Tracking BitBlts system wide

Venkat_Subramanian · August 23, 2006, 6:21am

I saw the mirror video driver in DDK samples. I am new to device driver development and need help with the following -

Track calls to Win32 BitBlt API in the driver. Where/how exactly to modify the sample driver to do this?
Identify the window corresponding to the device contexts in the original BitBlt call. I was not sure how to get the original Win32 DC handle from the SURFACE parameters that are part of the EngBitBlt/DrvBitBlt call.

Thanks
Venkat
