3 new Windows 7 API's

[SFSxOI]

Nothing really exciting, just thought i'd post them in case anyone else is messing around with threads and processors in Windows 7, using three of the new Windows 7 API's - SetThreadIdealProcessorEx, GetCurrentProcessorNumberEx, GetActiveProcessorGroupCount:

Code: Select all

Prototype.i PFNCreateToolhelp32Snapshot(dwFlags.i, th32ProcessID.i) ;
Prototype.b PFNProcess32First(hSnapshot.i, *lppe.PROCESSENTRY32) ;
Prototype.b PFNProcess32Next(hSnapshot.i, *lppe.PROCESSENTRY32) ;

; gets PID of an .exe
; usage: GetPidByName("notepad.exe")
Procedure GetPidByName(p_name$) 
    Protected hDLL.i, process_name$ 
    Protected PEntry.PROCESSENTRY32, hTool32.i 
    Protected pCreateToolhelp32Snapshot.PFNCreateToolhelp32Snapshot 
    Protected pProcess32First.PFNProcess32First 
    Protected pProcess32Next.PFNProcess32Next 
    Protected pid.i 
    
    hDLL = OpenLibrary(#PB_Any,"kernel32.dll") 
    
    If hDLL 
        pCreateToolhelp32Snapshot = GetFunction(hDLL,"CreateToolhelp32Snapshot") 
        pProcess32First = GetFunction(hDLL,"Process32First") 
        pProcess32Next = GetFunction(hDLL,"Process32Next") 
    Else 
        ProcedureReturn 0 
    EndIf 
    
    PEntry\dwSize = SizeOf(PROCESSENTRY32) 
    hTool32 = pCreateToolhelp32Snapshot(#TH32CS_SNAPPROCESS, 0) 
    pProcess32First(hTool32, @PEntry) 
    process_name$ = Space(#MAX_PATH) 
    CopyMemory(@PEntry\szExeFile,@process_name$,#MAX_PATH) 
    
    If  UCase(process_name$) = UCase(p_name$) 
        ProcedureReturn PEntry\th32ProcessID 
    EndIf 
    
    While pProcess32Next(hTool32, @PEntry) > 0 
        process_name$ = Space(#MAX_PATH) 
        CopyMemory(@PEntry\szExeFile,@process_name$,#MAX_PATH) 
        
        If  UCase(process_name$) = UCase(p_name$) 
            ProcedureReturn PEntry\th32ProcessID 
        EndIf 
    
    Wend 
    
    CloseLibrary(hDLL) 
    
    ProcedureReturn 0 
EndProcedure

h=CreateToolhelp32Snapshot_(#TH32CS_SNAPTHREAD,0);

Lib_OpenThread = LoadLibrary_("kernel32.dll")

If Lib_OpenThread
  *h_Thread = GetProcAddress_(Lib_OpenThread, "OpenThread")
  FreeLibrary_(Lib_OpenThread)
EndIf

If (h<>#INVALID_HANDLE_VALUE) 
  te\dwSize=SizeOf(te) 
    If (Thread32First_(h,@te))

EndIf

If Thread_Proc_Handle = #Get_Thread_Handle ; = 1

IdealProc.i = CallFunctionFast(*Func_IdealProcessor, Thread_Handle, @PPROCESSOR_NUMBER, #Null)

FreeLibrary_(Lib_IdealProcessor)

ProcedureReturn IdealProc

EndProcedure

I also posted the associated code i'm using to experiment with (Get_Thread_Process_Handle(Proc_file_mame$, Thread_Proc_Handle.i) and GetPidByName(p_name$) )to help you get started in case you don't already have something like this.

Thanks for posting. Anyway, your link leads to a "sorry page not found" site here.

copy and paste the link, for some reason the forum won't pick up the aspx part...or.....here it is again this time posted with the url tags > http://msdn.microsoft.com/en-us/library ... S.85).aspx
