What new Unicode functions are there in C++0x?
- by luiscubal
It has been mentioned in several sources that C++0x will include better language-level support for Unicode(including types and literals). If the language is going to add these new features, it's only natural to assume that the standard library will as well. However, I am currently unable to find any references to the new standard library. I…Read the article

C++0x - export gone, exception specs deprecated. Will this affect your code?
- by Neil Butterworth
This latest Herb Sutter trip report on the C++0x standardisation process indicates that the committee has decided to completely drop the "export" concept for templates, and to deprecate exception specifications. I think these are both good moves, but I'm interested if anyone out there has a code base where these changes will cause them…Read the article

How does c++ (c++0x) handle implicitly typed variables?
- by LoudNPossiblyRight
I am trying to learn how to use implicitly typed variables in c++. Should i be using 'auto' from C++0x? If so how? Can some one provide me with a simple example or a good tutorial on this? Thank you.Read the article

C++0x and the Lack of Polymorphic Lambdas - Why?
- by Dominar
I've been reviewing the draft version of the upcoming C++0x standard. Specifically the section on lambdas, and am confused as to the reasoning for not introducing polymorphic lambdas. I had hoped we could use code such as the following: template<typename Container> void foo(Container c) { for_each(c.begin(),c.end(),[](T&…Read the article

Can I upgrade Xcode to support a newer version of GCC to learn C++0x?
- by Shane
I would like to jump in learn C++0x, which has matured to a level I'm happy with. Xcode on Snow Leopard 10.6 is currently at GCC 4.2.1, and the new features I'd like to try, like std::shared_ptr, lambdas, auto, null pointer constant, unicode string literals, and other bits and pieces, require at least 4.3 (I believe). Ideally I'd use…Read the article

How do you use C++0x raw strings with GCC 4.5?
- by Rob N
This page says that GCC 4.5 has C++ raw string literals: http://gcc.gnu.org/projects/cxx0x.html But when I try to use the syntax from this page: http://www2.research.att.com/~bs/C++0xFAQ.html#raw-strings #include <iostream> #include <string> using namespace std; int main() { string s = R"[\w\\\w]"; } I get this…Read the article

Why timed lock doesnt throws a timeout exception in C++0x?
- by Vicente Botet Escriba
C++0x allows to lock on a mutex until a given time is reached, and return a boolean stating if the mutex has been locked or not. template <class Clock, class Duration> bool try_lock_until(const chrono::time_point<Clock, Duration>& abs_time); In some contexts, I consider an exceptional situation…Read the article

Are function-local typedefs visible inside C++0x lambdas?
- by GMan - Save the Unicorns
I've run into a strange problem. The following simplified code reproduces the problem in MSVC 2010 Beta 2: template <typename T> struct dummy { static T foo(void) { return T(); } }; int main(void) { typedef dummy<bool> dummy_type; auto x = [](void){ bool b = dummy_type::foo(); }; // auto x = [](void){…Read the article

Why there is no scoped locks for multiple mutexes in C++0x or Boost.Thread?
- by Vicente Botet Escriba
C++0x thread library or Boost.thread define non-member variadic template function that lock all lock avoiding dead lock. template <class L1, class L2, class... L3> void lock(L1&, L2&, L3&...); While this function avoid help to deadlock, the standard do not includes the associated scoped lock to write…Read the article

Will C++0x support __stdcall or extern "C" capture-nothing lambdas?
- by Daniel Trebbien
Yesterday I was thinking about whether it would be possible to use the convenience of C++0x lambda functions to write callbacks for Windows API functions. For example, what if I wanted to use a lambda as an EnumChildProc with EnumChildWindows? Something like: EnumChildWindows(hTrayWnd, CALLBACK [](HWND hWnd, LPARAM…Read the article

C++0x implementation guesstimates?
- by dsimcha
The C++0x standard is on its way to being complete. Until now, I've dabbled in C++, but avoided learning it thoroughly because it seems like it's missing a lot of modern features that I've been spoiled by in other languages. However, I'd be very interested in C++0x, which addresses a lot of my complaints. Any…Read the article

Configuring gcc compiler switches in Qt / QtCreator / QMake

I recently tried to use Qt Creator 1.3.2 / Qt 4.6.2 / gcc 4.4.0 (32-bit version) on Windows 7 (64-bit) to compile an application using some of the experimental C++0x extensions and encountered the following (fatal) error: This file requires compiler and library support for the upcoming ISO C++ standard, C++0x.…Read the article

Is Boost.Tuple compatible with C++0x variadic templates ?

Hi, I was playing around with variadic templates (gcc 4.5) and hit this problem : template <typename... Args> boost::tuple<Args...> my_make_tuple(Args... args) { return boost::tuple<Args...>(args...); } int main (void) { boost::tuple<int, char> t = my_make_tuple(8, 'c'); } GCC…Read the article

What is the motivation behind c++0x lambda expressions?
- by LoudNPossiblyRight
I am trying to find out if there is an actual computational benefit to using lambda expressions in c++, namely "this code compiles/runs faster/slower because we use lambda expressions" OR is it just a neat development perk open for abuse by poor coders trying to look cool? Thanks. PS. I understand this…Read the article

Why is there a sizeof... operator in C++0x?
- by Motti
I saw that @GMan implemented a version of sizeof... for variadic templates which (as far as I can tell) is equivalent to the built in sizeof.... Doesn't this go against the design principle of not adding anything to the core language if it can be implemented as a library function[citation needed]?Read the article

How to enable nullptr from C++0x in the Visual C++ 2010?

How to pass data to a C++0x lambda function that will run in a different thread?

In our company we've written a library function to call a function asynchronously in a separate thread. It works using a combination of inheritance and template magic. The client code looks as follows: DemoThread thread; std::string stringToPassByValue = "The string to pass by value"; AsyncCall(thread,…Read the article

C++0x, How do I expand a tuple into variadic template function arguments?

Consider the case of a templated function with variadic template arguments: template<typename Tret, typename... T> Tret func(const T&... t); Now, I have a tuple t of values. How do I call func() using the tuple values as arguments? I've read about the bind() function object, with call()…Read the article
