How to search ROS parameters from Arduino?

I created some parameters using dynamic configure package. I want to access them in arduino using rosserial. I can get normal parameters using getParam() function but the parameters I created using dynamic configure package use a different namespace which is of the format /1324859983924..47929/ And the two numbers ( which I guess are time stamps) change everytime I run the node that creates these parameters and hence I cannot use getParam() command in arduino. In python and C++, there is a command called searchParam(), but I cannot find that command in Node_handle.h library for arduino. The arduino library is here : https://github.com/ros-drivers/rosserial/blob/4ee9a0f1179d87cffa1af2e25eae8c5bc3d93f9e/rosserial_client/src/ros_lib/ros/node_handle.h Can anyone please help me either remove the timestamp or whatever those 2 numbers are from the parameter name or ADD the searchParam() function in the arduino library? Thanks In Advance
