Is it possible to kill a spinning thread?

Question

I am using ZThreads to illustrate the question but my question applies to PThreads, Boost Threads and other such threading libraries in C++.

class MyClass: p         


        

Answer 1

Yes,

Define keepAlive variable as an int . Initially set the value of keepAlive=1 .

class MyClass: public Runnable
{
 public:
  void run()
   {
      while(keepAlive)
      {

      }
   }
}

Now, when every you want to kill thread just set the value of keepAlive=0 .

Q. How this works ?

A. Thread will be live until the execution of the function continuous . So it's pretty simple to Terminate a function . set the value of variable to 0 & it breaks which results in killing of thread . [This is the safest way I found till date] .
