Thread Priority Values

[lmstearn]

Rather than one navigating through -2147483648 to 2147483647 for thread priority values, perhaps it would have been be more consistent to offer (quoted from Process):

L (or Low), B (or BelowNormal), N (or Normal), A (or AboveNormal), H (or High), R (or Realtime).

Most likely too late now, as far as backward compatibility is concerned.

What do you mean?

Priority: Changes the priority (as seen in Windows Task Manager) of the first matching process to Param3 and sets ErrorLevel to its Process ID (PID). If the PID-or-Name parameter is blank, the script's own priority will be changed. If there is no matching process or there was a problem changing its priority, ErrorLevel is set to 0.

Param3 should be one of the following letters or words: L (or Low), B (or BelowNormal), N (or Normal), A (or AboveNormal), H (or High), R (or Realtime). Note: Any process not designed to run at Realtime priority might reduce system stability if set to that level.

For example,

Code: Select all

Thread, Priority, B

looks a little better than

Code: Select all

Thread, Priority, -1147483648

That's all.

As far as I understand it, "Thread Priority" makes no sense in the context of normal/below normal/etc

"Thread Priority" is for the author to manage the priority of pseudo-threads within his own app:

Note that the thread priority only affects interuption between threads of your script, it has nothing to do with the system priority as the Process, Priority affects. (As far as I understand)
You can do this, if you find it more convenient/readable.

Code: Select all

; Example
SetThreadPriority("Low")

SetThreadPriority(p){
	; L (or Low), B (or BelowNormal), N (or Normal), A (or AboveNormal), H (or High), R (or Realtime).
	static priority:={L:-2,B:-1,N:0,A:1,H:2,R:3}
	Thread, Priority, priority[SubStr(p,1,1)]
	return
}

Cheers.

Ah, okay thanks. SetThreadPriority deals with small discrete values where:

A thread with a base priority level above 11 interferes with the normal operation of the operating system

Wonder where they got -2147483648 to 2147483647 from then?

Did you even read the link I pasted? I already told you that AHK's Threads are not real OS threads..

Like to know a little more about AHK threads and their priority attributes.

Code: Select all

SetThreadPriority("Low")

SetThreadPriority(p){
	; L (or Low), B (or BelowNormal), N (or Normal), A (or AboveNormal), H (or High), R (or Realtime).
	;Gets out calculator to derive mean values:
	static priority:={L:-1,610,612,735,B:-536,870,911,N:0,A:536,870,911,H:1,610,612,735,R:2147483647}
	Thread, Priority, priority[SubStr(p,1,1)]
	return
}

Have fun!

sigh.

It's not a choice AHK can make since this is Windows internal.
