NAME

       net_event_notify_register, net_event_notify_unregister - add/delete a function to be called for changes to a event

SYNOPSIS

       #include <sys/hook.h>
       #include <sys/neti.h>

       int net_event_notify_register(net_handle_t family, char
	    *event, hook_notify_fn_t *callback, void *arg);

       int net_event_notify_unregister(net_handle_t family, char
	    *event, hook_notify_fn_t *callback);

       typedef int (* hook_notify_fn_t)(hook_notify_cmd_t command,
	    void *arg, const char *name1, const char *name2, const char
	    *name3);

INTERFACE LEVEL

       Solaris DDI specific (Solaris DDI).

PARAMETERS

       family	   value returned from a successful call to net_protocol_lookup().

       callback    function to call when a change occurs.

       event	   name of the event for which notification of change is desired.

       arg	   pointer to pass into the callback() function when a change occurs.

DESCRIPTION

       The  net_event_notify_register()  function  registers a function represented by the pointer callback to be called when there is a change to
       the event represented by family. The types of changes for which notifications are available for is currently limited to	the  addition  and
       removal of hooks.

       The  net_event_notify_unregister()  function  indicates	that there is no longer any desire to receive notification of changes to the event
       through function calls to the specified callback.

       The name of a hook should be considered a private interface unless otherwise specified. The hook names used by IPFilter in  Solaris  are  a
       public, but uncommitted, interface.

       Multiple  callback  functions may be registered through this interface. The same set of parameters is passed to each callback function. The
       memory referenced through the pointers passed to  the  callback should be treated as pointing to read-only memory. Changing  this  data	is
       strictly prohibited.

       The function that is called when the event occurs must not block any other events.

       The arguments passed through to the callback are as follows (the command is either HN_REGISTER or HN_UNREGISTER):

       name1	is the name of the protocol.

       name2	is the name of the event

       name3	is the name of the hook being added/removed

RETURN VALUES

       If these functions succeed, 0 is returned. Otherwise, the following error is returned:

       EEXIST	 the given callback function is already registered.

CONTEXT

       These functions may be called from user or kernel context.

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 *protocol);

INTERFACE LEVEL

       Solaris DDI specific (Solaris DDI).

PARAMETERS

       id	 network instance identifier.

       family	 name of the network protocol to find.

DESCRIPTION

       The  net_protocol_lookup()  function attempts to locate a data structure that defines what capabilities it is exporting through this inter-
       face. The value returned by this call is guaranteed to be valid until it is passed into a call to net_protocol_release(9F), 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() as the protocol name to gain access to either IPv4 or IPv6 respectively.

RETURN VALUES

       The net_protocol_lookup() function returns NULL if it does not find any knowledge about the  network  protocol  referenced.  Otherwise,	it
       returns a value that can be used with other calls in this framework.

CONTEXT

       The net_protocol_lookup() function may be called from user,  kernel, or interrupt context.
