Kernel functions			  net_protocol_lookup(9F)



NAME
     net_protocol_lookup - locate an implementation of a  network
     layer protocol

SYNOPSIS
     #include <sys/neti.h>

     net_data_t	net_protocol_lookup(netid_t id,	const char  *pro-
     tocol);

INTERFACE LEVEL
     Solaris DDI specific (Solaris DDI)

PARAMETERS
     id

	 network instance identifier.



     family
	 name of the network protocol to find.



DESCRIPTION
     This function attempts  to	 locate	 a  data  structure  that
     defines  what  capabilities  it  is  exporting  through this
     interface.	 The value returned by this call is guaranteed to
     be	  valid	  until	  it   is   passed   into   a	call   to
     net_protocol_release(), after which it should no  longer  be
     treated as	valid.

     The protocol must be a registered name of a network protocol
     that   has	  been	registered.   The  symbols  NHF_INET  and
     NHF_INET6 should be passed	to net_protocol_lookup(9f) as the
     protocol  name to gain access to either IPv4 or IPv6 respec-
     tively.

RETURN VALUE
     This  function  returns  NULL  if	it  could  not	find  any
     knowledge	about  the network protocol referenced and other-
     wise returns a value that can be used with	 other	calls  in
     this framework.
