net_routeto(9F) Kernel Functions for Drivers net_routeto(9F) NAME
net_routeto - indicate which network interface packets are sent SYNOPSIS
#include <sys/neti.h> phy_if_t net_routeto(const net_data_t *net, struct sockaddr *address, struct sockaddr *nexthop); INTERFACE LEVEL
Solaris DDI specific (Solaris DDI). PARAMETERS
net value returned from a successful call to net_protocol_lookup(9F). address network address to find a path out of the machine for. nexthop pointer to the sockaddr structure in which to store the address of the next hop. If this information is not required, the value NULL may be passed instead. DESCRIPTION
The net_routeto() function indicates which network interface packets destined for a particular address would be sent out of, according to the systems network routing tables. If next is supplied as a non-NULL pointer, the IP address of the nexthop router to be used is returned in it. RETURN VALUES
The net_routeto() function returns: -1 The network protocol does not support this function. 0 This function cannot find a route for the address given. >0 Indicates which network interface can be used to reach the given address. CONTEXT
The net_routeto() function may be called from user, kernel, or interrupt context. ATTRIBUTES

net_phylookup(9F) Kernel Functions for Drivers net_phylookup(9F) NAME
net_phylookup - determine if a network interface name exists for a network protocol SYNOPSIS
#include <sys/neti.h> phy_if_t net_phylookup(const net_data_t net, const char *name); INTERFACE LEVEL
Solaris DDI specific (Solaris DDI). PARAMETERS
net value returned from a successful call to net_protocol_lookup(9F). name name of the network interface to find. DESCRIPTION
The net_phylookup() function attempts to resolve the interface name passed in with the network protocol. When called successfully, the value returned represents a network interface that exists, at the time of the call, within the scope of the network interface. This value is only guaranteed to be unique for a name within the scope of the network protocol. RETURN VALUES
The net_phylookup() function returns -1 if it is not supported by the network protocol, and 0 if the named network interface does not exist (or is otherwise unknown). Otherwise, it returns a value greater than 0 representing a network interface that currently exists within the scope of this network protocol. CONTEXT
The net_phylookup() function may be called from user, kernel, or interrupt context. ATTRIBUTES
