NAME
       ldi_get_eventcookie - retrieve NDI event service cookie

SYNOPSIS
       #include <sys/ddi_obsolete.h>

       int ldi_get_eventcookie(ldi_handle_t lh, char *name
	    ddi_eventcookie_t *ecp);

INTERFACE LEVEL
       Obsolete

PARAMETERS
       ldi_handle_t lh		 Layered handle.

       char *name		 null-terminated string containing the event name.

       ddi_eventcookie_t *ecp	 Pointer to the kernel event cookie.

DESCRIPTION
       This  function is obsolete and is only maintained for compatibility. Use of this function is strongly discouraged. For equivalent function-
       ality 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).

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.
