IDirect3DSwapChain9 Interface

Applications use the methods of the IDirect3DSwapChain9 interface to manipulate a swap chain.

IDirect3DSwapChain9 Members

GetBackBuffer	Retrieves a back buffer from the swap chain of the device.
GetDevice	Retrieves the device associated with the swap chain.
GetDisplayMode	Retrieves the display mode's spatial resolution, color resolution, and refresh frequency.
GetFrontBufferData	Generates a copy of the swapchain's front buffer and places that copy in a system memory buffer provided by the application.
GetPresentParameters	Retrieves the presentation parameters associated with a swap chain.
GetRasterStatus	Returns information describing the raster of the monitor on which the swap chain is presented.
Present	Presents the contents of the next buffer in the sequence of back buffers owned by the swap chain.

Remarks

There is always at least one swap chain for each device, known as the implicit swap chain. However, an additional swap chain for rendering multiple views from the same device can be created by calling the IDirect3DDevice9::CreateAdditionalSwapChain method.

This interface, like all Component Object Model (COM) interfaces, inherits from the IUnknown interface.

The LPDIRECT3DSWAPCHAIN9 and PDIRECT3DSWAPCHAIN9 types are defined as pointers to the IDirect3DSwapChain9 interface.

typedef struct IDirect3DSwapChain9 *LPDIRECT3DSWAPCHAIN9, *PDIRECT3DSWAPCHAIN9;
