You can use yaml-cpp to read the dump file yourself, but I don't recommend it. For most ROS applications, <rosparam load ...> will be cleaner and more flexible.
Why do you prefer handling it yourself?

ANSWER: to provide parameter persistence.
UPDATE: I think the usual solution is to run "rosparam dump" before shutting down the parameter server.
There should be an automatic way to do that, but I don't know how. Maybe someone else can suggest a good technique. I guess you could run system("rosparam dump ...") yourself before exiting.
