WlanCloseHandle function (wlanapi.h)
The WlanCloseHandle function closes a connection to the server.
DWORD WlanCloseHandle( [in] HANDLE hClientHandle, PVOID pReserved );
The client's session handle, which identifies the connection to be closed. This handle was obtained by a previous call to the WlanOpenHandle function.
Reserved for future use. Set this parameter to NULL.
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.
||hClientHandle is NULL or invalid, or pReserved is not NULL.|
||The handle hClientHandle was not found in the handle table.|
||Various error codes.|
After a connection has been closed, any attempted use of the closed handle can cause unexpected errors. Upon closing, all outstanding notifications are discarded.
Do not call WlanCloseHandle from a callback function. If the client is in the middle of a notification callback when WlanCloseHandle is called, the function waits for the callback to finish before returning a value. Calling this function inside a callback function will result in the call never completing. If both the callback function and the thread that closes the handle try to acquire the same lock, a deadlock may occur. In addition, do not call WlanCloseHandle from the DllMain function in an application DLL. This could also cause a deadlock.
