The + * kernel and user-level daemon communicate using a connector channel. + * + * The user mode component first registers with the + * the kernel component. Subsequently, the kernel component requests, data + * for the specified keys. In response to this message the user mode component + * fills in the value corresponding to the specified key. We overload the + * sequence field in the cn_msg header to define our KVP message types. + * + * + * The kernel component simply acts as a conduit for communication between the + * Windows host and the user-level daemon. The kernel component passes up the + * index received from the Host to the user-level daemon.
