ConfigManager API reference =============================== Caliper provides several built-in performance measurement and reporting configurations. These can be activated from within a program with the `ConfigManager` API using a short configuration string. Configuration strings can be hard-coded in the program or provided by the user in some form, e.g. as a command-line parameter or in the programs's configuration file. To access and control the built-in configurations, create a :cpp:class:`cali::ConfigManager` object. Add a configuration string with `add()`, start the requested configuration channels with `start()`, and trigger output with `flush()`: .. code-block:: c++ #include int main(int argc, char* argv[]) { cali::ConfigManager mgr; if (argc > 1) mgr.add(argv[1]); if (mgr.error()) std::cerr << "Config error: " << mgr.error_msg() << std::endl; // ... mgr.start(); // start requested performance measurement channels // ... (program execution) mgr.flush(); // write performance results } API Reference ------------------------------- .. doxygengroup:: ControlChannelAPI :project: caliper :members:
