Additional Information from the Direct3D Mobile Driver (Windows Embedded CE 6.0)
1/6/2010
The Microsoft® Direct3D® Mobile middleware contains a pass-through mechanism that allows the driver to expose to the application additional information beyond what the Direct3D Mobile capability bits define.
To retrieve this information, and application must obtain an adapter identifier for the driver by calling the IDirect3DMobile::GetAdapterIdentifier method. The application then calls the IDirect3DMobileDevice::GetInfo method to query the driver.
Upon receiving this call, the Direct3D Mobile middleware immediately flushes the command buffer and then calls the driver's D3DM_GetInfo function with the information provided by the application.
