std_thread

A very simple thread pool based on std::thread or boost::thread.

This instantiates a asio::io_service and a latchable asio::io_service::work to keep any threads working until the instance is destructed.

class std_thread_pool
      : public thread_source
{
  // ...
};

Function	Description	Parameters
std_thread_pool(size_t no)	Constructs a thread pool of no workers.	size_t: no: The number of worker threads to create
~std_thread_pool()

asio::io_service & io_service()	Returns the underlying io_service.
template<class R> void enqueue(enqueued_task< R > task)	Sends a task to the thread pool for execution.	enqueued_task< R >: task:
template<class F> shared_future< typename std::result_of< F()>::type > enqueue(F f)	Sends some callable entity to the thread pool for execution.	F: f: Any instance of a callable type	An enqueued task for the enqueued callable
void add_workers(size_t no)	Adds more workers to the thread pool.	size_t: no: The number of worker threads to add
