Introduction

File contains base datatypes used, as per IEEE 802.1AS Standard Documentation.

Data Structures
struct	PortIdentity
	The portIdentity identifies a port of a time-aware system. More...

struct	ClockQuality
	The clock quality represents quality of clock. More...

struct	UInteger48
	48bit variable, lsb is 32 bits More...

struct	UInteger48m32
	48bit variable, msb is 32 bits More...

struct	UInteger112
	UInteger112 (802.1AS, 10.3.2 systemIdentity) More...

struct	UInteger224
	UInteger224 (802.1AS, 10.3.4 time-synchronization spanning tree priority vectors ) More...

struct	ScaledNs
	The ScaledNs type represents signed values of time and time interval in units of 2e-16 ns. More...

struct	UScaledNs
	The ScaledNs type represents unsigned values of time and time interval in units of 2^-16 ns. More...

struct	TimeInterval

struct	Timestamp
	The Timestamp type represents a positive time with respect to the epoch. More...

struct	ExtendedTimestamp
	The ExtendTimestamp type represents a positive time with respect to the epoch. The fractionalNanoseconds member is the fractional portion of the timestamp in units of 2^16 ns. More...

Macros
#define	MAX_PATH_TRACE_N 179
	Macro to define maximum path trace. More...

#define	CLOCK_IDENTITY_LENGTH 8
	Macro which defines Clock Identity Length. More...

#define	SCALEDNS_FACTOR 0x10000

#define	VALUE_DISABLED 0u

#define	VALUE_ENABLED 1u

Typedefs
typedef uint8_t	ClockIdentity[CLOCK_IDENTITY_LENGTH]

typedef uint8_t	Nibble
	Primitive data types specifications for IEEE 802.1AS. All non-primitive data types are derived from the primitive types, signed integers are represented as two's complement form. More...

	the type of source of time used by a ClockMaster(802.1AS, 8.6.2.7 timeSource) More...

enum	PTPPortState { DisabledPort = 3, MasterPort = 6, PassivePort = 7, SlavePort = 9 }
	value of the port state (802.1AS 14.8.3 portState) More...

enum	gmsync_status_t { GMSYNC_UNSYNC =0, GMSYNC_SYNC, GMSYNC_SYNC_STABLE }

Functions
