I am reading the code of an open source project, and found some code like:

template <typename F>
struct A : std::tr1::_Bind<F>
{
    ...
};

And the code using this struct is like:

A<void(*(PID<T>, void (T::*)(void)))(const PID<T>&, void (T::*)(void))>

I am very confused about these code, basically I do not know what std::tr1::_Bind means? And it seems no much useful info I can get from Internet.

They're using a reserved identifier of a standard library implementation. Chances are this only works on a specific compiler/standard library implementation. – Rapptz Aug 16 '14 at 02:40

It will be related to std::bind (C++11) – OMGtechy Aug 16 '14 at 03:29
