hook_t

- callback structure for subscribing to netinfo events

Synopsis

#include <sys/hook.h>

Interface Level

Solaris DDI specific (Solaris DDI).

Description

The hook_t data structure defines a callback that is to be inserted into a networking event. This data structure must be allocated with a call to hook_alloc() and released with a call to hook_free().

Structure Members

hook_func_t  h_func;      /* callback function to invoke */
char         *h_name;     /* unique name given to the hook */
int          h_flags;
hook_hint_t  h_hint;      /* insertion hint type */
uintptr_t    h_hintvalue; /* used with h_hint */
void         *h_arg;      /* value to pass into h_func */

typedef int (*hook_func_t)(net_event_t token, hook_data_t info, 
              void *); 

HINT TYPES

Hook hints are hints that are used at the time of insertion and are not rules that enforce where a hook lives for its entire lifetime on an event. The valid values for the h_hint field are:

HH_NONE

Insert the hook wherever convenient.

HH_FIRST

Place the hook first on the list of hooks.

HH_LAST

Place the hook last on the list of hooks.

HH_BEFORE

Place the hook before another hook on the list of hooks. The value in h_hintvalue must be a pointer to the name of another hook.

HH_AFTER

Place the hook after another hook on the list of hooks. The value in h_hintvalue must be a pointer to the name of another hook.
