I would like to lower the priority of my Perl process on Windows. In Re: Changing Windows Process Priority I found a solution to a very similar problem. From http://sourceware.org/pthreads-win32/manual/PortabilityIssues.html I conclude that I need to set the priority to BELOW_NORMAL_PRIORITY_CLASS, so my solution looks like this: 

use Win32::Process;
my $currentProcess;
if (Win32::Process::Open($currentProcess, Win32::Process::GetCurrentPr
+ocessID(), 0)) {
$currentProcess->SetPriorityClass(BELOW_NORMAL_PRIORITY_CLASS);
} else {
  warn "Can not find myself ($^E)\n";
}

This doesn't compile, however, because BELOW_NORMAL_PRIORITY_CLASS is not defined in Win32::Process (and indeed, the perldocs don't mention this constant).

How can I do this properly?
