从外部 C 代码导入在 Cython 中不起作用

Question

基本上我只从这个 github 存储库中提取了 avscan 样本avscan，我想重新定义/复制并粘贴用户模式主要功能中的代码，并在我的 Cython 代码中实现它，如下所示。

cythonmod.pyx:

cdef extern from *:
    r"""
    #include <windows.h>
    #include <stdio.h>
    #include <fltUser.h>
    #include "..\\avscan\\user\\utility.h"
    #include "..\\avscan\\inc\\avlib.h"
    #include "..\\avscan\\user\\userscan.h"
    
    HRESULT UserScanInit(PUSER_SCAN_CONTEXT pContext);
    
    int usermodeDef(){
        printf("User mode connecting to kernel mode\n");
        UCHAR c;
        HRESULT hr = S_OK;
        USER_SCAN_CONTEXT userScanCtx = {0};
    
    
        hr = UserScanInit(&userScanCtx);
        if (FAILED(hr)) {
            fprintf(stderr, "Failed to initialize user scan data\n");
            DisplayError( hr );
            return 255;
        }
        
        //
        //  Read user's input until it reads 'q'
        //
        
        for(;;) {
        
            printf("press 'q' to quit: ");
            c = (unsigned char) getchar();
            if (c == 'q') {
            
                break;
            }
        }
        
        //
        //  Finalize the scan thread contexts.
        //
    
        hr = UserScanFinalize(&userScanCtx);
        if (FAILED(hr)) {
            fprintf(stderr, "Failed to finalize the user scan data.\n");
        }
        return 0;
    }
    """

    int usermodeDef()

setup.py

from distutils.core import setup, Extension
from Cython.Build import cythonize

ext_modules = [
    Extension(
        "cythonmod",
        sources=["cythonmod.pyx"],
        include_dirs=["../avscan/inc", "../avscan/user"],
        extra_compile_args=["-include", "../avscan/user/userscan.h"],
    ),
]

setup(
    name="avscanner",
    ext_modules=cythonize(ext_modules),
    compiler_directives={'language_level': 3, "unraisable_tracebacks": True}
)

当我在这里运行 setup.py 时，我得到了

UserScanInit

未定义的错误。

setup.py 生成的 GCC 选项：

gcc -mdll -O -Wall -I../avscan/inc -I../avscan/user -IC:\Users\username\AppData\Local\Programs\Python\Python39\include -IC:\Users\username\AppData\Local\Programs\Python\Python39\include -c cythonmod.c -o build\temp.win-amd64-3.9\Release\cythonmod.o -include ../avscan/user/userscan.h

我尝试了很多其他的东西，即从

cdef extern

直接导入 userscan.h 作为

"../avscan/user/userscan.h"

：但仍然无法修复它。

谁能告诉我如何将外部 C 代码导入 cython 的内联 C？
