Thank you, It actually allows me to use references in these functions.

I just tried and g++ is waiting for only references but I need to use pointers and/or values too.

There is a way to use mixed types in template variadic functions ?

For perfect forwarding use:

template<class... T> void call(T&&... t) { foo(std::forward<T>(t)...); }

I tried this one too and it works fine thank you.

However, I use these functions with boost::bind library and actually references are lost when I use it (and I need to). After some google searches, it seems that boost::bind officially does not support this use (due to internal references). So I tried with std::bind because I read somewhere the problem was fixed with its C++11 version. The problem is the same : with std::bind too, references are lost using std::forward.

Does anyone made this duo bind/template variadic functions working together ? And if someone did, how did you do ?

Sorry, I lost context with what you're trying to do, but maybe you want to use boost::ref / std::ref in conjunction with boost::bind / std::bind, respectively? I think that should indicate to the binding framework to hold the bound values by reference rather than by value (if that's what you want). - Jeff
