Abstract
A system and method for providing user mode applications operating in user mode with access to events that occur at a system device operating in kernel mode, is presented. A user mode application subscribes to events that occur at a system device by issuing a request to an event subscription management module operating in user mode. In response, the event subscription management module issues a first subscription request to a translation module operating in kernel module, via a user mode/kernel module channel. The translation module translates the first subscription message into a second message, and issues the second message to the system device's interface, thereby subscribing to events that occur at the system device. As events occur at the system device, the translation module is notified, and issues corresponding event messages to the event subscription management module.
