Special features in new C++0x

[Vijitha Kumara]

Hi Anthony,

Any special features in the new facilities you'd like to highlight or any simplifications provided for concurrency in C++ ?

There are lots of great language features that have been added to C++0x. The two that I think will have the most direct impact on code I write will be the new use of auto for type deduction of variables, the introduction of lambda functions.

These facilities work really well with the new C++0x thread library --- you can pass a lambda to the std::thread constructor, or to std::async to start a thread, and you can use auto to capture the future from std::async without having to type out the type of the returned future:

auto f=std::async([]{return find_the_answer_to_life_the_universe_and_everything();});

As far as concurrency facilities go, std::async is my favourite, but I wouldn't like to give up the RAII lock classes std::lock_guard<> and std::unique_lock<> when dealing with mutexes --- it's just so much easier using them than explicitly locking and unlocking mutexes.

Thanks for the information...
