ldi_get_eventcookie - Retrieve an NDI event service cookie for the 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) 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
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. SEE ALSO
