Q. What is the use of WaitForSingleObject?
The WaitForSingleObject function checks the current state of the specified object. If the object’s state is nonsignaled, the calling thread enters the wait state until the object is signaled or the time-out interval elapses. The function modifies the state of some types of synchronization objects.
Q. How do I stop WaitForSingleObject?
4 Answers. Use WaitForMultipleObject instead, and pass 2 handles. The existing one, and one for an event called something like ‘exit’. During app shutdown, SetEvent on the exit event, and the WaitForMultipleObject will return and you can get it to exit the thread gracefully.

Q. How do I create a DOM event?
The below steps are followed in order to create one using a new Event.
- We create an event using the Event constructor.
- We listen to this event using the addEventListener() method.

- A custom Event named start has now been created.
Q. What is AutoResetEvent and ManualResetEvent?
The short answer is yes. The most important difference is that an AutoResetEvent will only allow one single waiting thread to continue. A ManualResetEvent on the other hand will keep allowing threads, several at the same time even, to continue until you tell it to stop (Reset it).
