NtQuerySystemInformation

Hello,

I am trying to get handles information by using NtQuerySystemInformation
but my code fails for some reason. I am using the following code to call
NtQuerySystemInformation:

from ctypes import *
from ctypes.util import *

class SYSTEM_HANDLE(Structure):

    _fields_ = [("ProcessId", c_ulong),
                ("ObjetTypeNumber", c_byte),
                ("Flags", c_byte),
                ("Handle", c_ushort),
                ("Object", c_void_p ),
                ("GrantedAccess", c_ulong)
                ]

class SYSTEM_HANDLE_INFORMATION(Structure):

    _fields_ = [("HandleCount", c_ulong),
                ("Handles", SYSTEM_HANDLE * 1)
                ]

handleInfoSize = 65536

SystemHandleInformation = 16

c_lib=CDLL(find_library("c"))
malloc=c_lib.malloc
malloc.restype=c_void_p
handleInfo = malloc(handleInfoSize)

pHandleInfo = cast(handleInfo, POINTER(SYSTEM_HANDLE_INFORMATION))

retVal = cdll.ntdll.NtQuerySystemInformation(SystemHandleInformation,
pHandleInfo, handleInfoSize, None)
