Description

The macro HPX_REGISTER_PLAIN_ACTION can be used to register an existing template-free function as a plain action. It relies on a separately defined action type named action_type.

The parameter action_type is the name of the action type to register with HPX.

Example: 

namespace app
{
    template <typename T>
    void some_global_function(T d)
    {
        cout << d;
    }

    // define a new template action type named some_global_action
    template <typename T>
    struct some_global_action
      : hpx::actions::make_action<
              void (*)(T), &some_global_function<T>,
              some_global_action<T> >
    {};
}

// The following macro expands to a series of definitions of global objects
// which are needed for proper serialization and initialization support
// enabling the remote invocation of the function `app::some_global_function`.
//
// Please note the extra parenthesis around both macro arguments.
HPX_REGISTER_PLAIN_ACTION_TEMPLATE((template <typename T>), (app::some_global_action<T>));
