ctype-python-long int太长，无法转换-

问题:

回溯（最近一次调用）：文件“C:\Users\Nutzer\Google 驱动器\Code\Code\memory\u read.py”，第26行，在 byref（ByteRead））ctypes.ArgumentError:参数2:：long int太长，无法转换

代码：

我试图将bytesRead=c_ulong（0）更改为其他一些ctypes，但没有成功。在64位Windows 8.1系统上进行即时通讯。经过几个小时的搜索，我找不到任何解决方案或类似的问题。有人知道这里出了什么问题吗？

经过长时间的失败和错误，我终于有了答案

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)

设置

SIZE\u T=c\u SIZE\u T

ReadProcessMemory.argtypes=[HANDLE，LPCVOID，LPVOID，SIZE\u T，POINTER（SIZE\u T）]

OpenProcess.restype=HANDLE

CloseHandle.argtypes=[HANDLE]

。不要修改Python字符串。使用

Create_string_buffer

或仅使用常规ctypes语法创建数组，例如

bufferSize=201

buffer=（c_char*bufferSize）（

。请确保对out参数使用正确的类型，

bytesRead=SIZE\u T（）

。在Win64.BTW中是8个字节，参数2是地址。默认参数类型为32位

int

，给定值超出范围。我建议的

argtypes

使用

LPCVOID

作为此参数，即

void*

指针。
