ddi_add_event_handler - add an NDI event service callback handler
SYNOPSIS
#include <sys/dditypes.h>
#include <sys/sunddi.h>
int ddi_add_event_handler(dev_info_t *dip, ddi_eventcookie_t cookie,
void (*handler)(dev_info_t *, ddi_eventcookie_t, void *, void *),
void *arg, ddi_registration_id_t *id);
INTERFACE LEVEL
Solaris DDI specific (Solaris DDI).
PARAMETERS
dev_info_t *dip
Device node registering the callback.
ddi_eventcookie_t cookie
Cookie returned from call to ddi_get_eventcookie(9F).
void (*handler)(dev_info_t *, ddi_eventcookie_t, void *, void *)
Callback handler responsible for handling an NDI event service notification.
void *arg
Pointer to opaque data supplied by the caller. Typically, this would be a pointer to the driver's softstate structure.
ddi_registration_id_t *id
Pointer to registration ID where a unique registration id will be returned. Registration ID must be saved and used when calling
ddi_remove_event_handler(9F) to unregister a callback.
DESCRIPTION
The ddi_add_event_handler() function adds a callback handler to be invoked in the face of the event specifed by cookie. The process of
adding a callback handler is also known as subscribing to an event. Upon successful subscription, the handler will be invoked by the system
when the event occurs. The handler can be unregistered by using ddi_remove_event_handler(9F).
An instance of a driver can register multiple handlers for an event or a single handler for multiple events. Callback order is not defined
and should assumed to be random.
The routine handler will be invoked with the following arguments:
dev_info_t *dip Device node requesting the notification.
ddi_eventcookie_t cookie Structure describing event that occurred.
void *arg Opaque data pointer provided, by the driver, during callback registration.
void *impl_data Pointer to event specific data defined by the framework which invokes the callback function.
RETURN VALUES
DDI_SUCCESS Callback handler registered successfully.
DDI_FAILURE Failed to register callback handler. Possible reasons include lack of resources or a bad cookie.
CONTEXT
The ddi_add_event_handler() and handler() function can be called from user and kernel contexts only.

NOTES
Drivers must remove all registered callback handlers for a device instance by calling ddi_remove_event_handler(9F) before detach completes.
