IDirect3DMobileSwapChain::GetBackBuffer (Windows CE 5.0)
This method retrieves a back buffer from the swap chain of the device.
HRESULT GetBackBuffer( UINT BackBuffer, D3DMBACKBUFFER_TYPE Type, IDirect3DMobileSurface** ppBackBuffer);
Parameters
- BackBuffer
[in] Index of the back buffer object to return. Back buffers are numbered from 0 to the total number of back buffers - 1. A value of 0 returns the first back buffer, not the front buffer. The front buffer is not accessible through this method. - Type
[in] The only valid value for this parameter is D3DBACKBUFFER_TYPE_MONO (see D3DMBACKBUFFER_TYPE). - ppBackBuffer
[out] Address of a pointer to an IDirect3DMobileSurface interface that represents the returned back buffer surface.
Return Values
If the method succeeds, the return value is D3DM_OK (see D3DM Values).
If the method fails, the return value can be D3DMERR_INVALIDCALL (see D3DMERR Values).
Remarks
Calling this method will increase the internal reference count on the IDirect3DMobileSurface interface. Failure to call IUnknown::Release when finished using this IDirect3DMobileSurface interface results in a memory leak.
Requirements
OS Versions: Windows CE 5.0 and later.
Header: D3dm.h.
Link Library: D3dm.lib, D3dmguid.lib.
