allocateSharedImages()

xrt_result_t xrt::auxiliary::d3d::d3d11::allocateSharedImages	(	ID3D11Device5 &	device,
		const xrt_swapchain_create_info &	xsci,
		size_t	image_count,
		bool	keyed_mutex,
		std::vector< wil::com_ptr< ID3D11Texture2D1 > > &	out_images,
		std::vector< HANDLE > &	out_handles
	)

Allocate images (ID3D11Texture2D1) that have a corresponding native handle.

Parameters

	device	A D3D device to allocate with.
	xsci	Swapchain create info: note that the format is assumed to be a DXGI_FORMAT (conversion to typeless is automatic)
	image_count	The number of images to create.
	keyed_mutex	Whether to create images with a shared "keyed mutex" as well
[out]	out_images	A vector that will be cleared and populated with the images.
[out]	out_handles	A vector that will be cleared and populated with the corresponding native handles.

Returns

xrt_result_t, one of:

• XRT_SUCCESS
• XRT_ERROR_ALLOCATION
• XRT_ERROR_SWAPCHAIN_FORMAT_UNSUPPORTED
• XRT_ERROR_SWAPCHAIN_FLAG_VALID_BUT_UNSUPPORTED
• XRT_ERROR_D3D11
