This interface allows clients to monitor whether the wayland session is locked or unlocked. Destroy the manager object. All objects created via this interface remain valid. Create a new lock notification object. If the session is already locked when calling this method, the locked event shall be sent immediately. This interface is used by the compositor to send lock notification events to clients. Typically the "locked" and "unlocked" events are emitted when a client locks/unlocks the session via ext-session-lock, but the compositor may choose to send notifications for any other locking mechanisms. The compositor must notfiy after possible transition periods between locked and unlocked states of the session. In the context of ext-session-lock, that means the "locked" event is expected to be sent after the session-lock client has presented a lock screen frame on every output, which corresponds to the "locked" event of ext-session-lock. Destroy the notification object. This event is sent when the wayland session is locked. It's a compositor protocol error to send this event twice without an unlock event in-between. This event is sent when the wayland session is unlocked. It's a compositor protocol error to send this event twice without an locked event in-between. It's a compositor protocol error to send this event prior to any locked event.
