net_hook_register(9f)
net_hook_register(9F) Kernel Functions net_hook_register(9F)
NAME
net_hook_register - add a hook to be called in event processing
SYNOPSIS
#include <sys/neti.h>
int net_hook_unregister(net_handle_t net, char *hook_name, hook_t hook);
INTERFACE LEVEL
Solaris DDI specific (Solaris DDI).
PARAMETERS
net value returned from a successful call to net_protocol_reg‐
ister().
hook_name hook name to be registered
hook pointer to a hook_t structure
DESCRIPTION
The net_hook_register() function uses hooks that allow callbacks to be
registered with events that belong to a network protocol. A successful
call to net_hook_register() requires that a valid handle for a network
protocol be provided (the net parameter), along with a hook description
that includes a reference to an available event.
While it is possible to use the same hook_t structure with multiple
calls to net_hook_register(), it is not encouraged.
The hook_t structure passed in with this function is described by
hook_t(9S). The following describes how this structure is used.
h_func Must be non-NULL and represent a function that
fits the specified interface.
h_name Gives the hook a name that represents its owner.
No duplication of h_name among the hooks present
for an event is allowed.
h_flags Currently unused and must be set to 0.
h_hint, h_hintvalue Specify a hint to net_hook_register() on how to
insert this hook. If the hint cannot be speci‐
fied, then an error is returned.
h_arg; May take any value that the consumer wishes to
have passed back when the hook is activated.
RETURN VALUES
If the net_hook_register() function succeeds, 0 is returned. Otherwise,
one of the following errors is returned:
ENOMEM The system cannot allocate any more memory to support regis‐
tering this hook.
ENXIO A hook cannot be found among the given family of events.
EEXIST A hook with the given h_name already exists on that event.
ESRCH A before or after dependency cannot be satisfied due to the
hook with
EBUSY The h_hint field specifies a hint that cannot currently be
satisfied because it conflicts with another hook. An example
of this might be specifying HH_FIRST or HH_LAST when another
hook has already been registered with this value.
CONTEXT
The net_hook_register() function may be called from user or kernel con‐
text.
