Remarks
The WFDCloseHandle 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.
In order to use Wi-Fi Direct, an application must first obtain a handle to the Wi-Fi Direct service by calling the WFDOpenHandle function. The Wi-Fi Direct (WFD) handle returned by the WFDOpenHandle function is used for subsequent calls made to the Wi-Fi Direct service. Once an application is done using the Wi-Fi Direct service, the application should call the WFDCloseHandle function to signal to the Wi-Fi Direct service that the application is done using the service. This allows the Wi-Fi Direct service to release resources used by the application.
