ID3DXFont::OnLostDevice method
Use this method to release all references to video memory resources and delete all stateblocks. This method should be called whenever a device is lost, or before resetting a device.
Syntax
HRESULT OnLostDevice();
Parameters
This method has no parameters.
Return value
Type: HRESULT
If the method succeeds, the return value is S_OK. If the method fails, the return value can be D3DERR_INVALIDCALL.
Remarks
This method should be called whenever the device is lost or before the user calls Reset. Even if the device was not actually lost, OnLostDevice is responsible for freeing stateblocks and other resources that may need to be released before resetting the device. As a result, the font object cannot be used again before calling Reset and then OnResetDevice.
