Windows Driver Kit DDI reference (ne-wdm-_io_container_notification_class)

_IO_CONTAINER_NOTIFICATION_CLASS enumeration

Description

The IO_CONTAINER_NOTIFICATION_CLASS enumeration contains constants that indicate the classes of events for which a kernel-mode driver can register to receive notifications.

Constants

`IoSessionStateNotification`

Session state notifications. The driver uses this enumeration constant to request notifications about changes in the state of user sessions that the driver is interested in.

`IoMaxContainerNotificationClass`

Specifies the maximum value in this enumeration type.

Remarks

To register for notifications, a driver calls the IoRegisterContainerNotification routine and sets this routine's NotificationClass parameter to an IO_CONTAINER_NOTIFICATION_CLASS constant (other than IoMaxContainerNotificationClass). Currently, IoRegisterContainerNotification supports only NotificationClass = IoSessionStateNotification.
