Registers a callback routine to be invoked when certain events occur in the kernel.

The callback function will be called, for example when the underlying IOUSBInterface is going to be suspended due to some kind of kernel activity. It will also be called when the underlying IOUSBInterface is resumed. Availability: This function is only available with IOUSBInterfaceInterface650 and above.

Parameter self: Pointer to the IOUSBInterfaceInterface.

Parameter notificationMask: Specifies the desired type of notification (e.g. suspend/resume)

Parameter callback: An IOAsyncCallback2 method. Upon completion, the arg0 argument of the AsyncCallback2 will contain the notification type, and arg1 will contain a notificationToken which should be used when calling AcknowledgeNotification

Parameter refCon: Arbitrary pointer which is passed as a parameter to the callback routine.

Parameter pRegistrationToken: A pointer to a UInt64 which will contain a registration token if the function is successful. This registration token can then later be used to call UnregisterNotification.

Returns: Returns kIOReturnSuccess if successful, kIOReturnNoDevice if there is no connection to an IOService.

§UnregisterNotification: Option<unsafe extern "C-unwind" fn(*mut c_void, u64) -> i32>

Unregisters a previously registered callback routine

The callback routine will no longer be invoked when events occur Availability: This function is only available with IOUSBInterfaceInterface650 and above.

Parameter self: Pointer to the IOUSBInterfaceInterface.

Parameter registrationToken: The registration token which was obtained in the call to RegisterForNotification

Returns: Returns kIOReturnSuccess if successful, kIOReturnNoDevice if there is no connection to an IOService.

§AcknowledgeNotification: Option<unsafe extern "C-unwind" fn(*mut c_void, u64) -> i32>

Acknowledges a notification event

Some events in the kernel will wait for an acknowledgement from all interested parties before proceeding. For example, if an IOUSBInterface is about to be suspended, any User Code which has registered to receive that event will be notified and should acknowledge the notification when it is ready for the IOUSBInterface to be suspended. Availability: This function is only available with IOUSBInterfaceInterface650 and above.

Parameter self: Pointer to the IOUSBInterfaceInterface.

Parameter notificationToken: The notification token which was passed in to the callback routine

Returns: Returns kIOReturnSuccess if successful, kIOReturnNoDevice if there is no connection to an IOService.
