请求使用 FFI-NAPI 调用 Dll 库时发现的问题的答案

Question

我很困惑。 使用 FFI-NAPI - Dll 时。 返回值不接收任何东西。 而是在终端打印出内容（stdut）。 我将在下面发布部分代码并继续尝试。我想使用 FF 回调后它会起作用，但我不确定。你能帮我看一下吗？

这是我的代码：

import {  myDll } from './utils/DllImport'
....
....
ipcMain.on('GetAdbProp', () => {
  var nameBuffer = Buffer.alloc(10240);
  nameBuffer.fill(0);
  nameBuffer.write('', 0, "ascii");
  const res=myDll.GetAdbProp('factory.board', nameBuffer)
  console.log(res,nameBuffer)
})

const ffi = require('ffi-napi')
const ref=require('ref-napi')
let path = require('path')
let dllFilePath;

if (process.env.NODE_ENV === 'development') {
   dllFilePath = path.join(process.cwd(), './resources/extraResources','AdbHandler.dll')
} else {
    dllFilePath = path.join(process.cwd(), './resources/extraResources','AdbHandler.dll')
}
let myDll =ffi.Library(dllFilePath, {
    'GetAdbProp':
        [
            ref.types.bool, ['string','char *'],
        ],
})
module.exports = {
    myDll
}

打印结果：

\platform-tools\adb.exe  shell "getprop | grep factory.board"
[factory.board.acclsensor]: [1]
[factory.board.brightness]: [0]
[factory.board.bt]: [1]

 const res=myDll.GetAdbProp('factory.board', nameBuffer)

这串代码返回一个空值，并且缓冲区没有改变，但是我的终端有一些东西，
我该如何使用这个打印输出（stduit内容），以下这些。

\platform-tools\adb.exe  shell "getprop | grep factory.board"
[factory.board.acclsensor]: [1]
[factory.board.brightness]: [0]
[factory.board.bt]: [1]
[factory.board.charge]: [-1]
.....
....
.....

谢谢
