- * Module for CPU profiling based on periodic pc-sampling. |
- * |
- * For full(er) information, see doc/cpuprofile.html |
- * |
- * This module is linked into your program with |
- * no slowdown caused by this unless you activate the profiler |
- * using one of the following methods: |
- * |
- * 1. Before starting the program, set the environment variable |
- * "PROFILE" to be the name of the file to which the profile |
- * data should be written. |
- * |
- * 2. Programmatically, start and stop the profiler using the |
- * routines "ProfilerStart(filename)" and "ProfilerStop()". |
- * |
- * |
- * (Note: if using linux 2.4 or earlier, only the main thread may be |
- * profiled.) |
- * |
- * Use pprof to view the resulting profile output. |
- * % pprof <path_to_executable> <profile_file_name> |
- * % pprof --gv <path_to_executable> <profile_file_name> |
- * |
- * These functions are thread-safe. |
