The Future Of The Celtic Calling Charleston Wv Festival Revealed

Mar 12, 2024an 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. Jul 21, 2020a future represents the result of an asynchronous operation, and can have two states: Std::future is an object used in multithreaded programming to receive data or an exception from a different thread;

Aug 27, 2021checks if the future refers to a shared state. This is the case only for futures that were not default-constructed or moved from (i.e. Feb 22, 2024the get member function waits (by calling wait ()) until the shared state is ready, then retrieves the value stored in the shared state (if any).

Right after calling this function, valid () is false.. Aug 27, 2021if the future is the result of a call to std::async that used lazy evaluation, this function returns immediately without waiting. Oct 23, 2023unlike std::future, which is only moveable (so only one instance can refer to any particular asynchronous result), std::shared_future is copyable and multiple shared future objects.
