I want to implement thread pool using boost::thread class.

I am able to create the threads using below line.

boost::thread Consumer_1(consume);

where consumer_1 is thread and consume is the function bound to it.

Above statement starts the thread as soon as it gets executed.

Now I just want to create the thread and do the binding run time.

I have not yet discovered the boost method to delay this binding.

Can anyone help on this?

The binding can't be done later. For principal reasons—a thread of execution has to be executing something.

What you need to do is create a function, that will take jobs, represented as boost::function, from a queue and execute them. Than run this function in one or more threads.

I am not sure there is a thread-safe queue, but you can always use a regular std::deque with boost::condition_variable for waking up the threads and boost::mutex for locking the deque.

You might want to look at Boost.Asio too. See also here.

    +1 For suggesting Asio. You probably don't want to use your own threadpool in production code. If you have to, check out Williams' 'C++ Concurrency in Action' book which has a whole chapter on the topic, discussing the many many things that you can do wrong. – ComicSansMS Aug 23 '13 at 10:18
