54 * Note: OCStop() performs operations similar to OCStopPresence(), as well as OCDeleteResource() on
55 * all resources this server is hosting. OCDeleteResource() performs operations similar to

75 * @param handle @ref OCDoHandle to refer to the request sent out on behalf of
76 * calling this API. This handle can be used to cancel this operation
77 * via the OCCancel API.
