NAME
     net_routeto - indicate which network interface  packets  are
     sent

SYNOPSIS
     #include 

     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 infor-
                mation 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.
