IDirectDrawSurface::GetAttachedSurface
| Microsoft DirectShow 9.0 |
IDirectDrawSurface::GetAttachedSurface
The GetAttachedSurface method finds the attached surface that has the specified capabilities. Attachments are used to connect multiple DirectDrawSurface objects into complex structures like the ones needed to support 3-D page flipping with Z buffers. GetAttachedSurface will fail if there is more than one surface attached which matches the capabilities requested. In this case the application must use EnumAttachedSurfaces to obtain the non-unique attached surfaces.
