Await the result of several futures to chain another task
Hi, If I have two futures f1 and f2, can I compose them to a future that completes with the result of f1 and f2 when both f1 and f2 have finished? I'd like to have a future so that I can use the then()http://www.boost.org/doc/libs/1_55_0/doc/html/thread/synchronization.html#th...method to run another transformation. I see method wait_for_all()http://www.boost.org/doc/libs/1_55_0/doc/html/thread/synchronization.html#th...but this method blocks. Best, Kaspar

Hi, I'm working on when_all/when_any functions, but there are a lot of restrictions. See [1]. I don't think it would be completely ready for Boost.1.56. You can play with it, but I don't believe you could use it on a product. Best, Vicente [1] http://svn.boost.org/svn/boost/branches/release/libs/thread/example/future_w....
Thanks, Vicente, for the update and for your efforts – whenever it comes to Boost, this will be great! Cheers, Kaspar On Thu, Dec 5, 2013 at 1:38 PM, Vicente J. Botet Escriba < vicente.botet@wanadoo.fr> wrote:
