Writing API to use some functions of Windows Device Driver

Question

I would request you to please help me out and guide me to the right track. I am supposed to right an API using the already available functions in the windows Touchpad driver, like I want to have the x and y coordinate every time the touch is made, I want to have the pressure value, and I want to read speed and acceleration values as well.

How should I go about it, I am really very confused right now. I am unable to find any tutorial or help on this, please guide me through.

I will be very thankful for your time and consideration.

Regards

Answer 1

One possible path is DeviceIOControl.

the second thing you need is the specific control operations for the touchpad. I can't find any evidence that these are documented openly.

Another possible path is The HID API, since the touchpad is a human interface device.
