Re: [ros-users] Retrieving log level at runtime

Hi Stephane,

This isn't directly an answer to your question, but have you
considered packaging your std::ostringstream work into a function? If
you do

ROS_DEBUG("My aseba message: %s", aseba_to_str(my_aseba));

then aseba_to_str() will only get called when the logging level is set to debug.
