python - 如何在 python 64bit 中枚举模块

Question

我有一段代码在 32 位中运行良好，我正在尝试使其在 64 位中也能运行。运行该进程时，sizeof(structure) 似乎返回无效选项，并且未针对 64 位正确填充结构。我需要做什么才能在 64 位中实现此功能？

尝试使用 correct definition :

class MODULEENTRY32(Structure):
    _fields_ = [( 'dwSize' , DWORD ) , 
                ( 'th32ModuleID' , DWORD ),
                ( 'th32ProcessID' , DWORD ),
                ( 'GlblcntUsage' , DWORD ),
                ( 'ProccntUsage' , DWORD ) ,
                ( 'modBaseAddr' , POINTER(BYTE) ) ,
                ( 'modBaseSize' , DWORD ) , 
                ( 'hModule' , HMODULE ) ,
                ( 'szModule' , c_char * 256 ),
                ( 'szExePath' , c_char * 260 ) ]
