#include <sys/hook.h>
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 */ 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 *);
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.
