Is it possible to find out which display drivers are currently running using C++ WinAPI functions?

If it is, can you suggest what WinAPI function/s I use for this. I know that I can enable and disable the display drivers using the following functions: DrvEnableDriver & DrvDisableDriver.

The reason I am doing this is because I am attempting to make my 2nd monitor toggle from Duplicate/Mirrored Display to Extend Display. In my previous question someone suggested that I need to disable the currently running Extend Display Driver in order to make the 2nd monitor have duplicate display. I am hoping for WinAPI functions that work on Windows 2000 and up.
