Remarks
The WFDUpdateDeviceVisibility function is part of Wi-Fi Direct, a new feature in Windows 8 and Windows Server 2012. Wi-Fi Direct is based on the development of the Wi-Fi Peer-to-Peer Technical Specification v1.1 by the Wi-Fi Alliance (see Wi-Fi Alliance Published Specifications). The goal of the Wi-Fi Peer-to-Peer Technical Specification is to provide a solution for Wi-Fi device-to-device connectivity without the need for either a Wireless Access Point (wireless AP) to setup the connection or the use of the existing Wi-Fi adhoc (IBSS) mechanism.
The WFDUpdateDeviceVisibility function will perform a targeted Wi-Fi Direct discovery, and will update the DEVPKEY_WiFiDirect_IsVisibile property key on the device node for the given device.
