lib/cpp/src/thrift/VirtualProfiling.cpp:406–421

* Write the recorded profiling information as pprof files. * * This writes the information using the Google CPU profiler binary data * format, so it can be analyzed with pprof. Note that information about the * protocol/transport data types cannot be stored in this file format. * * See http://code.google.com/p/google-perftools/ for more details. * * @param gen_calls_f The information

 *                        profile_virtual_call() will be written to this file.
