void	openlcb::node_id_to_data (NodeID id, void *data)
	Convenience function to render a 48-bit NMRAnet node ID into an existing buffer.

NodeID	openlcb::buffer_to_node_id (const string &buf)
	Converts a 6-byte-long buffer to a node ID.

NodeID	openlcb::data_to_node_id (const void *d)
	Converts 6 bytes of big-endian data to a node ID.

Payload	openlcb::eventid_to_buffer (uint64_t eventid)
	Converts an Event ID to a Payload suitable to be sent as an event report.

uint64_t	openlcb::data_to_eventid (const void *data)
	Takes 8 bytes (big-endian) from *data, and returns the event id they represent.

string	openlcb::error_to_buffer (uint16_t error_code, uint16_t mti)

void	openlcb::error_to_data (uint16_t error_code, void *data)
	Writes an error code into a payload object at a given pointer.

uint16_t	openlcb::data_to_error (const void *data)
	Parses an error code from a payload object at a given pointer.

void	openlcb::append_error_to_buffer (uint16_t error_code, Payload *p)
	Appends an error to the end of an existing buffer.

void	openlcb::buffer_to_error (const Payload &payload, uint16_t error_code, uint16_t mti, string *error_message)
	Parses the payload of an Optional Interaction Rejected or Terminate Due To Error message.

Payload	openlcb::error_payload (uint16_t error_code, Defs::MTI incoming_mti)
	Generates the payload for an OIR or TDE message.

unsigned	openlcb::node_high (NodeID id)

unsigned	openlcb::node_low (NodeID id)

Variables
string	openlcb::EMPTY_PAYLOAD
	A global class / variable for empty or not-yet-initialized payloads.
