IDirect3DDevice9::GetRenderTarget Method

Retrieves a render target surface.

Syntax

HRESULT GetRenderTarget(      

    DWORD RenderTargetIndex,
    IDirect3DSurface9 **ppRenderTarget
);

Parameters

RenderTargetIndex
[in] Index of the render target. See Remarks.
ppRenderTarget
[out] Address of a pointer to an IDirect3DSurface9 interface, representing the returned render target surface for this device.

Return Value

If the method succeeds, the return value is D3D_OK.
If the method fails, the return value can be D3DERR_INVALIDCALL if one of the arguments is invalid, or D3DERR_NOTFOUND if there's no render target available for the given index.

Remarks

The device can now support multiple render targets. The number of render targets supported by a device is contained in the NumSimultaneousRTs member of D3DCAPS9. See Multiple Render Target.
Calling this method will increase the internal reference count on the IDirect3DSurface9 interface. Failure to call IUnknown::Release when finished using the IDirect3DSurface9 interface results in a memory leak.
