Hi Marianne,

There are member functions in the RTObject_impl class, which all
RT-Components inherit from, for adding and removing callbacks on the
configuration parameters. They are called
addConfigurationParamListener() and removeConfigurationParamListener().

The basic idea is that you create an instance of a callback functor,
which inherits from the ConfigurationParamListener class. You then call
addConfigurationParamListener(), passing in the type of listener and a
pointer to an instance of your functor. When a configuration parameter
is updated, your functor will be called.

Unfortunately, we don't have any examples of doing this in an RTC yet,
but if you look in the ComponentObserverConsumer object from the
observer add-on library (in src/ext/sdo/observer/ in the OpenRTM-aist
source), you can see it doing the same thing via the remote interface.
