Struct isotp_pdu¶

One decoded ISO-TP frame (protocol data unit). More...

#include <isotp_protocol.h>

Public Attributes¶

Type	Name
uint8_t	block_size BS (FC).
uint8_t	data_length Payload bytes in this frame (SF, FF, CF).
uint8_t	data_offset Index of the first payload byte in the frame.
uint8_t	flow_status FS (FC), not range-checked: see isotp_decode .
uint32_t	message_length SF_DL (SF) or FF_DL (FF): length of the whole message.
uint8_t	sequence_number SN (CF).
uint8_t	st_min Raw STmin byte (FC); convert with isotp_st_min_decode .
uint8_t	type ISOTP_PCI_ frame type.*

Detailed Description¶

Only the members of the decoded frame type are meaningful; the others are zero. The payload is not copied: it is frame[data_offset] .. frame[data_offset + data_length - 1] of the frame passed to isotp_decode.
