What does this code do?

static func prepareForDeviceMonitoring(){
        
        var prop = CMIOObjectPropertyAddress(
            mSelector: CMIOObjectPropertySelector(kCMIOHardwarePropertyAllowScreenCaptureDevices),

        CMIOObjectSetPropertyData(CMIOObjectID(kCMIOObjectSystemObject), &prop,
                                  0, nil,
                                  UInt32(MemoryLayout.size(ofValue: allow)), &allow)

I think that code might be related to programming on an Apple computer.  Perhaps it’s related to how the computer knows when to let you take screenshots.

What does CMIO stand for here?

It might be short for “Core Media IO”.  In many computers, the operating system lets you do lots of basic things on the computer, like take a screenshot, or change the volume, or attach a new device.  This code might have been written to configure your computer to know when to allow you to do those things.  That way your computer is more helpful.

Could you tell me what the code is meant to do and what language it’s in?
