Function ovr_sys::directx::ovr_GetMirrorTextureBufferDX [−] [src]

pub unsafe extern "C" fn ovr_GetMirrorTextureBufferDX(
    session: ovrSession, 
    mirrorTexture: ovrMirrorTexture, 
    iid: IID, 
    out_Buffer: *mut *mut c_void
) -> ovrResult

Get the underlying buffer as any compatible COM interface (similar to QueryInterface)

in session Specifies an ovrSession previously returned by ovr_Create.

in mirrorTexture Specifies an ovrMirrorTexture previously returned by ovr_CreateMirrorTextureDX

in iid Specifies the interface ID of the interface pointer to query the buffer for.

out out_Buffer Returns the COM interface pointer retrieved.

Returns an ovrResult indicating success or failure. In the case of failure, use ovr_GetLastErrorInfo to get more information.

Example code, not translated from C

ID3D11Texture2D* d3d11Texture = nullptr;
ovr_GetMirrorTextureBufferDX(session, mirrorTexture, IID_PPV_ARGS(&d3d11Texture));
d3d11DeviceContext->CopyResource(d3d11TextureBackBuffer, d3d11Texture);
d3d11Texture->Release();
dxgiSwapChain->Present(0, 0);
