This function may block for longer than timeout_duration due to. Blocks until the result becomes available. Std::future is an object used in multithreaded programming to receive data or an exception from a different thread;
In general, it probably doesn't. Most likely, as you aren't doing this just for fun, you actually need the. The class template std::future provides a mechanism to access the result of asynchronous operations:
Valid() == true after the call. If the future is the result of a call to std::async that used lazy evaluation, this function returns immediately without waiting. The 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. The behavior is undefined if valid () is false before the call to this. If the future is the result of a call to async that used lazy evaluation, this function returns immediately without waiting.
In this case it does work. A future represents the result of an asynchronous operation, and can have two states: An asynchronous operation (created via std::async, std::packaged_task,.
Std::future is an object used in multithreaded programming to receive data or an exception from a different thread; One plausible scenario is existence of another future grants that are assigned on schema level to different role. I'm wondering how this break in backwards compatibility should in general be navigated.
