How to wait for a thread till it has started running

Question

I currently have something like this

This is a member of my class

 boost::shared_ptr<boost::thread_group> my_group;

Somewhere else in my code I do this

my_group->create_thread( boost::bind( &Myclass::method, this ) );

Now in the above statement is there a way for me to block/wait till this thread has started ? such as

wait for above thread to lauch and start

Do next stuff after that. 

Answer 1

So, as documentation says:

Postcondition: this->size() is increased by one, the new thread is running.

after calling this member function your thread is already running. You can do your next stuff right after that.
