hook_t(9S) Data Structures for Drivers hook_t(9S)NAME
hook_t - callback structure for subscribing to netinfo events
Solaris DDI specific (Solaris DDI).
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().
hook_func_t h_func; /* callback function to invoke */
char *h_name; /* unique name given to the hook */
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,
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
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
