Synopsis

// In header: <hpx/lcos/broadcast.hpp>


template<typename Action, typename ArgN, ... > 
  void broadcast_apply_with_index(std::vector< hpx::id_type > const & ids, 
                                  ArgN argN, ...);

Description

The function hpx::lcos::broadcast_apply_with_index performs an asynchronous (fire&forget) distributed broadcast operation resulting in action invocations on a given set of global identifiers. The action can be either a plain action (in which case the global identifiers have to refer to localities) or a component action (in which case the global identifiers have to refer to instances of a component type which exposes the action.

The given action is invoked asynchronously on all given identifiers, and the arguments ArgN are passed along to those invocations.

The function passes the index of the global identifier in the given list of identifiers as the last argument to the action.

Parameters:

`argN`	[in] Any number of arbitrary arguments (passed by by const reference) which will be forwarded to the action invocation.
`ids`	[in] A list of global identifiers identifying the target objects for which the given action will be invoked.
