## 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...
typedef uint8_t | Octet
typedef uint8_t | Octet2[2]
typedef uint8_t | Octet3[3]
typedef uint8_t | Octet4[4]
typedef uint8_t | Enumeration2
typedef uint8_t | Enumeration4
typedef uint8_t | Enumeration8
typedef uint16_t | Enumeration16
typedef uint32_t | Enumeration24
typedef uint8_t | UInteger4

## Enumerations
enum | TimeSource { ATOMIC_CLOCK = 0x10, GPS = 0x20, TERRESTRIAL_RADIO = 0x30, PTP = 0x40, NTP = 0x50, HAND_SET = 0x60, OTHER = 0x90, INTERNAL_OSCILLATOR = 0xA0 }
| 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 }
