Dear reader, I've been wanting to implement a future in C++ for some time, and combined some code to come up with the attached. The idea is that the future is a function wrapper around a function call which will call the function in a second thread upon creation. Then at a later moment, the future can yield the return value of the wrapped function (or block until this result is know). I'm happy with the result I got so far. It's a very rough draft, and I would like your help to clean up some details: - I would like to have the Future wrapper work with the boost::function< int (argument, argument)> syntax, but I can't figure out how to get the return type from that syntax to allow for the return value to be defined (the d_result member). - What would be the best way to handle function arguments? Binding all the parameters before passing the resulting bound function object seems like the solution, but is it really the best solution? And last but not least: has this already been done and what is the general opinion within the boost community on having a class like this? Greetings, Bram Neijt Attached are two files, one is the Future class and the second is a test program showing it's general functioning. The output of running the test program should show: Creating future Future thread working Main waiting for 3 seconds Future thread working Future thread working Calling upon future to return Future thread working Future thread working Future thread working Future thread working Future thread working Future thread working Future returned: 9
