31 * Connectivity Abstraction Interface Description APIs.
41 * @brief Callback function type for request delivery.
42 * requestInfo contains different parameters for resource model to understand about the request.
43 * @param object [OUT] Endpoint object from which the request is received. It contains endpoint
44 * address based on the connectivity type.
45 * @param requestInfo [OUT] Identifier which needs to be sent with request.
47 typedef void (*CARequestCallback)(CARemoteEndpoint_t* object, CARequestInfo_t* requestInfo);
50 * @brief Callback function type for response delivery.
51 * responseInfor contains different parameters for resource model to understand about the request.
52 * @param object [OUT] Endpoint object from which the response is received.
