Data Structures
struct	AddressData
struct	AddressItem
struct	CipCommonPacketFormatData
	A variant of a CPF packet, including item count, one address item, one data item, and two Sockaddr Info items. More...
struct	DataItem
struct	SocketAddressInfoItem
	CPF Sockaddr Item. More...

Enumerations
enum	CipItemId {   kCipItemIdNullAddress = 0x0000, kCipItemIdListIdentityResponse = 0x000C, kCipItemIdConnectionAddress = 0x00A1, kCipItemIdConnectedDataItem = 0x00B1,   kCipItemIdUnconnectedDataItem = 0x00B2, kCipItemIdListServiceResponse = 0x0100, kCipItemIdSocketAddressInfoOriginatorToTarget = 0x8000, kCipItemIdSocketAddressInfoTargetToOriginator = 0x8001,   kCipItemIdSequencedAddressItem = 0x8002 }
	CPF is Common Packet Format CPF packet := <number of items> {<items>} item := <TypeID> <Length> <data> <number of items> := two bytes <TypeID> := two bytes <Length> := two bytes <data> := <the number of bytes specified by Length> More...

Functions
int	AssembleIOMessage (const CipCommonPacketFormatData *const common_packet_format_data_item, ENIPMessage *const message)
int	AssembleLinearMessage (const CipMessageRouterResponse *const message_router_response, const CipCommonPacketFormatData *const common_packet_format_data_item, ENIPMessage *const outgoing_message)
	Copy data from message_router_response struct and common_packet_format_data_item into ENIPMessage struct outgoing_message via encapsulation. More...
EipStatus	CreateCommonPacketFormatStructure (const EipUint8 *data, size_t data_length, CipCommonPacketFormatData *common_packet_format_data)
	Creates Common Packet Format structure out of data. More...
int	NotifyCommonPacketFormat (EncapsulationData *const received_data, const struct sockaddr *const originator_address, ENIPMessage *const outgoing_message)
int	NotifyConnectedCommonPacketFormat (const EncapsulationData *const received_data, const struct sockaddr *const originator_address, ENIPMessage *const outgoing_message)

Variables
CipCommonPacketFormatData	g_common_packet_format_data_item
	Data storage for the any CPF data Currently we are single threaded and need only one CPF at the time. For future extensions towards multithreading maybe more CPF data items may be necessary. More...
