The WFDCloseSession function closes a session after a previously successful call to the WFDStartOpenSession function.
DWORD WFDCloseSession( HANDLE hSessionHandle );
A session handle to a Wi-Fi Direct session. This is a session handle previously returned by the WFDStartOpenSession function.
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 handle is invalid.
This error is returned if the handle specified in the hSessionHandle parameter was not found in the handle table.
The parameter is incorrect.
This error is returned if the hSessionHandle parameter is NULL or not valid.
The group or resource is not in the correct state to perform the requested operation.
This error is returned if the Wi-Fi Direct service is disabled by group policy on a domain.
||Various error codes.|
The WFDCloseSession 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 WFDCloseSession function queues a future work item to close the session, so disconnection may not be immediate.
Calling the WFDCloseSession function while a WFDStartOpenSession call is pending will not close the session.
It is the responsibility of the caller to pass the WFDCloseSession function a handle in the hSessionHandle parameter that was returned from a successful asynchronous call to the WFDStartOpenSession function.
Calling the WFDCloseSession function with a handle that was valid and has become invalid will yield undefined results.
