ID3DXLine::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 IDirect3DDevice9::Reset. Even if the device was not actually lost, ID3DXLine::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 IDirect3DDevice9::Reset and then ID3DXLine::OnResetDevice.
