I want to use ExtEscape to read/write hardware info in application. ExtEscape is an API in <wingdi.h>.

我想使用ExtEscape来读取/写入应用程序中的硬件信息。ExtEscape是 中的API。


What I want to know is that what can I do in KMD, and how to implement the function called by ExtEscape in KMD?

我想知道的是,我可以在KMD中做什么,以及如何在KMD上实现ExtEscape调用的函数?


This is the function declaration of ExtEscape

这是ExtEscape的函数声明:


int ExtEscape(
HDC hdc,
int nEscape,
int cbInput,
LPCSTR lpszInData,
int cbOutput,
LPSTR lpszOutData
);

I don't want to do it by creating a new device and add private function.
I want to use ExtEscape if this route is right.

我不想创建一个新设备并添加私人功能。如果这条路线是正确的,我想使用ExtEscape。
