ptp_uhdr
A structure to hold fields that identify a PTP packet
Synopsis:
#include <qnx/ptp/ptp_mod.h>
struct ptp_uhdr {
struct PortIdentity sourcePortId;
uint16_t sequenceId;
uint8_t messageType;
uint8_t domain;
} ;
Data:
- struct PortIdentity sourcePortId
- The PTP port that originated this PTP message.
- uint16_t sequenceId
- The sequence ID.
- uint8_t messageType
- The message type.
- uint8_t domain
- The domain number.
Library:
ptpDescription:
Derived from the ptp_hdr
structure in ptp.h
. These are the fields used to uniquely identify a PTP packet. Requires no padding to allow for quick comparison.
For detailed information about the fields, see the IEEE 1588-2019 documentation.
