2022-01-13 09:51:10 -0500 marked best answer ROS2/create_subscription: How to pass callback arguments

In ROS 1, I was able to pass arguments to the callback function of a subscriber: rospy.Subscriber(topic_name, type, call_back, call_back_arg)

How can I do this in ROS2? My goal is to pass the name of the topic. Because I have a single call back for many topics and when the callback is invoked, I need to know what topic called it. It there a better way to find this? Thank you
