netinfo(9F) Kernel Functions for Drivers netinfo(9F) NAME
netinfo - interface to network data/functionality DESCRIPTION
The net_getnetid() interface is designed to provide the framework for accessing functionality and data within an implementation of a net- work layer protocol (OSI layer 3.) A protocol may or may not provide full coverage for each of the functions that is described within this interface. Where it does not, it must return an appropriate error condition for that call. Documentation pertaining to the network proto- col, as found in man page section 7pP, must list which functions provided by this interface are and are not supported. ATTRIBUTES

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
