Private Attributes | |
| LARGE_INTEGER | m_freq |
| Stores information about CPU high precision clock. | |
| long | m_timeCurrent |
| Current time of clock. | |
| long | m_timeStart |
| CPU time when clock was started. | |
| long | m_timeoutPeriod |
| Timeout period. | |
| long | m_timeoutStart |
| CPU time when timer was started. | |
| bool | m_highres |
| If true, then high precision CPU clock is available. | |

| cPrecisionClock::cPrecisionClock | ( | ) |
Constructor of cPrecisionClock.
Constructor of cPrecisionClock. Clock is initialized to zero.
| cPrecisionClock::~cPrecisionClock | ( | ) |
Destructor of cPrecisionClock.
Destructor of cPrecisionClock.
| void cPrecisionClock::initialize | ( | ) |
reset clock to zero.
Initialize the clock. Current time is set to zero.
| long cPrecisionClock::start | ( | ) |
start counting from current time of clock.
Start the clock from its current time value. To read the latest time from the clock, use getCurrentTime().
| long cPrecisionClock::stop | ( | ) |
stop clock counting.
Stop the timer. To resume counting call start().
| long cPrecisionClock::getCurrentTime | ( | ) |
read current time of clock. Units are microseconds.
Set the current time of timer. Result is returned in microseconds.
| void cPrecisionClock::setTimeoutPeriod | ( | long | a_timeoutPeriod | ) |
set the period in microseconds before timeout occurs.
Set the period in microseconds before timeout occurs. Do not forget to set the timer on by calling start()
| a_timeoutPeriod | Timeout period in microseconds. |
| bool cPrecisionClock::timeoutOccurred | ( | ) |
return true if timeout has occurred.
Check if timer has expired its timeout period. if so return true.
| double cPrecisionClock::getCPUtime | ( | ) |
