Promises and Futures are used to ferry a single object from one thread to another. A std::promise object is set by the thread which generates the result. A std::future object can be used to retrieve a value, to test to see if a value is available, or to halt execution until the value is available. template future; template future; // specialization : T is a reference type (R&) template <> future; // specialization : T is void Future A future is an object that can retrieve a value from some provider object or function, properly synchronizing this access if in different threads. The answer is yes using std::future, checkout next solution for it. 2.) C++11 Way : Using std::future and std::promise. std::future is a class template and its object stores the future value. Now what the hell is this future value. In this installment we'll take a look at the "futures" mechanism from C++0x. Futures are a high level mechanism for passing a value between threads, and allow a thread to wait for a result to be available without having to manage the locks directly. Futures and asynchronous function calls What are futures?

An asynchronous operation (created via std::async, std::packaged_task, or std::promise) can provide a std::future object to the creator of that asynchronous operation. The creator of the asynchronous operation can then use a variety of methods to query, wait for, or extract a value from the std::future .

Apr 9, 2012 If C++ is to enter the era of modern concurrency, parallelism, and asynchronicity, it must parallelism, and asynchronicity in future C++ Standards.
