bind2nd (STL/CLR)

Generates a binder2nd for an argument and functor.

template<typename Fun,  
    typename Arg>  
    binder2nd<Fun> bind2nd(Fun% functor,  
        Arg right);  

Arg
The type of the argument.

Fun
The type of the functor.

functor
The functor to wrap.

right
The second argument to wrap.

The template function returns binder2nd (STL/CLR)<Fun>(functor, right). You use it as a convenient way to wrap a two-argument functor and its second argument in a one-argument functor that calls it with a first argument.
