Supported IOCTL commands in metro apps

Question

Where can I get the list of supported IOCTL commands in Metro style apps? This is for checking if it is possible to send ioctl commands via the CreateFile2 route similar to the way we used to do in Desktop app. I hope we know that we can issue ioctl commands via CreateDeviceAccessInstance() API etc from metro apps. The same is being done in the Custom Device access sample. Also , should the device meta data necessariliy be present in the app manifest in order to successfully send IOCTL commands to these devices?

Answer 1

The Custom device access sample supports IOCTLs however standard Metro style apps do not.

Hi,

Is a custom device a specialized device like a camera, microhone etc?

Is custom device access sample  a special application that can access specialized devices only?

How does this app differ from standard metro apps?
