Clear memory after loops

[chipmonkboy]

Hello. I just found this "clear memory" function on the website. I do not understand why the code is written that way. So,can anyone explain the code for me please. Also, if I want to run the code, I only need to type _ReduceMemory() in the autoit code right?

Thank you

Func _ReduceMemory($i_PID = -1)
    If $i_PID <> -1 Then
        Local $ai_Handle = DllCall("kernel32.dll", 'int', 'OpenProcess', 'int', 0x1f0fff, 'int', False, 'int', $i_PID)
        $ai_Return = DllCall("psapi.dll", 'int', 'EmptyWorkingSet', 'long', $ai_Handle[0])
        DllCall('kernel32.dll', 'int', 'CloseHandle', 'int', $ai_Handle[0])
    Else
        $ai_Return = DllCall("psapi.dll", 'int', 'EmptyWorkingSet', 'long', -1)
    EndIf

    Return $ai_Return[0]
EndFunc   ;==>_ReduceMemory

there is nothing to explain, the code is a code, it have DllCalls to API funtions that do the all the work, and yes, the only parameter on the function is the PID of the process you want to reduce the memory..

One question, why you need to use this function? what kind of loop are you using?

Look at msdn.

I wrote a script that will run 2 times everyday to backup some files. The script will run 24/7. It's a while loop. I am afraid that the memory will get larger after each loop so I use this script.

It's unlikely that more and more memory will get used. I have a script which loops continually. It performs various jobs in response to hotkeys during the day and every night it makes backups of various files. I rarely turn my computer off and it runs continually for months at a time with no hint of any memory problems.

The memory problem might be for some bad looping code.

Thanks a lot for the fast responses.

Seems this function only works for 32bit(86x) executables, not 64bit. I'm not sure why

Firstly don't necro old threads, secondly search the forum for WinAPIEx and the function _WinAPI_EmptyWorkingSet. Case closed.
