#include <sys/ddi_obsolete.h> int ldi_remove_event_handler(ldi_handle_t lh, ldi_callback_id_t id);
Obsolete
ldi_handle_t lh
Layered handle representing the device for which the event notification is requested.
ldi_callback_id_t id
Unique system-wide registration ID returned by ldi_add_event_handler(9F) upon successful registration.
This function is obsolete and is only maintained for compatibility.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_register_callbacks(9F) and ldi_ev_remove_callbacks(9F).
The ldi_remove_event_handler() function removes the callback handler specified by the registration ID (ldi_callback_id_t). Upon successful removal, the callback handler is removed from the system and is not invoked at the event occurance.
DDI_SUCCESS
Callback handler removed successfully.
DDI_FAILURE
Failed to remove callback handler.
This function can be called from user and kernel contexts only.
