The WFDOpenLegacySession function retrieves and applies a stored profile for a Wi-Fi Direct legacy device.
DWORD WFDOpenLegacySession( HANDLE hClientHandle, PDOT11_MAC_ADDRESS pLegacyMacAddress, HANDLE *phSessionHandle, GUID *pGuidSessionInterface );
A HANDLE to the Wi-Fi Direct service for this session. This parameter is retrieved using the WFDOpenHandle function.
A pointer to Wi-Fi Direct device address of the legacy client device.
A pointer to a HANDLE to receive the handle to the Wi-Fi Direct service for this session.
If the WFDOpenLegacySession function is successful, a handle to the Wi-Fi Direct service to use in this session is returned.
A pointer to the GUID of the network interface for this session.
If the WFDOpenLegacySession function is successful, a GUID of the network interface on which Wi-Fi Direct session is returned.
If the function succeeds, the return value is ERROR_SUCCESS.
If the function fails, the return value may be one of the following return codes.
The parameter is incorrect.
This error is returned if the phClientHandle or the pLegacyMacAddress parameter is NULL.
Not enough storage is available to process this command.
This error is returned if the system was unable to allocate memory to create the client context.
||Various error codes.|
The WFDOpenLegacySession 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 WFDOpenLegacySession or 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. The WFDOpenLegacySession function is used to retrieve and apply a stored profile for a Wi-Fi Direct legacy device.
The WFDOpenLegacySession function retrieves the stored legacy profile for device from the profile store for the specified legacy device address. This device address must be obtained from a Device Node created as a result of the Inbox pairing experience (Legacy WPS Pairing).
Once an application is done using the Wi-Fi Direct service, the application should call the WFDCloseSession function to close the session and 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.
