ctype-python-long int时间太长，无法转换-

本文介绍了ctype-python-long int时间太长，无法转换-的处理方法，对大家解决问题具有一定的参考价值，需要的朋友们下面随着小编来一起学习吧！

问题描述

问题：

代码：

from ctypes import *
from ctypes.wintypes import *

PID = 4016

address = 0x6C532407C

OpenProcess = windll.kernel32.OpenProcess
ReadProcessMemory = windll.kernel32.ReadProcessMemory
CloseHandle = windll.kernel32.CloseHandle


PROCESS_ALL_ACCESS = 0x1F0FFF

datadummy = b'.'*200
buffer = c_char_p(datadummy)
bufferSize = len(buffer.value)
bytesRead = c_ulong(0)

processHandle = OpenProcess(PROCESS_ALL_ACCESS, False, int(PID))

ReadProcessMemory(processHandle, 
    address, 
    buffer, 
    bufferSize, 
    byref(bytesRead))

CloseHandle(processHandle)

我试图更改bytesRead = c_ulong（0）到其他一些ctype，但是没有成功。我在Windows 8.1系统64位上。经过数小时的搜索，我找不到任何解决方案或类似问题。有人知道这里出什么问题吗？

I tried to change the bytesRead = c_ulong(0) to some other ctypes, but no success. Im on a Windows 8.1 System 64bit. I couldnt find any solution or similiar problems after hours of searching. Does someone know whats wrong here?

推荐答案

经过长时间的失败和错误，我终于有了答案。

After a long time of fail and error I finally have an answer.

from ctypes import *
from ctypes.wintypes import *
import ctypes

OpenProcess = windll.kernel32.OpenProcess
ReadProcessMemory = windll.kernel32.ReadProcessMemory
CloseHandle = windll.kernel32.CloseHandle

PROCESS_ALL_ACCESS = 0x1F0FFF

pid = 2320
address = 0x00C98FCC

buffer = c_char_p(b"The data goes here")
val = c_int()
bufferSize = len(buffer.value)
bytesRead = c_ulong(0)

processHandle = OpenProcess(PROCESS_ALL_ACCESS, False, pid)

if ReadProcessMemory(processHandle, address, buffer, bufferSize, byref(bytesRead)):
    memmove(ctypes.byref(val), buffer, ctypes.sizeof(val))

    print("Success: " + str(val.value))
else:
    print("Failed.")

CloseHandle(processHandle)
