How can I make a thread run on demand in boost, and not automatically?

Question

C++ / C#

Good time!
I am writing a simple server on boost.
In the listener's constructor, I create a boost::thread object and bind it to my handler function.
Why does a new thread start its execution as soon as the boost::thread object is created? Is it possible to make the thread start its execution on demand, and not right away?

thrd_sp = boost::shared_ptr<boost::thread>(
      new boost::thread( boost::bind( &listener::dispatch, this )));

Actually, what you are doing is what is called an active object (for example, in the Oberon language this is a common thing).
You have the wrong architecture: if you want this behavior (as you write), then:
- you must create a thread not in the constructor and not by inheritance ...
- but with a pointer field to the thread that you will activate with a separate run () method, where and the thread will actually be created and run.
