SetConsoleCtrlHandler routine issue

Question

I\'m writting a console application in C++.

I use SetConsoleCtrlHandler to trap close and CTRL+C button. This allows for all my threads to stop and exit properly.

There is no need to wait for any flag from the main thread, the handler terminates as soon as the main thread exits (or after 10s).

BOOL WINAPI ConsoleHandler(DWORD dwType)
{
    switch(dwType) {
    case CTRL_CLOSE_EVENT:
    case CTRL_LOGOFF_EVENT:
    case CTRL_SHUTDOWN_EVENT:

      set_done();//signal the main thread to terminate

      //Returning would make the process exit!
      //We just make the handler sleep until the main thread exits,
      //or until the maximum execution time for this handler is reached.
      Sleep(10000);

      return TRUE;
    default:
      break;
    }
    return FALSE;
}
