Hello everybody

I've been trying to learn the basics on ROS and i've come across this issue:

when I want to get an argument into a callback function in a normal
subscriber i do this:
 ros::Subscriber sub = n.subscribe<std_msgs::String>("control", 1000,

but if I want to make a similar thing into a service-called function i tried
this (I want to pass the argument 500 into function troca):
 ros::ServiceServer service =

And it doesn't work.

Can somebody help?
Thanks in advance
