Thread Synchronization is basically suspending (making one thread wait) until the other thread meets a certain condition.
Now some of you know the regular Join(), which suspends the calling thread until the called thread meets the condition of finish.
But , I would like to take a look at the Auto Reset Event Class,
which allows synchronization between two threads who’s timings do not align.
There are three basic players in this game:
1. public static AutoResetEvent eventReset = new AutoResetEvent(false) – creates the AutoResetEvent queue instance
2. eventReset.WaitOne() – stops the thread and stacks it into the AutoResetEvent queue by order of arrival.
3. eventReset.Set() – Resumes the first waiting thread in the AutoResetEvent queue.
so how do we use them? we can declare a function and then in the main program start a thread and have it wait until a certain condition is met or lock is passed.
public static void proc() {
// Do some work..
eventReset.WaitOne();
}
public static AutoResetEvent eventReset = new AutoResetEvent(false);
public static void Main(string[] args) {
Thread thread = new Thread(proc);
thread.start();
Thread thread2 = new Thread(proc);
thread2.start();
// execution of code... until we call Set() to resume the first suspended thread.
eventReset.Set(); // release first thread...
eventReset.Set(); // release second thread...
}
