Process Private Memory Usage Topic is solved

[jNizM]

For 32-bit it should beif (NumGet(addr + 68, "ptr") = PID)
Will add 32-bit later too.. because I just work with 64-bit

[jNizM]

For 32- & 64-Bit

Code: Select all

MsgBox % GetWorkingSetPrivateSize(2580) " K"

GetWorkingSetPrivateSize(PID)
{
	if (DllCall("ntdll.dll\NtQuerySystemInformation", "int", 0x5, "ptr", 0, "uint", 0, "uint*", size) != 0) {
		size := VarSetCapacity(buf, size, 0)
		if (DllCall("ntdll\NtQuerySystemInformation", "int", 0x5, "ptr", &buf, "uint", size, "uint*", 0) != 0)
			return (ErrorLevel := 2) & 0
		addr := &buf
		while (addr) {
			if (NumGet(addr + 56 + A_PtrSize * 3, "ptr") = PID)
				return NumGet(addr + 8, "int64") // 1024
			if !(NumGet(addr + 0, "uint"))
				break
			addr += NumGet(addr + 0, "uint")
		}
	}
	return (ErrorLevel := 1) & 0
}

Fine!

Totally Awesome.

Is there any way to empty the Private Memory?

Is there any way to empty the Private Memory?

You might want to look at this thread:

https://autohotkey.com/board/topic/30042-run-ahk-scripts-with-less-half-or-even-less-memory-usage/
(Run AHK scripts with less (half or even less) memory usage)

Code: Select all

EmptyMem(PIDtoEmpty)
{   
    h:=DllCall("OpenProcess", "UInt", 0x001F0FFF, "Int", 0, "Int", PIDtoEmpty)
    DllCall("SetProcessWorkingSetSize", "UInt", h, "Int", -1, "Int", -1)
    DllCall("CloseHandle", "Int", h)
}

Working Set is ok but Private Bytes is not shrunk. Maybe because it's impossible anyway.

It did not work for Private Bytes. It has an effect on total memory but has no effect on Private Bytes. I have to radically change my application approach and find a different solution.
I was collecting hundreds of thousands of file paths in a single object. And when I needed I could compare quickly. But it has a heavy impact on memory. I will reduce the file paths to 8 bytes with the CRC32 function you made to save memory. I hope this is a logical way. If I thought the CRC16 would be sufficient for this job, my choice would be different.
