Detailed Description

Time in milliseconds from arbitrary/unknown start time. Unsigned 32 bits will roll every 49.7 days. _WIN32 = start time = when system was last rebooted.

Member Function Documentation

get_AgeSec()

TIMESECD_t Gray::cTimeSys::get_AgeSec ( ) const

inlinenoexcept

How old is this? (in seconds) current time - this time.

get_AgeSecF()

TIMESECF_t Gray::cTimeSys::get_AgeSecF ( ) const

inlinenoexcept

in float seconds.

get_AgeSys()

TIMESYSD_t Gray::cTimeSys::get_AgeSys ( ) const

inlinenoexcept

How long ago was this ? (was TIMESYS_GetAge(x))

Returns

signed TIMESYS_t (mSec) <0 = t is in the future. >0 = t is in the past.

get_TimeSys()

TIMESYS_t Gray::cTimeSys::get_TimeSys ( ) const

inlinenoexcept

get_TimeTilSecF()

TIMESECF_t Gray::cTimeSys::get_TimeTilSecF ( ) const

inlinenoexcept

in float seconds.

get_TimeTilSys()

TIMESYSD_t Gray::cTimeSys::get_TimeTilSys ( ) const

inlinenoexcept

How long until this time (msec)

Returns

>0 = m_TimeSys is in the future.

GetTimeNow()

static TIMESYS_t Gray::cTimeSys::GetTimeNow ( )

inlinestaticnoexcept

Note

ASSUME this is FAST ! _WIN32 is limited to the resolution of the system timer, which is typically in the range of 10 milliseconds to 16 milliseconds.

InitTime()

void Gray::cTimeSys::InitTime ( TIMESYS_t  t = k_CLEAR )

inlinenoexcept

InitTimeNow()

void Gray::cTimeSys::InitTimeNow ( )

inlinenoexcept

InitTimeNowPlusSec()

void Gray::cTimeSys::InitTimeNowPlusSec ( float  fOffsetSec )

inlinenoexcept

InitTimeNowPlusSys()

void Gray::cTimeSys::InitTimeNowPlusSys ( TIMESYSD_t  iOffset )

inlinenoexcept

isTimeFuture()

bool Gray::cTimeSys::isTimeFuture ( ) const

inlinenoexcept

isTimeValid()

bool Gray::cTimeSys::isTimeValid ( ) const

inlinenoexcept

WaitSpin()

unsigned long GRAYCALL Gray::cTimeSys::WaitSpin ( TIMESYSD_t  t )

static

Wait a certain amount of time. Spin instead of sleeping. Do NOT yield time to other threads. (NOT Sleep)
