unicoap_preprocessing_result_t	unicoap_exchange_preprocess (unicoap_packet_t *packet, unicoap_messaging_flags_t *flags, unicoap_exchange_arg_t *arg, bool truncated)
	Performs initial processing of a CoAP packet after it has been parsed.
int	unicoap_exchange_process (unicoap_packet_t *packet, unicoap_exchange_arg_t arg)
	Processes message.
int	unicoap_exchange_release_endpoint_state (const unicoap_endpoint_t *endpoint)
	Releases all buffers and state allocated in connection with the given endpoint.
int	unicoap_messaging_process_rfc7252 (const uint8_t *pdu, size_t size, bool truncated, unicoap_packet_t *packet)
	Internal RFC 7252 messaging inbound processor.
int	unicoap_messaging_send (unicoap_packet_t *packet, unicoap_messaging_flags_t flags)
	Forwards packet to messaging layer and the corresponding driver for further message processing, encoding, and transport I/O.
int	unicoap_messaging_send_rfc7252 (unicoap_packet_t *packet, unicoap_messaging_flags_t flags)
	Sends CoAP over UDP or DTLS packet, see unicoap_messaging_send.
void	unicoap_generate_token (uint8_t *token)
	Generates new token.
static unicoap_messaging_flags_t	_messaging_flags_resource (unicoap_resource_flags_t resource_flags)

Server
int	unicoap_server_process_request (unicoap_packet_t *packet, const unicoap_resource_t *resource)
	Informs the unicoap server a new packet has been preprocessed and can be handled.
int	unicoap_server_send_response_body (unicoap_packet_t *packet, const unicoap_resource_t *resource)
	Sends entire response body, may be split into parts and then sent.
