Thread pool Implementation using Boost::thread class

Question

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?

Answer 1

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 .
