#include <sys/ddi_obsolete.h> int ldi_get_eventcookie(ldi_handle_t lh, char *name ddi_eventcookie_t *ecp);
This function is obsolete and is only maintained for compatibility. Use of this function is strongly discouraged. For equivalent functionality provided by new interfaces, see ldi_ev_get_cookie(9F) and ldi_ev_register_callbacks(9F).
The ldi_get_eventcookie() function queries the device tree for a cookie matching the given event name and returns a reference to that cookie. The search is performed by calling up the device tree hierarchy of the device represented by the layered driver handle until the request is satisfied by a bus nexus driver, or the top of the dev_info tree is reached.
The cookie returned by this function can be used to register a callback handler with ldi_add_event_handler(9F).
This function may be called from user or kernel contexts.
