handle_layer()

static xrt_result_t handle_layer ( struct xrt_compositor *  xc, struct xrt_device *  xdev, struct xrt_swapchain *  xsc, const struct xrt_layer_data *  data, enum xrt_layer_type  type  )

ipc_client_create_native_compositor()

xrt_result_t ipc_client_create_native_compositor	(	struct xrt_system_compositor *	xsysc,
		const struct xrt_session_info *	xsi,
		struct xrt_compositor_native **	out_xcn
	)

Create a native compositor from a system compositor, this is used instead of the normal xrt_system_compositor::create_native_compositor function because it doesn't support events being generated on the app side.

This will also create the session on the service side.

Parameters

	xsysc	IPC created system compositor.
	xsi	Session information struct.
[out]	out_xcn	Pointer to receive the created xrt_compositor_native.

ipc_client_create_system_compositor()

xrt_result_t ipc_client_create_system_compositor	(	struct ipc_connection *	ipc_c,
		struct xrt_image_native_allocator *	xina,
		struct xrt_device *	xdev,
		struct xrt_system_compositor **	out_xcs
	)

Create an IPC client system compositor.

It owns a special implementation of the xrt_system_compositor interface.

This actually creates an IPC client "native" compositor with deferred initialization. The ipc_client_create_native_compositor function actually completes the deferred initialization of the compositor, effectively finishing creation of a compositor IPC proxy.

Parameters

ipc_c	IPC connection
xina	Optional native image allocator for client-side allocation. Takes ownership if one is supplied.
xdev	Taken in but not used currently

Todo:

Parameters

[out]

out_xcs

Pointer to receive the created xrt_system_compositor.
