ISurfacePresenterFlip::GetBuffer method
Gets an interface pointer for the indicated back buffer.
Syntax
HRESULT GetBuffer( [in] UINT backBufferIndex, [in] REFIID riid, [out, retval] iid_is(riid) void** ppBuffer );
Parameters
- backBufferIndex [in]
- riid [in]
- ppBuffer [out, retval]
Return value
If this method succeeds, it returns S_OK. Otherwise, it returns an HRESULT error code.
Remarks
The riid specifies the requested interface.
This method is used in the same way as ISurfacePresenter::Present. The main difference is that the index refers to a different buffer after each present, in a similar way to how IDXGISwapChain buffers work. Buffer 0 is always the next buffer that will be presented.
