device represented by the layered driver handle
SYNOPSIS
#include <sys/sunldi.h>
int ldi_get_eventcookie(ldi_handle_t lh, char *name ddi_eventcookie_t *
ecp);
INTERFACE LEVEL
Solaris DDI specific (Solaris DDI)

ldi_handle_t lh
Layered handle.
char *name
NULL-terminated string containing the event name.

DESCRIPTION
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).
RETURN VALUES
DDI_SUCCESS Cookie handle is returned.
DDI_FAILURE Request was not serviceable by any nexus driver
in the target device's ancestral device tree
hierarchy.
CONTEXT
This function may be called from user or kernel contexts.
