_WinApi_GetLogicalProcessorInformation

Recommended Posts

Hi guys,

thanks to this request, I wrote my version of GetLogicalProcessorInformation UDF for x86 e x64:

; #FUNCTION# ========================================================================================================================
; Name...........: _WinAPI_GetLogicalProcessorInformation
; Description ...: Retrieves information about logical processors and related hardware.
; Syntax.........: _WinAPI_GetLogicalProcessorInformation()
; Return values .: On success it returns a bidimensional array: on rows there is the list of processor sets, these are the columns:
;                  |[0] - A logical processor affinity mask, which indicates the logical processors that the information applies to.
;                  |[1] - If setted, then the specified logical processors share a single processor core.
;                  |[2] - How many active processors that share functional units are in the relationship
;                         (it is setted only if the previous element is setted too)
;                  |[3] - If setted, it identifies the NUMA node (it can be 0).
;                  |[4] - If setted, the specified logical processors share a physical package.
;                  |[5] - A bidimensional array: on rows there is the cache list, these are the columns:
;                         |[0] - The cache level
;                         |[1] - The cache associativity
;                         |[2] - The cache line size, in bytes
;                         |[3] - The cache size, in bytes
;                         |[4] - The cache type
;                  On failure it returns -1 and sets @error to non zero:
;                  |-1 - internal error
;                  |-2 - missing DLL (Ws2_32.dll)
; Remarks .......: Search GetLogicalProcessorInformation in MSDN Library.

Usage example:

#include <array.au3>
$array = _WinAPI_GetLogicalProcessorInformation()

_ArrayDisplay($array, "Processor set list:")
For $i = 0 To UBound($array) - 1
    _ArrayDisplay($array[$i][5], "Processor set " & $i + 1 & " cache:")
Next

 Nice version. Thank you. dllcall return type should be BOOL instead BOOLEAN.

 

Saludos

      Here another approach to check if a script was already started using atoms and semaphores.
       
      Atom:
      #include <MsgBoxConstants.au3> Global $iSingleton = Singleton() If Not $iSingleton Then Exit MsgBox($MB_TOPMOST, "Singleton Test", "Process is already running!") EndIf MsgBox($MB_TOPMOST, "Singleton Test", "Singleton atom initialized: " & $iSingleton) Singleton_Delete($iSingleton) ; #FUNCTION# ==================================================================================================================== ; Name ..........: Singleton ; Description ...: Checks if the script has been started already. ; Syntax ........: Singleton([$sOccurrenceName = @ScriptFullPath]) ; Parameters ....: $sOccurrenceName - [optional] a string value. Default is @ScriptFullPath. ; Return values .: If the function succeeds, the return value is the newly created atom or 0 else error is set and false is returned. ; Author ........: UEZ ; Modified ......: ; Remarks .......: If Singleton finds the atom it will return 0 and the atom token will be set to extended macro. It can be used to get the atom string using _WinAPI_AtomGlobalGetName. ; Related .......: ; Link ..........: https://docs.microsoft.com/en-us/windows/win32/api/winbase/nf-winbase-globalfindatomw ; https://docs.microsoft.com/en-us/windows/win32/api/winbase/nf-winbase-globaladdatomw ; Example .......: No ; =============================================================================================================================== Func Singleton($sOccurrenceName = @ScriptFullPath) Local $iFind = _WinAPI_AtomGlobalFind($sOccurrenceName) If @error Then Return SetError(1, 0, False) If $iFind Then Return SetExtended($iFind, 0) Local $iAtom = _WinAPI_AtomGlobalAdd($sOccurrenceName) If @error Then Return SetError(2, 0, False) Return $iAtom EndFunc ;==>Singleton ; #FUNCTION# ==================================================================================================================== ; Name ..........: Singleton_Delete ; Description ...: Deletes the atom generated by the first started script. ; Syntax ........: Singleton_Delete($iAtom) ; Parameters ....: $iAtom - an integer value which was generated by Singleton ; Return values .: True if successful else false. ; Author ........: UEZ ; Modified ......: ; Remarks .......: Don't forget to call Singleton_Delete before first started script ends. ; Related .......: ; Link ..........: https://docs.microsoft.com/en-us/windows/win32/api/winbase/nf-winbase-globaldeleteatom ; Example .......: No ; =============================================================================================================================== Func Singleton_Delete($iAtom) _WinAPI_AtomGlobalDelete($iAtom) If @error Then Return SetError(1, 0, False) Return True EndFunc ;==>Singleton_Delete ;internal functions Func _WinAPI_AtomGlobalFind($sAtomString) Local $aReturn = DllCall("kernel32.dll", "short", "GlobalFindAtomW", "wstr", $sAtomString) If @error Then Return SetError(1, 0, -1) Return $aReturn[0] EndFunc ;==>_WinAPI_AtomGlobalFind Func _WinAPI_AtomGlobalAdd($sAtomString) Local $aReturn = DllCall("kernel32.dll", "short", "GlobalAddAtomW", "wstr", $sAtomString) If @error Then Return SetError(1, 0, -1) Return $aReturn[0] EndFunc ;==>_WinAPI_AtomGlobalAdd Func _WinAPI_AtomGlobalDelete($nAtom) Local $aReturn = DllCall("kernel32.dll", "short", "GlobalDeleteAtom", "short", $nAtom) If @error Then Return SetError(1, 0, -1) Return $aReturn[0] = 0 EndFunc ;==>_WinAPI_AtomGlobalDelete Func _WinAPI_AtomGlobalGetName($nAtom, $iBufferSize = 512) Local $tBufferAtom = DllStructCreate("wchar name[" & $iBufferSize & "]") Local $aReturn = DllCall("kernel32.dll", "uint", "GlobalGetAtomNameW", "short", $nAtom, "struct*", $tBufferAtom, "int", $iBufferSize) If @error Or Not $aReturn[0] Then Return SetError(1, 0, -1) Return $tBufferAtom.name EndFunc ;==>_WinAPI_AtomGlobalGetName  
      Semaphore:
      #include <MsgBoxConstants.au3> #include <WinAPIError.au3> Global $iSingleton = Singleton("&]8h/x87</htFV4-K*&.b.w~") If Not $iSingleton Then Exit MsgBox($MB_TOPMOST, "Singleton Test", "Process is already running!") EndIf MsgBox($MB_TOPMOST, "Singleton Test", "Singleton Semaphore initialized: " & $iSingleton) ; #FUNCTION# ==================================================================================================================== ; Name ..........: Singleton ; Description ...: Checks if the script has been started already. ; Syntax ........: Singleton($sOccurrenceName) ; Parameters ....: $sOccurrenceName - a string value which will be used to create the semaphore handle. ; Return values .: True if Singleton started the first time. False if script was already started ; Author ........: UEZ ; Modified ......: ; Remarks .......: The system closes the handle automatically when the process terminates. The semaphore object is destroyed when its last handle has been closed. ; Related .......: ; Link ..........: https://docs.microsoft.com/en-us/windows/win32/api/winbase/nf-winbase-createsemaphorea ; Example .......: No ; =============================================================================================================================== Func Singleton($sOccurrenceName) If StringLen($sOccurrenceName) > 260 Then $sOccurrenceName = StringLeft($sOccurrenceName, 260) Local $aReturn = DllCall("kernel32.dll", "handle", "CreateSemaphoreA", "ptr", Null, "long", 0, "long", 1, "str", $sOccurrenceName) If @error Or Not $aReturn[0] Then Return SetError(1, 0, -1) Return SetExtended($aReturn[0], $aReturn[0] And _WinAPI_GetLastErrorMessage() = "The operation completed successfully.") EndFunc ;==>Singleton  
      Just start the script twice to see if it works.
      The disadvantage of using atoms is that atoms have a memory that means when your app is crashing or you forgot to delete the atom then the atom does still have the $sOccurrenceName saved and thus Singleton will not work if you use the same same value for $sOccurrenceName.
      With semaphore you don't have this issue.
       
