Description

Ultibo Raw Socket Protocol unit

Constants


Raw specific constants RAW_*
Note: Some RAW definitions are in the Protocol or IP modules
 
IP_PROTOCOL_NAME = 'IP';  
RAW_PROTOCOL_NAME = 'RAW';  
 
RAW_TIMEOUT = 0; Wait forever on a RAW Read
RAW_BUFFER_SIZE = 65536; RAW Receive Buffer Size
 
RAW_HEADER_SIZE = 0; No Header for RAW
 
RAW_PACKET_SIZE = 8; SizeOf(TRAWPacket)


Type definitions


Raw packet

PRAWPacket = ^TRAWPacket;

TRAWPacket = record

Note: Some RAW definitions are in the Protocol or IP modules
Note: 8 Bytes (Used by RAWBuffer)
Size:LongWord; LongWord to keep size even
Next:PRAWPacket; Followed by RemoteAddress (4 or 16 Bytes)


Class definitions


Raw specific classes

TRAWProtocolTransport = class(TProtocolTransport)
TRAWProtocol = class(TNetworkProtocol)
TRAWSocket = class(TProtocolSocket)
TRAWBuffer = class(TSocketBuffer)


Public variables

None defined

Function declarations


Initialization functions
