How to create timer in c++

Question

Two independent timers with two different time periods running simultaneously. Using SetWaitableTimer .

SetWaitableTimer(mhandle, &liDueTime, 0, onCallFunc, this, TRUE);

What iperiod indicate?

Answer 1

After the first timer expiry at lpDueTime , the timer will go off every lPeriod milliseconds unless

• lPeriod is zero. Zero means the timer goes off only once, or
• lPeriod is less than zero. SetWaitableTimer fails if given a negative period.
