C에서 Boost를 사용하여 스레드 풀을 생성하고 활용하는 방법은 무엇입니까?

// Create IO service and thread group (i.e., thread pool)
boost::asio::io_service ioService;
boost::thread_group threadPool;

// Start I/O service processing loop
boost::asio::io_service::work work(ioService);

// Add threads to the thread pool
threadPool.create_thread(
    boost::bind(&boost::asio::io_service::run, &ioService)
);
threadPool.create_thread(
    boost::bind(&boost::asio::io_service::run, &ioService)
);

// Assign tasks to thread pool
ioService.post(boost::bind(myTask, "Hello World!"));
ioService.post(boost::bind(clearCache, "./cache"));
ioService.post(boost::bind(getSocialUpdates, "twitter,gmail,facebook,tumblr,reddit"));

// Stop I/O service and join threads
ioService.stop();
threadPool.join_all();
