bind1st (STL/CLR)

Generates a binder1st for an argument and functor.

template<typename Fun,  
    typename Arg>  
    binder1st<Fun> bind1st(Fun% functor,  
        Arg left);  

Arg
The type of the argument.

Fun
The type of the functor.

functor
The functor to wrap.

left
The first argument to wrap.

The template function returns binder1st (STL/CLR)<Fun>(functor, left). You use it as a convenient way to wrap a two-argument functor and its first argument in a one-argument functor that calls it with a second argument.
