View the official Windows Driver Kit DDI referenceNo description available.
The FinishSessionKeyRefresh function indicates that all buffers from that point in time use the updated session key value.
hDeviceA handle to the display device (graphics context).
unnamedParam2pData [in]
A pointer to a D3DDDIARG_FINISHSESSIONKEYREFRESH structure that describes the session.
FinishSessionKeyRefresh returns one of the following values:
| Return code | Description |
|---|---|
| S_OK | The session is successfully updated. |
| D3DDDIERR_NOTAVAILABLE | The driver does not support the FinishSessionKeyRefresh function. |
The hardware and driver can optionally support the FinishSessionKeyRefresh function for all crypto types.
When the Direct3D runtime calls the driver's StartSessionKeyRefresh function, the driver generates and saves a random number and returns the random number in the buffer that the pRandomNumber member of the D3DDDIARG_STARTSESSIONKEYREFRESH structure points to.
When the runtime subsequently calls the driver's FinishSessionKeyRefresh function, the driver performs an XOR operation of the random number with the session key.
