How to terminate a thread in another thread

Question

See more:

I have created thread by using std::thread in C++.

std::thread thread_variable(function_name);

With above code, it will create a thread.
And I need to terminate this thread by using thread_variable in another thread, like TerminateThread() win32 api.

How can this be done?
Thank you

What I have tried:

I have tried to use desctructor of std::thread, but thread is working well.
Thank you

To communicate a command from one thread to another, you would need to "signal" the thread and then perform an action. In most simple of the ways, that can be done using a variable that notifies ThreadXYZ to finish. A thread will execute just once. In this scenario, most likely the thread is in a while loop that is preventing the thread to finish.

A thread finishes itself; based on a condition, or the statements. To terminate a thread, you can kill it, but that is not a recommended approach it is might lead to memory leaks.

Don't post again and again the same question. There is no way in standard C++ to do what you want. Rick York posted here[^] the usual way to accomplish the task.
An alternative is using the underlying API of your operative system by means of the thread native_handle.

See, for instance c++ - How to stop an std::thread from running, without terminating the program - Stack Overflow[^].

There are different solutions possible, the most obvious is to use a global variable (boolean, mutex or handle) to signal the exit.

pseudo-code:

C++

bool stopThread = false;

void threadOne()
{
  if( timeToLeave ) {
    stopThread = true;
  }
}

void threadTwo()
{
  while( !stopThread ) {
    //do silly stuff, maybe some waiting
  }
}

If you dont like it read the documenation and "maybe" you can do stuff like that

C++

std::thread *myThread = new std::thread(...);//some working constructor
delete myThread;

I wish you good luck...
