cookie.DESCRIPTION
This function is obsolete and is only maintained for compa-
tibility. Use of this function is strongly discouraged. For equivalent functionality provided by new interfaces, seeldi_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 bya bus nexus driver, or the top of the dev_info tree is
reached. The cookie returned by this function can be used to registera 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 dev-
ice tree hierarchy.SunOS 5.11 Last change: 21 Aug 2007 1
