Example #1

void backtrace_log(const char *format, ...) {
  const int log_fd = get_logging_fd();
  if (log_fd >= 0) {
    if (format && format[0]) {
      va_list args;
      va_start(args, format);
      log(format, args);
      va_end(args);
    }

    Frames frames;
    if (get_backtrace(frames, 2))
      ::backtrace_symbols_fd(frames.data(), frames.size(), log_fd);
  }
}

Example #2
