Subject: Re: [boost] Futures Review - fork_after

I have add the fork_after function to Boost.InterThreads. The prototype allows to execute asynchronously N functions and execute asynchronously a function that depends on the completion of N functions.

    bith::shared_launcher ae;
    BOOST_AUTO(actT, bith::fork_all(ae, fct1, fct2));
    BOOST_AUTO(act,bith::fork_after(ae, fct3, actT));

bith::shared_launcher is an asynchronous executor (AE) that executes asynchronously a function on a new thread.

bith::fork_all request the AE to execute asynchronously each function. It returns a fusion tuple of the asynchronous completion token (ACT) associated the the ae.

bith::fork_after request the AE to execute a function asynchronously once each one of ACTs in the dependency tuple parameter are ready. It is similar to the async_with_dependencies proposed Peter Dimov.

I have used for that Boost.Future (Anthony proposal).

Is there any interest in this kind of feautres?
