I need to change both Process Priority and Thread Priority - I've already managed to change Process Priority using SetPriorityClass. So I'm working on changing the Thread Priority. I think my problem up to now has been my vagueness / misunderstandingson terminology - this was not helped by my using Win32::Process::Info to dump all the system process details - it gives Handle and ProcessId with same value, and I assumed Handle meant Thread Handle, and that it was the same as Process Id if the process only had a single thread (i.e. I thought Handle == PID == TID).
But with your detailed explanation of terminology I am now a little closer to Enlightenment. As I see it now, to change a thread priority :-
I need to generate a Duplicate Handle from within the running process.
Use this duplicate handle from within Perl to change the Thread Priority of the original thread.
I'll go away and use the info I now have to make it work. Many thanks for your patience.
