A Nice routine

If you are using your computer for running your chess program and at the same time for browsing TalkChess, you might want to have your chess program running at a lower priority. You can do this manually with the renice command, or you can build the same functionality into your program. The routine is:

Code: Select all

void Nice(void)
{
  const int rc = setpriority(PRIO_PROCESS, 0, 20);
  
  if (rc != 0)
    Die("Nice", "Bad setpriority");
}

Of course you can also instruct the GUI to run the engines at lower priority. E.g. with XBoard using the option -niceEngines N.

Maybe cpulimit is worth bearing in mind too:

Let's open a thread for each posix function.

That is a much better way of doing it. Arena has this feature also.
