Thread: Whats the proper way of creating an async method ?

Hello everyone, hope you are having a great day.
I want to make one of my blocking methods into a non-blocking one. i.e making it asynchronous if you will.
If I simply do something like

Code:

std::thread t(&MyClass::MyMethod, myobj);
t.detach();

will I be able to interact with this now detached thread? I mean suppose in my method (that I'm running as a second thread) I have a while loop like this :

Code:

while (this->IsRunning())
{
   //lots of stuff 
}

Will I still be able to do

Code:

this->SetRunning(false)

from my main thread and thus end the while loop (therefore ending the child thread execution and thus freeing the memory allocated in that child thread) ?

If detaching the child thread ends all ties with the parent, how should I be doing this then?

To give you a better idea what I'm after, here how it goes:

Basically what I'm trying to do is that I want to create a class that runs a child thread which sits and listens/does something until something of intreset happens/is found, then it fires a callback.
the client would simply create an instance of my class, add some callback handlers and then calls

Code:

myobj.start()

and goes to do whatever else he/she wants to do.
the thread will fire whenever something comes up and clients code gets run. user can also shutdown the processing by doing forexample

Code:

myobj.stop()

which essentially sets that while loop to end.

How should I go about this?
Thank you all in advance
