CWaitableTimer

Waitable Time Objects refers to a synchronization object that has the role to be signaled when a specific due time arrives. Take note that when the timer is signaled, the processor must perform the associated instructions. If you set high-frequency periodic timers that keep the processor busy, it means that your computer is unable to maintain a low power state for extensive intervals.

Generally speaking, creating a timer object entails accessing a thread that uses CreateWaitableTimer or CreateWariableTimerEx. Depending on what you want to achieve, you can create a manual-reset timer or a synchronization timer. While in the first case, the timer remains signaled until the timer is called to establish a new timer, the later entails that the state remains unchanged until the thread completes a wait operation on the timer object.

The CWaitableTimer was designed to be an MFC class for Win32 waitable timers Even though waitable timers are not available on Windows 95 or NT 3.x, the code will do the right thing on these operating systems without causing the OS loader to cause your program to fail to load, with the error message "Call to function not defined... ". it goes without saying that the code is Unicode enabled and build configurations are provided.
