问题描述：
我打算开发一款上位机程序，通过windows API 的nvme部分下发nvne指令给nvme 盘片，发现有很多问题，，我无法确定这种操作是否可行。（我的代码参考微软nvme部分示例）
 

 

报错内容：

deviceHandle = 180
protocolCommand->ReturnStatus: 0

result: 0
returnedLength: 0

Failed to send protocol command. Error code:
317请按任意键继续. . .
我的初步解决思路是参数配置不对，需要继续修改参数
操作环境是：Windows
软件是visual studio 2022
我的Nvme盘片，支持的协议是M2.0

问题：
1、我想问一下，这个开发可行性怎么样，理论上可以实现不，实际上可以实现不，怎么实现？
2、开发是否需要再开发一款windows pcie驱动，从而配套开发，开发代码怎么写？
3、在visual studio直接调用windows API的话，理论上可以实现不，实际上可以实现不，怎么实现？
4、我的程序代码遇到的问题怎么解决，有没有更好的方式？
