#### executor_binder::second_argument_type

The type of the function's second argument.

    typedef see_below second_argument_type;

The type of `second_argument_type` is based on the type `T` of the wrapper's target object:

- if `T` is a pointer to a function type accepting two arguments, `second_argument_type` is a synonym for the return type of `T`;
- if `T` is a class type with a member type `first_argument_type`, then `second_argument_type` is a synonym for `T::second_argument_type`;
- otherwise `second_argument_type` is not defined.

###### Requirements

Header: `boost/asio/bind_executor.hpp`

Convenience header: `boost/asio.hpp`
