Thanks for the idea. I require to deal only with user-AHK-process.
Meanwhile, I have updated my post with SetDebugPrivilege(). Please have a look.

Thanks for all the help. Smile

Code:
hProc := DllCall("OpenProcess", "Uint", 0x043A, "int", 0, "Uint", pid)



Desired Access 0x43a :
PROCESS_QUERY_INFORMATION=0x400 + PROCESS_CREATE_THREAD=0x2 + PROCESS_VM_READ=0x10 + PROCESS_VM_OPERATION=0x8 + PROCESS_VM_WRITE=0x20

Since I want to call GetCommandLine() from a loop, I might want to pass the hProc instead of PID to this function.

Is there a way to ascertain whether the hProc has enough rights ?

I don't know if there is any other API in the standard dlls, but NtQueryObject is the one. It used to be classified as undocumented one, but seems (partially) documented now:
http://msdn.microsoft.com/en-us/library/bb432383.aspx

Code:
VarSetCapacity(bi,56,0)
DllCall("ntdll\NtQueryObject", "Uint", hProc, "Uint", 0, "Uint", &bi, "Uint", 56, "Uint", 0)
MsgBox % NumGet(bi,4)

Thank you Sean. Very Happy

BTW, is following correct:

Code:
 If ! ( NumGet(bi,4) & 0x43a )
    MsgBox, hProcess does not have enough rights
