Getting Started with ROS on Embedded Systems/User Guide/C++/Names

Name manipulation is an important section for ROS, in here you can find useful commands that work well when doing this manipulation

An useful command is the resolve, which lets you create a name with the namespace of the node and a given name, resulting in node_namespace/name

std::string ros::names::resolve(const std::string& name, bool remap = true);

Another useful command, is the append, which simply appends two strings resulting in left/right

std::string ros::names::append(const std::string& left, const std::string& right);
