The profiling library has been updated in a big way. The new files are at: http://www.cdiggins.com/profiler/v2/profiler.hpp http://www.cdiggins.com/profiler/v2/profile_manager.hpp http://www.cdiggins.com/profiler/v2/high_resolution_timer.hpp and as a special treat for Brian there is: http://www.cdiggins.com/profiler/v2/custom_profile_manager.hpp This last version shows one possible way of using the current library to associate meta-data with profiles. Instead of using a multi-index internally, I push the data into a multi-index to generate a custom report. I am not super happy with this version, it is more complicated than I would like, but it does work. Christopher Diggins Object Oriented Template Library (OOTL) http://www.ootl.org
