2199 * | ---More surfaces can follow--- |
2200 *
2201 * The reason is that the IWineD3DSwapchain(render target container)
2202 * and the IWineD3DTexure(Texture container) release the parents
2203 * of their surface's children, but by releasing the complex root
2204 * the surfaces which are complexly attached to it are destroyed
2205 * too. See IDirectDrawSurface::Release for a more detailed
2206 * explanation.
2207 *
2208 * Params:
2209 * DDSD: Description of the surface to create
2210 * Surf: Address to store the interface pointer at
2211 * UnkOuter: Basically for aggregation support, but ddraw doesn't support
2212 * aggregation, so it has to be NULL
2213 *
2214 * Returns:
2215 * DD_OK on success
2216 * CLASS_E_NOAGGREGATION if UnkOuter != NULL
2217 * DDERR_* if an error occurs
