[ROS2] What is the equivalent API in C++ for ros2 param set? [closed]

edit

This is the closest equivalent:

http://docs.ros2.org/dashing/api/rclc...

In that is can set one or more parameters on any node (remote or local) by name and will return when the setting of the parameter is complete (synchronous).

There is an Asynchronous version as well which returns a future:

http://docs.ros2.org/dashing/api/rclc...

Here's the examples:

Note that in this example it is getting and setting parameters on the local node, but you can also use the same class to get and set parameters on remote nodes given their name.