      Thanks to jj2007 and SARG.

      Hello guys! I'm a rookie in AutoIt lol.
      I've tried to looking up in MSDN and the UDFs, but it can only get the GUID of a usual partition and with the GUID to control it. Now I have no ways😥.
      Thanks a lot for your help!

      Using some very ingenious scripts that I found on this forum, I've put together a special-purpose folder watcher that watches a specified folder for printer output files and then either send them to a printer or converts them to a PDF and prints or opens the PDF. The page about this utility is here:
      http://www.columbia.edu/~em36/printfileprinter.html
      The one serious problem that it has is that it seems not to detect a new file if there are more than two or three files already in the watched folder. I can't figure out what I'm doing wrong, and will be grateful for any help. Here is the relevant part of the script. I've left out the functions that test whether the file is in use or not, and that send the raw data to the printer or create a PDF, etc. I hope there's enough code here to make sense of it, and will be very grateful for any help. Again, the problem is that the script doesn't detect newly-created files in watched folders with more than a very few files already in it.
      My totally ignorant guess is that the problem is in the line $iID = _WinAPI_WaitForMultipleObjects(2, $paObj, 0, 0) - but I don't know how to change it and of course I'm only guessing whether it's relevant or not. Many thanks

      This simple dllcall gives me error 5, access denied,
      Func _WinAPI_VkKeyScan($__key) _WinAPI_SetLastError(0) $res = DllCall('User32.dll', 'SHORT', 'VkKeyScan', 'CHAR', $__key) _xConsole('res: '&$res) $_LastErr = _WinAPI_GetLastError() If $_LastErr <> 0 Then _xConsole('Err: {' & $_LastErr & '}> ' & _WinAPI_GetLastErrorMessage()) Return $res EndFunc Am i doing something wrong?
      Also tried VkKeyScanA and W
      Edit:
      I want to send `:` via PostMessage() WM_KEYDOWN

      Not going to dump the code down because it's essentially a keylogger.
