYNOPSIS
#include <sys/neti.h> net_data_t *net_protocol_walk(net_data_t net); INTERFACE LEVEL
Solaris DDI specific (Solaris DDI). PARAMETERS
net value returned from a successful call to net_protocol_lookup(9F). DESCRIPTION
The net_protocol_walk() function walks through all of the network protocols that have been registered with this interface. The initial call to net_protocol_walk() should be made by passing in NULL as the value for net. When this function returns NULL, the end of the list has been reached. A caller of net_protocol_walk() is required to walk through the entire list of network protocols, until NULL is returned or, when finished with using the value returned, pass it into a call to net_protocol_release(9F). RETURN VALUES
The net_protocol_walk() function returns NULL when the end of the list is returned. Otherwise, it returns a non-NULL value as a token for being passed into other function calls within this interface. CONTEXT
The net_protocol_walk() function may be called from user, kernel, or interrupt context. ATTRIBUTES

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. ATTRIBUTES
